Oracle shares fell as much as 2% in extended trading Thursday after the company posted earnings in the second quarter that exceeded analysts’ expectations. Shares rebounded after the company issued a better-than-expected quarterly forecast.

This is how the company did it:

  • Merits: $ 1.06 per share, adjusted versus $ 1.00 per share as analysts expected, according to Refinitive
  • Revenue: According to Refinitiv, $ 9.80 billion versus $ 9.79 billion as analysts expected.

Oracle’s revenue increased nearly 2% year over year for the quarter ended November 30, according to a statement. In the previous quarter, sales rose by almost 2%.

The company pointed to the growth of cloud services, which are in greater demand this year as the coronavirus has forced many corporate employees to telework. At the same time, it continues to provide more traditional services to businesses, some of which have been hard hit by the pandemic.

“We would have achieved more revenue growth if we hadn’t had any capacity constraints at OCI in the second quarter,” said Larry Ellison, co-founder and chairman of Oracle, the analysts in a conference call. He was referring to Oracle’s cloud infrastructure that competes with Amazon Web Services and Microsoft Azure.

Oracle’s largest business, cloud services and license support, had revenue of $ 7.11 billion, up 4% year over year and above the consensus estimate of $ 7.04 billion among analysts surveyed by FactSet . Oracle’s revenue from second-generation cloud infrastructures rose 139% for the quarter, Oracle CEO Safra Catz said on the conference call.

However, smaller parts of the Oracle business declined. The company’s cloud licensing and on-premises licensing segments contributed $ 1.09 billion to revenue, down 3%. Analysts polled by FactSet had searched for $ 1.13 billion.

Oracle’s hardware sales were $ 844 million, a 3% decrease, despite being just above the FactSet analyst consensus of $ 838 million. The company’s service revenue of $ 752 million was slightly above the consensus of $ 750 million, but was down 7%.

“So the pandemic has some negative effects on us, some positive effects on us, simply because of our size and breadth of customer base, it affects them differently,” said Catz. “And so, obviously, our hospitality customers have had a tough time. Some of our retail customers did terrible, others did very, very well.”

In the quarter, President Donald Trump said he had basically agreed to a deal to move US user data for the TikTok video sharing app to Oracle’s cloud infrastructure. Oracle said it would become a 12.5% ​​owner of TikTok Global as part of the deal. The deal is not final.

Oracle also announced the availability of a cloud service that allows organizations to monitor the health of various parts of applications running in clouds and on-premises centers.

With regards to the guidance, Catz expects the company to achieve adjusted earnings per share of $ 1.09-1.13 and annualized revenue growth of 2-4 percent for the third quarter of fiscal year. Analysts polled by Refinitiv had expected adjusted earnings per share of $ 1.04 and revenue of $ 9.95 billion, representing a growth of 1.5%.

Excluding the after-hours move, Oracle’s shares are up about 12% since early 2020, while the S&P 500 is up nearly 14%.

Covid-19 Information: Reside Updates – The New York Occasions

Here’s what you need to know:

Credit…Steve Helber/Associated Press

Pennsylvania announced statewide restrictions on Thursday that ban indoor dining and close gyms, theaters and casinos for three weeks to stem a “dire” surge in coronavirus cases, and Virginians were asked to stay home from midnight to 5 a.m. until the new year.

The clampdowns came as states across the country reported deaths and cases in numbers never seen before, and hospitals filled beyond capacity. Through Wednesday, there were seven-day records in both cases and deaths.

In Pennsylvania, Gov. Tom Wolf was unsparing Thursday in his characterization of the threat facing his state.

“This virus continues to rage in Pennsylvania,” Mr. Wolf said at a news conference. “Clearly we need to take future mitigation actions and stop the spread of Covid-19. We all hoped it would not come to this. The current state of the surge in Pennsylvania will not allow us to wait.”

And in Virginia, Gov. Ralph Northam announced a new executive order that imposes a nightly curfew, but it was unclear how — and how vigorously — it would be enforced.

The order lists categories of activity that will still be permitted during the curfew, including obtaining food, goods or services; seeking medical or law enforcement help; taking care of people or animals; child care; exercise; traveling to work, school or a house of worship; volunteering for charity; and leaving home to seek safety.

The governor urged residents not to go out without good reason. “We need to take this seriously,” Mr. Northam said. “We need to stay at home.”

But asked how the curfew would be enforced, the governor said it was “about messaging.”

Virginia reported at least 21 new coronavirus deaths and 4,398 new cases on Wednesday. Over the past week, the state has reported an average of 3,521 cases a day, an increase of 41 percent from the average two weeks earlier.

The new order also prohibits all public and private in-person gatherings of more than 10 people who do not live together, with exceptions for work and education, and requires people to wear masks “if they are in an indoor setting shared by others.” The state already requires masks outdoors.

Oklahoma also limited indoor activity, restricting indoor youth sporting events and public gatherings — which includes weddings, funerals and holiday parties held at event centers — to 50 percent capacity for the next 30 days. Places of worship are excluded.

On Wednesday, Pennsylvania reported 8,626 new cases and an additional 247 coronavirus deaths. The daily average over the past week has hovered near 10,000 cases per day, an increase of 51 percent from the average two weeks earlier.

Dr. Jaewon Ryu, the president and chief executive officer of Geisinger Health System, a regional hospital system, said the network was “operating pretty close to 100 percent capacity.”

Mr. Wolf, who announced on Wednesday that he had tested positive for the coronavirus and would be performing his duties remotely, said he was feeling well and that he had tested negative on Thursday. Mr. Wolf’s wife, Francis Wolf, also tested negative.

It was not immediately clear what type of test Mr. Wolf took, or if he had previously felt sick. Some types of coronavirus tests are prone to delivering incorrect results, especially when they are taken by people who are not experiencing symptoms.

Even before Governor Wolf issued his new order, the Pennsylvania House majority leader, Kerry Benninghoff, a Republican, pushed back against what many suspected was coming.

“Governor Wolf, do not cancel Christmas,” Mr. Benninghoff said in a statement. “Do not use your executive order pen to devastate lives and livelihoods. Government mandates will not cure COVID-19 and unilateral shutdowns will not create personal responsibility.”

In Virginia, speaking on the first night of Hanukkah, the governor also called on citizens to remember service members and essential workers during the holiday season.

“I know that Christmas and Hanukkah are truly cherished times,” he said. “The holidays look a bit different this year, and some of the traditions we treasure just aren’t possible.”

But he added, “As we look ahead to a new year, I see reason for hope and optimism that in the coming months, things will be better.”

Pfizer’s Covid-19 vaccine passed a critical milestone on Thursday when a panel of experts formally recommended that the Food and Drug Administration authorize its use.

The F.D.A.’s vaccine advisory panel, composed of independent scientific experts, infectious disease doctors and statisticians, voted in favor of emergency authorization for people 16 and older.

Although the F.D.A. does not have to follow the advice of its advisory panel, it usually does, and it is likely to do so within days, giving health care workers and nursing home residents first priority to begin receiving the first shots early next week.

The agency may act as soon as Saturday, though officials cautioned that last-minute legal or bureaucratic requirements might delay an announcement.

With that formal blessing, the nation may finally begin to slow the spread of the virus just as infections and deaths surge, reaching a record of more than 3,000 daily deaths on Wednesday.

The initial shipment of 6.4 million doses will leave Pfizer warehouses within 24 hours of being cleared by the F.D.A., according to federal officials. About half of those doses will be sent across the country, and the other half will be reserved for the initial recipients to receive their second dose about three weeks later.

It is the beginning of a complex, monthslong distribution plan coordinated by federal and local health authorities, as well as large hospitals and pharmacy chains.

If successful, the vaccine campaign should help return a grieving and economically depressed country back to some semblance of normal.

“With the high efficacy and good safety profile shown for our vaccine, and the pandemic essentially out of control, vaccine introduction is an urgent need,” Kathrin Jansen, a senior vice president and the head of vaccine research and development at Pfizer, said at the meeting.

The recommendation vote caps a whirlwind year for Pfizer and its German partner BioNTech, which began working on the vaccine 11 months ago, shattering all speed records for vaccine development, which typically takes years.

The Pfizer vaccine has already been given to people in Bahrain and Britain. Canada approved it on Wednesday. A U.S. authorization for it is expected to be followed soon by one for Moderna’s vaccine, which uses similar technology and has also shown promising results in clinical trials.

The editor in chief of a weekly report from the Centers for Disease Control and Prevention has told House Democrats that she was ordered to destroy an email showing that Trump political appointees attempted to interfere with its publication — and that she believes the order came from Dr. Robert R. Redfield, the agency’s director.

The explosive allegation from Dr. Charlotte Kent, the editor of the C.D.C.’s Morbidity and Mortality Weekly Report — the so-called “holiest of the holy” of health reports — is contained in a letter that Representative James E. Clyburn of South Carolina, the No. 3 House Democrat, sent Thursday morning to Dr. Redfield and the health secretary, Alex M. Azar II.

The email in question, dated Aug. 8, was sent by Dr. Paul Alexander, then a senior H.H.S. adviser, Mr. Clyburn’s letter said. In it, Dr. Alexander demanded that the C.D.C. insert new language in a previously published scientific report on coronavirus risks to children, or “pull it down and stop all reports immediately.”

Dr. Kent was on vacation when it arrived; the request to delete the message, she told investigators, was passed on to her by the woman who was filling in for her. She considered the request “very unusual,” she said. And when she tried to comply, she discovered the email had already been deleted — but she told investigators she had “no idea” by whom.

Dr. Redfield has said that the scientific integrity of the M.M.W.R., as the reports are known, has never been compromised — a point he reiterated in a statement on Thursday. He did not deny the order to delete the email, but said he had “instructed C.D.C. staff to ignore” Mr. Alexander’s comments.

“As I testified before Congress, I am fully committed to maintaining the independence of the M.M.W.R., and I stand by that statement.” Dr. Redfield said.

A separate statement from the C.D.C.’s parent agency, the Department of Health and Human Services, called Mr. Clyburn’s letter “irresponsible” and said it mischaracterized Dr. Kent’s testimony. House Republicans then released excerpts from Dr. Kent’s testimony in which she said she was “very committed to maintaining the scientific integrity of the M.M. WR.,” and would never let anything interfere with that.

Mr. Clyburn, who leads a committee that is investigating political interference with the C.D.C., wrote that after Dr. Kent spoke to the panel on Monday, the Trump administration abruptly canceled four more interviews with top C.D.C. scientists and officials, a move the congressman said amounted to obstructing his investigation.

“I am deeply concerned that the Trump administration’s political meddling with the nation’s coronavirus response has put American lives at greater risk,” Mr. Clyburn wrote, “and that administration officials may have taken steps to conceal and destroy evidence of this dangerous conduct.”

He told Mr. Azar and Dr. Redfield that if theydid not produce documents requested by his panel by Dec. 15, he would subpoena the records.

The issue of political interference in the weekly reports burst into the news in September, when current and former senior health officials disclosed that H.H.S. political appointees had repeatedly asked the C.D.C. to revise, delay and even scuttle reports on the coronavirus that they believed were unflattering to President Trump.

One point of contention was the C.D.C.’s guidance on school openings.

Mr. Clyburn’s letter quoted Mr. Alexander’s email as saying: “C.D.C. tried to report as if once kids get together, there will be spread and this will impact school reopening. … Very misleading by C.D.C. and shame on them. Their aim is clear. … This is designed to hurt this Presidnet [sic] for their reasons which I am not interested in.”

Mr. Alexander was dismissed from the department in September.

The committee is now seeking to interview the four other C.D.C. officials whose appearances were canceled: Dr. Anne Schuchat, the principal deputy director; Nina Witkofsky, the acting chief of staff; Trey Moeller, the acting deputy chief of staff; and Kate Galatas, the acting associate director for communications.

Wealthy nations have a firm upper hand in securing a coronavirus vaccine compared with developing countries, a global coalition of organizations and activists warned on Wednesday.

In about 70 developing countries, only one in 10 residents is expected to receive a Covid-19 vaccine within the next year, according to the People’s Vaccine Alliance, which consists of organizations such as Amnesty International, Frontline AIDS, Global Justice Now and Oxfam.

“The hoarding of vaccines actively undermines global efforts to ensure that everyone, everywhere can be protected from Covid-19,” said Steve Cockburn, Amnesty International’s head of economic and social justice. “Rich countries have clear human rights obligations not only to refrain from actions that could harm access to vaccines elsewhere, but also to cooperate and provide assistance to countries that need it.”

Rich countries representing 14 percent of the global population have bought over 50 percent of promising Covid-19 vaccines, according to data collected by Airfinity, a London-based software company tracking deals between countries and manufacturers. It looked at supply deals that included eight vaccine candidates in Phase 3 clinical trials.

The alliance called on pharmaceutical companies along with researchers to “share the science, technological know-how and intellectual property” of their vaccines. They also asked governments to ensure their Covid-19 vaccines are free to the public and equitably available.

Recently, countries including South Africa and India have pushed for loosened restrictions on intellectual property rights for Covid-19 vaccines, proposing that the World Trade Organization end global enforcement of the rights in the interest of accessibility.

“Governments must also ensure the pharmaceutical industry puts people’s lives before profits,” said Heidi Chow, a senior campaign and policy manager at Global Justice Now.

Developing countries that the alliance focused on currently have access to the vaccine only through Covax, a global initiative to vaccinate much of the world population. (The United States declined to be a part of the effort.)

The United Kingdom started vaccinations this week, after becoming the first Western country to authorize a Covid-19 vaccine. On Wednesday, the United Arab Emirates approved China’s coronavirus vaccine, signaling a win for that country’s vaccine ambitions. Canada approved Pfizer and BioNTech’s coronavirus vaccine, which was also approved in Britain. Both Pfizer and Moderna have submitted their applications for emergency approvals the U.S. Food and Drug Administration and vaccinations in the U.S. could start before next month.

However, the news of vaccination success in wealthy nations hasn’t necessarily equated to access for developing countries: Wealthy nations have purchased enough doses to vaccinate their populations three times over by the end of 2021, the alliance said.

“By buying up the vast majority of the world’s vaccine supply, rich countries are in breach of their human rights obligations,” Mr. Cockburn said. “Instead, by working with others to share knowledge and scale up supply, they could help bring an end to the global Covid-19 crisis.”

Pandemic Unemployment

Assistance claims

Jump in claims the week after Thanksgiving

Applications for jobless benefits resumed their upward march last week as the worsening pandemic continued to take a toll on the economy.

More than 947,000 workers filed new claims for state unemployment benefits last week, the Labor Department said Thursday. That was up nearly 229,000 from the week before, reversing a one-week dip that many economists attributed to the Thanksgiving holiday. Applications have now risen three times in the last four weeks, and are up nearly a quarter-million since the first week of November.

On a seasonally adjusted basis, the week’s figure was 853,000, an increase of 137,000.

Nearly 428,000 applied for Pandemic Unemployment Assistance, a federal program that covers freelancers, self-employed workers and others who don’t qualify for regular state benefits.

Unemployment filings have fallen greatly since last spring, when as many as six million people a week applied for state benefits. But progress had stalled even before the recent increases, and with Covid-19 cases soaring and states reimposing restrictions on consumers and businesses, economists fear that layoffs could surge again.

“It’s very clear the third wave of the pandemic is causing businesses to have to lay people off and consumers to cut back spending,” said Daniel Zhao, senior economist for the career site Glassdoor. “It seems like we’re in for a rough winter economically.”

Jobless claims rose in nearly every state last week. In California, where the state has imposed strict new limits on many businesses, applications jumped by 47,000, more than reversing the state’s Thanksgiving-week decline.

The monthly jobs report released on Friday showed that hiring slowed sharply in early November and that some of the sectors most exposed to the pandemic, like restaurants and retailers, cut jobs for the first time since the spring. More up-to-date data from private sources suggests that the slowdown has continued or deepened since the November survey was conducted.

“Every month, we’re just seeing the pace of the recovery get slower and slower,” said AnnElizabeth Konkel, an economist with the job site Indeed. Now, she said, the question is, “Are we actually going to see it slide backward?”

Many economists say the recovery will continue to slow if the government does not provide more aid to households and businesses. After months of gridlock in Washington, prospects for a new round of federal help have grown in recent days, with congressional leaders from both parties signaling their openness to a compromise and the White House proposing its own $916 billion spending plan on Tuesday. But the two sides remain far apart on key issues.

The stakes are particularly high for jobless workers depending on federal programs that have expanded and extended unemployment benefits during the pandemic. Those programs expire later this month, potentially leaving millions of families with no income during what epidemiologists warn could be some of the pandemic’s worst months.

The New Hampshire State Legislature was already fiercely divided over the coronavirus when the new Republican speaker of the House of Representatives, Richard Hinch, died suddenly on Wednesday. Then came the news on Thursday that the cause of his death was Covid-19.

Mr. Hinch, who was 71, died just a week after he was sworn in as speaker — and about three weeks after an indoor meeting of his caucus that led to several members contracting the virus, an event that Mr. Hinch had tried to play down in public remarks. It was not clear whether he, too, had caught the virus at the caucus meeting.

The news will undoubtedly heighten tensions among state lawmakers, who have been at odds over the refusal of many Republican lawmakers to wear masks or take other pandemic precautions seriously. Splits have opened not just along partisan lines but also within the Republican ranks.

William M. Marsh, a Republican state representative, said the responsibility for Mr. Hinch’s death lies on the shoulders of a group of Republican members who refused to take precautions like wearing masks and maintaining social distance, and who leaned on others to do the same. “The peer pressure from colleagues is the root cause of what happened to my friend,” Mr. Marsh said of Mr. Hinch.

Democratic lawmakers, who held a majority before the Nov. 3 election, have been in an uproar over the Republican caucus meeting, which was held on Nov. 20 at a ski area. Democrats say they were kept in the dark about the infected lawmakers while Republicans were informed.

The Democratic former speaker, Steve Shurtleff, said he was troubled by Mr. Hinch’s support of Republican lawmakers who refused to wear masks on the House floor, whom Mr. Hinch had called the “patriot section” and the “freedom group.”

“It’s so ironic, looking back,” Mr. Shurtleff said on Thursday. “I know he was just doing his job as a Republican leader, defending his members and his caucus, but it seems so senseless now.”

Mr. Shurtleff said he hoped that the acting speaker would arrange for the House to meet remotely when its next session convenes in January, because he did not expect the mask-resistant Republicans to change their behavior. “I don’t think there will be any remorse,” he said. “There may be remorse at his passing, but not so much at the cause.”

Gov. Chris Sununu, a Republican, said on Wednesday that Mr. Hinch was “a fierce defender” of the state, “a close friend and a respected public servant.” He, too, was critical of lawmakers who refuse to wear masks. “For those who are out there doing just the opposite, just to make some sort of bizarre political point, it’s horribly irresponsible,” he said. “Use your heads, don’t act like a bunch of children.”

The State Senate and House each held their organizational meetings outdoors in 40-degree weather last week. About 130 members of the 400-seat House did not attend in person and were sworn in remotely, according to The Associated Press.

Republican lawmakers in at least two other states where mask wearing and other restrictions have been politically contentious have tested positive in recent days:

  • A South Dakota state senator who attended a dinner with the governor on Monday, and then joined dozens of lawmakers for a budget speech on Tuesday, tested positive on Wednesday. Senator Helene Duhamel of Rapid City posed for a group photo, shoulder to shoulder with Gov. Kristi Noem and more than two dozen other women who attended the dinner. Governor Noem has fiercely resisted imposing a mask mandate or any other restrictions throughout the pandemic, even as the coronavirus raged through the state in the fall, overwhelming its hospitals. The governor’s office insisted that she had not had close contact with Ms. Duhamel, even though they were photographed standing only a few feet apart.

  • The chairman of the appropriations committee in the North Dakota State Senate, Ray Holmberg, confirmed to The Bismarck Tribune on Thursday that he had tested positive, and said he believed he was infected with the virus during the legislature’s organizational session last week. Three employees of the legislature’s nonpartisan research agency have also tested positive, The Associated Press reported.

“The Ellen DeGeneres Show” has paused filming after its host said on Thursday that she had tested positive for the coronavirus.

“Fortunately, I’m feeling fine right now,’’ Ms. DeGeneres wrote in a statement she posted to Twitter.

Ms. DeGeneres said that anyone who had been in close contact with her had been notified, and that she was following guidelines from the Centers for Disease Control and Prevention.

“I’ll see you all again after the holidays,’’ she wrote. “Please stay healthy and safe.’’

The production company Telepictures, which is a unit of Warner Bros. Television, said in a statement that it had paused filming until January.

The talk show, which films in Burbank, Calif., has been a staple of daytime television since 2003.

After shifting to virtual audiences amid the pandemic, Ms. DeGeneres had resumed filming with a limited live audience in late October. Attendees were required to wear face masks and sit six feet apart.

Ms. DeGeneres had faced accusations of leading a toxic workplace earlier this year, after BuzzFeed News published an article in July in which former staff members said they faced “racism, fear and intimidation” on set. Warner Bros. announced an investigation, three producers left the show, and Ms. DeGeneres apologized on camera and to employees.

The European Medicines Agency, the European Union’s top drug regulator, whose approval is necessary for countries in the bloc to begin rolling out the coronavirus vaccine, has begun an investigation after it was hit by a cyberattack, it said on Wednesday.

The agency, which is reviewing vaccine candidates, did not provide details about the target or the date of the attack. But shortly after the announcement, Pfizer and BioNTech said in their own statement that some documents related to the regulatory submission of their vaccine and which were hosted on a server of the European agency, had been “unlawfully accessed.”

Pfizer and BioNTech said their systems had not been breached, and that no study participants appeared to have been identified as a result of the cyberattack.

The breach comes at a time of heightened threats faced by pharmaceutical companies, health care institutions and agencies involved in the production, approval and distribution of the vaccine.

Last week, IBM said it had detected a series of cyberattacks in September against companies involved in the distribution of coronavirus vaccines across the world and against a branch of the European Commission, the E.U.’s executive arm.

The European Medicines Agency is set to announce a decision on the Pfizer/BioNTech vaccine by Dec. 29. Although each country in the bloc will be in charge of its own rollout, the agency’s approval will pave the way for the largest vaccination campaign in the West, dwarfing the rollout that started this week in Britain and most likely posing more considerable logistical and security challenges.

Canada approved the Pfizer/BioNTech vaccine on Wednesday, becoming the second Western country to do so. Russia began the rollout of its own Sputnik 5 vaccine on Saturday.

The European Medicines Agency didn’t disclose who was behind the cyberattack, saying that it “cannot provide additional details whilst the investigation is ongoing.” Pfizer and BioNTech said in their statement that they were awaiting further information from the agency.

Cybersecurity experts have said that only state actors could carry out such operations. Microsoft revealed last month that hacker groups backed by Russia and North Korea had targeted several vaccine makers in the United States, Canada and France, among other countries.

“The intentions behind those attacks are to parasite Western efforts on the vaccine,” said Julien Nocetti, a researcher at the French Institute of International Relations who studies cybersecurity with a focus on Russian activities.

By breaking into the system of key actors involved in the vaccine or by disrupting distribution efforts, attackers could exact considerable damage, said Claire Zaboeva, a senior cyberthreat analyst at IBM’s Security X-Force.

Ms. Zaboeva said about the production and delivery of the vaccine: “If you manage to get the key to the whole kingdom, you have 500 options on the menu: collecting key timetables, which nations will get the vaccine, how it will get there, what companies will be associated with the delivery, or how it will be handled.”

Months into the pandemic, many people still are frustrated and confused about virus testing.

Long lines at testing sites, delays in getting results and even surprise testing bills have discouraged some people from getting tested.

And many people don’t understand what a test can and can’t tell you about your risk, and wrongly think a test result that comes back negative guarantees they can’t spread the virus to others.

We asked some of the nation’s leading experts on testing to help answer common questions about how to get tested, what to expect and what the different tests and results really mean.

Among them:

  • When should be people be tested?

  • What are the tests like?

  • What type of test should people get?

  • And how do you interpret the results?

Airlines are just one piece of a massive global machine cranking up to tackle one of the biggest logistical challenges in recent memory.Credit…Kriston Jae Bethel for The New York Times

Months before anyone knew which of the coronavirus vaccine candidates would pull ahead or when they’d be available, airlines were trying to figure out how to transport doses around the world.

Over the summer, American Airlines, Delta Air Lines and United Airlines spoke with government officials, pharmaceutical companies and experts to understand where vaccines might be produced, how they would be shipped and how best to position people and planes to get them moving. More recently, they have flown batches of vaccines for use in trials and research or to prepare for wider distribution.

The industry will play a vital role in moving billions of doses in the months ahead, putting underused planes and crews to work while circulating the very medicine that airlines hope will get people to book tickets again.

“When a request comes in, it’s going to be urgent and we have to act immediately,” said Manu Jacobs, who oversees shipments of pharmaceuticals and other specialty products for United.

One of the biggest challenges for airlines has been ensuring that vaccines are transported at frigid temperatures. Pfizer’s must be stored at an incredibly low minus-94 degrees Fahrenheit. Moderna’s can be kept at a more easily managed minus-4 degrees.

For its vaccine, Pfizer designed special cooler containers that can be stuffed with dry ice, which is solid carbon dioxide. But aviation authorities limit how much dry ice can be carried on planes because it turns to gas, making the air potentially toxic for pilots and crews.

After running tests that showed it was safe, United last month asked the Federal Aviation Administration to raise the limit so it could fly the Pfizer vaccine from Brussels International Airport to Chicago O’Hare International Airport, according to an F.A.A. letter. The agency allowed the airline to carry up to 15,000 pounds of dry ice aboard a Boeing 777-224 plane, compared to the previous limit of 3,000 pounds, according to the letter. A single 777 can carry up to one million doses, the airline said.

In normal times, about half of all air cargo is transported by airlines, often beneath the feet of passengers. The steep decline in flights this spring removed much of that capacity, but the urgent need for masks, gloves and ventilators created a big opportunity for cash-starved carriers, allowing them to recapture at least some of that lost business.

An 83-year-old passenger who initially tested positive for the coronavirus on a “cruise to nowhere” from Singapore this week, forcing thousands of passengers and crew members to return to port a day early, did not have the virus after all, officials said on Thursday.

The passenger, who had diarrhea aboard the ship Quantum of the Seas and had taken a mandatory Covid-19 test, has since tested negative several times, Singapore’s Ministry of Health said in a statement.

“The sample taken from the individual this morning came back negative for the virus,” officials said on Thursday. It was the third negative test after two on Wednesday also came back negative.

Quarantine orders for the man’s close contacts and other passengers aboard the ship were then rescinded, the ministry said.

Singapore’s Tourism Board said that contact tracing began immediately after the man’s positive test and that all leisure activities on board were canceled. The ship’s captain had also ordered guests to remain in their cabins during the investigation.

Quantum of the Seas, which is owned by Royal Caribbean, returned to the Marina Bay Cruise Center in Singapore at 8 a.m. Wednesday. All remaining passengers and crew members were required to undergo mandatory testing upon disembarking, the tourism board said.

The board also asked that passengers monitor their health for 14 days and to undergo a swab test at a designated government center at the end of the monitoring period.

When the cruise left the city-state on Monday, all 1,680 passengers and 1,148 crew members had tested negative for Covid-19, according to the tourism board.

The incident underscores the uncertainties the global tourism industry, battered by the pandemic, faces as it struggles to restart. The cruise ship is one of two to operate out of Singapore this month while putting in place a long list of safety precautions to reassure passengers.

A New York Times reporter recently took a trip on the other one, the World Dream.

In February, the coronavirus infected more than 200 people board the Diamond Princess cruise ship, trapping its 3,600 passengers and crew. Governments later banned cruises, crews were sent home, and passengers canceled their bookings. But countries like Singapore, Japan and several in Europe have since allowed cruises to restart under the watchful eye of officials.

President-elect Joseph R. Biden Jr.’s choice for surgeon general, Dr. Vivek H. Murthy, had a central role in the National Collegiate Athletic Association’s decision in March to cancel this year’s national basketball tournaments — one of the earliest and most culturally significant signs that the virus would upend ordinary life in America.

The work of Dr. Murthy, a member of the association’s powerful Board of Governors who was surgeon general during part of the Obama administration, offers a view into how he approached the pandemic’s initial threat in the United States, and how he might help shape the federal government’s response under Mr. Biden.

A newcomer to the insular world of college athletics, Dr. Murthy proved a cautious, deliberate expert who was wary of making drastic decisions prematurely, interviews with more than a dozen people who participated in the N.C.A.A.’s meetings suggest. But they said that as the tournaments approached and more data and scientific research emerged, Dr. Murthy was a forceful and effective champion of measures that had been unthinkable to most of society only days or weeks earlier.

Indeed, it was Dr. Murthy who urgently told board members that they risked fueling a deadly crisis if they allowed the tournaments to proceed as scheduled.

“He was instrumental in convincing the board that the time to act was now,” said Kenneth I. Chenault, a former chairman of American Express who sits on the N.C.A.A. board.

But board members like Mr. Chenault said that it was plain that Dr. Murthy understood the cultural and financial repercussions of a decision like canceling the basketball tournaments, which generate hundreds of millions of dollars.

GLOBAL ROUNDUP

For most of the year, South Korea has kept its coronavirus numbers so low it was the envy of the world. Now, the country is grappling with the most elusive wave of infections it has seen, just as other nations prepare to roll out vaccinations.

South Korea’s daily number of new cases was once as low as two per day. That number soared to​ 682 on Thursday, with health officials warning it could reach record highs in coming days. On Wednesday​, 686 new cases were reported, the highest daily count since Feb. 29.

“We must exert all we can, considering this is our last hurdle to clear ​in our efforts to curb the coronavirus before vaccines and treatments come online,” President Moon Jae-in said this week. He has instructed his government to mobilize ​​soldiers​, police officers and civil servants ​to help epidemiologists’ contact-tracing efforts.

The country’s struggle to contain the recent surge is a race against time. Mr. Moon’s government announced this week that it had secured enough doses of coronavirus vaccines from companies like AstraZeneca and Pfizer to inoculate roughly 86 percent of the population, but that the first batch would not arrive until March.

South Korea has been hit by four waves of infections since its first case was reported in January. But the latest is by far the ​hardest to control, health officials said.

Previous waves included mass clusters that health officials were able to target and trace. The current wave spread through numerous small clusters that erupted in nursing homes, hospitals, saunas, bars, restaurants, music halls and factories, most of them in the Seoul metropolitan area, but also in towns farther away.

Daily cases continue to rise despite tightened social-distancing ​guidelines and other measures. Na Seong-woong, a deputy commissioner of the Korea Disease Control and Prevention Agency, warned that the daily caseload could surpass 900 next week.

“We are facing our biggest ever coronavirus crisis because the current wave is neither temporary nor regional, but steady and nationwide,” he said. “We don’t have one central cluster that we can shut down with a focused testing and isolating campaign, but it’s popping up here and there and everywhere through our daily lives.”

In other developments across the world:

  • Spain was hit far worse during the first wave of the coronavirus than official data showed at the time, according to new statistics published by Spain’s national statistics institute on Thursday. The institute said 45,684 people had died of Covid-19 between March and May, compared to the 27,127 dead that Spain’s health ministry had reported by May 31. The health ministry counts only deaths officially attributed to Covid-19, while the statistics institute counted those who died with the disease as the most likely cause.

  • Hospitals in Tokyo were strained as Japan’s capital city reported 602 new cases on Thursday, its first time topping 600 cases in a day, officials said. Government officials have recommended that residents avoid outings.

  • Pope Francis will hold midnight Mass in Rome two hours earlier on Christmas Eve than he has in previous years, beginning at 7:30 p.m. to comply with Italy’s 10 p.m. curfew. The pope will also give his annual Christmas Day blessing at noon from inside St. Peter’s Basilica instead of from the loggia, where thousands would usually gather.

  • Secondary school students in the seven worst-hit areas of London will be tested for the virus, Britain’s health secretary, Matt Hancock, said at a news conference on Thursday evening. Mr. Hancock said that group of students, which he described as being ages 11 to 18, is by far accounting for the fastest rise in cases, and that the virus rate among adults in London is “broadly flat.” He urged secondary school students to get tested regardless of whether they had symptoms and said more details on the plan would follow Friday. Mr. Hancock said with the vaccine now being administered in Britain, there is hope on the horizon. “So don’t blow it now.”

  • In New York City, Mayor Bill de Blasio outlined a plan on Thursday, without providing much specific detail, to help students recover from the educational disruption caused by the pandemic. “Clearly, there will be a Covid achievement gap, and we have to close that,” he said. The mayor noted several areas he would focus on before the start of the next school year in September: finding a baseline for the academic ground lost; developing digital content and a learning hub; expanding professional development; enlisting parents to help more in education; and helping students deal with mental health issues and trauma related to the pandemic.

The French government on Thursday said that it will delay relaxing some Covid-19 lockdown restrictions because rates of new cases were not falling as fast as expected.

The reopening of theaters, museums and cinemas, which was planned for Dec. 15, will be pushed back another three weeks, and a curfew that will replace the current lockdown will run earlier than planned.

The authorities had announced that a reprieve from the restrictions would be implemented on the condition that France reached a target of 5,000 new cases per day and fewer than 3,000 Covid-19 patients in intensive care.

Although the target of 3,000 patients in intensive care is within sight, France on Wednesday reported about 15,000 new cases, dampening hopes that daily new cases could fall to 5,000 by next Tuesday.

“We are not yet at the end of this second wave and we will not reach the objectives we had set,” Prime Minister Jean Castex said at a news conference on Thursday.

“The battle is far from won,” he said, adding that although the health situation improved for the past few weeks, it has plateaued in recent days.

The health minister Olivier Véran said that “we know that from plateau to peak sometimes things can go very fast.”

France will stick to a previously announced plan to end the lockdown on Dec. 15 and replace it with a nightly curfew. But in a departure from the plan, the curfew will start one hour earlier, at 8 p.m., and will not be waived for New Year’s Eve.

An exception will be made for Dec. 24, Christmas Eve, when people will be allowed to move freely during the night.

“The risk is that if we don’t change anything, the second wave will start again in the next few weeks,” Mr. Véran said.

On Thursday, the French Senate released a scathing report of a parliamentary commission that dissected the government’s failures in its handling of the coronavirus crisis and denounced “late and uncoordinated decisions” that delayed the government’s response to the pandemic.

The report specifically pointed to the failure of the government’s management of critical stocks of face masks. “The shortage of masks will remain the unfortunate symbol of the unpreparedness of the country and the lack of anticipation of the health authorities in the face of the crisis,” the report said.

It pointed out that Jérome Salomon, a top official at the health ministry, chose not to replenish stocks of masks in 2018, despite being warned about risks of shortages, and lobbied to retrospectively amend a scientific report in order to justify this decision. In a statement sent on Thursday night, Mr. Salomon denied that any pressure was exerted on the authors of the report.

“The mask fiasco was deliberately concealed by the government during the crisis,” the report said, adding that “a communication crisis has undermined the credibility of public and scientific discourse, the effects of which will be lasting.”

The parliamentary commission added that France’s strategy to test, trace and isolate in order to prevent a second wave of the virus proved unsuccessful, because of backlogs of test results, a limited contact tracing operation and an almost nonexistent isolation strategy.

Mr. Castex did not comment on the report, but acknowledged that a sense of fatigue surrounding the pandemic was growing in the country.

“I know your weariness, your doubts, your suffering,” Mr. Castex said. “I share them.”

Staff aides to Senate Majority Leader Mitch McConnell warned that most Republicans are unlikely to support the bipartisan plan.Credit…Anna Moneymaker for The New York Times

Staff aides to Senator Mitch McConnell of Kentucky, the majority leader, have informed other congressional leaders that it is unlikely that the majority of Republicans could support compromise provisions addressing liability protections and state and local government funding in a $908 billion stimulus deal being hammered out by a bipartisan group of moderates.

Their warning reflected the deep resistance among several Republicans for another large round of federal relief. For months their reluctance has helped to stymie agreement on an economic recovery plan to help struggling businesses and individuals amid the pandemic. Mr. McConnell and Republicans have been particularly resistant to providing billions of dollars to cash-strapped state and local governments, a top Democratic priority that would receive $160 billion under the moderates’ emerging outline.

That package is likely to contain some form of limited liability protection to businesses, schools and hospitals, which most Democrats have dismissed as a nonstarter, but the shield could be temporary and not as sweeping as the one that Mr. McConnell has demanded, which prompted the private skepticism.

The potential Republican antipathy for the compromise that was conveyed by Mr. McConnell’s staff was first reported by Politico, and was relayed on condition of anonymity by a senior Democrat familiar with the conversation. Mr. McConnell’s office declined to comment.

“My view is that the best thing that could happen is the pieces of this that everybody agrees on, take that out — take the funding for state local governments out — and pass the rest of it,” Senator John Thune of South Dakota, the No. 2 Republican, told reporters, offering a suggestion Democrats have panned.”

The bipartisan group is still struggling to finalize its agreement, let alone produce legislation that could be voted on in the coming days.

With just a handful of days before the end of the 116th Congress and a number of critical programs established in previous coronavirus legislation set to expire, lawmakers agree that both chambers should not leave Washington until they reach consensus on both an omnibus government spending package and a pandemic aid deal.

The Senate is expected to approve a one-week stopgap bill before funding lapses on Friday, intended to buy additional time for negotiators on both issues. But the timing of the vote was unclear as of Thursday afternoon.

Top Democrats have signaled support for the bipartisan discussions, led by a handful of moderate lawmakers in both chambers, as a possible avenue for a final agreement. But in doing so, Democrats also rejected a proposal from Mr. McConnell to remove the provisions related to state and local government and liability protections and focus on approving funding for schools, education and small businesses.

Steven Mnuchin, the Treasury Secretary, presented Ms. Pelosi on Tuesday with a $916 billion alternative, but she and other Democrats rejected it given that it failed to revive lapsed federal supplemental jobless payments. Instead, it would include a round of $600 stimulus checks, half the amount initially approved earlier this year.

ABNB begins buying and selling on the Nasdaq

The NASDAQ market page will display an AirBnb sign on their billboard on the day of their IPO in Times Square in the Manhattan neighborhood of New York City, New York, United States, on December 10, 2020.

Carlo Allegri | Reuters

Airbnb is set to double its share price by its IPO debut on Thursday at the latest in a wave of hotly anticipated tech IPOs in a year that has been tumultuous due to the pandemic.

The shares were priced at $ 68 on Wednesday and are expected to hit around $ 152.30 when the stock starts trading, according to early signs prior to initial trading. Airbnb is traded on the Nasdaq under the ticker “ABNB”.

The stock is expected to trade between 12:30 p.m. and 1:00 p.m. Eastern Time, a well-placed source CNBC’s Leslie Picker said. Speculation that it would join one of the major indexes in the next few years seems to be sparking interest, the source said.

The company is going public at a time when the sector was hit by reduced travel trends during the public health crisis. Revenue last quarter was down nearly 19% to $ 1.34 billion year over year. But it still managed to make a profit of $ 219 million, and there were other intermittently profitable quarters as well.

While travel was less, Airbnb managed to find a sweet spot for those willing to hit the road who prefer home stays over traditional hotels. That could change when vaccines make travel more accessible again, possibly as early as late next year.

Airbnb’s CEO Brian Chesky said in an interview with CNBC’s Deirdre Bosa on the Thursday ahead of its IPO that the platform is considering changing the way travelers want to plan their trips as remote working is an option for many.

“Now that people come to Airbnb, they don’t even necessarily have a destination or dates in mind because they’re flexible. We’re all obviously zoomed in, and that’s why people say, ‘I want to go anywhere 300 miles around me around, what can you show me? ‘”he said. “Now we’re going to dig a little more into the game of inspiration and tune people into the perfect home experience for them.”

Chesky also said he wasn’t too concerned about the rating.

“I don’t think I’ll be more concerned than I did in April and May when our business fell 80% in eight weeks in the middle of a pandemic,” he said.

Airbnb struggled with complaints from hosts on its platform at the beginning of the pandemic, when the company indulged guest cancellations, leaving hosts with no expected payments. A Texas-based host filed a class action lawsuit against the company last month alleging that Airbnb breached its contract with hosts by offering the refunds. Airbnb called the lawsuit “frivolous and without merit” in a statement at the time.

As part of its IPO, Airbnb set up a Host Endowment Fund made up of 9.2 million non-voting shares. Airbnb said in its IPO prospectus that the fund would benefit hosts through programs and grants.

“We want hosts to share in our success, not just for a moment, but as long as Airbnb exists in the world,” the company wrote. “We intend that the Host Endowment Fund will be a long-term investment in the future of our hosting community, built by hosts for hosts.”

Airbnb was listed eight times on CNBC’s annual Disruptor 50 list and ranks 41st in 2020 Disruptor 50 companies.

It’s Australia’s First Huge Blaze of the Fireplace Season. How Unhealthy Will the Summer time Get?

SYDNEY, Australia – The first big fire of the Australian forest fire season has now blackened roughly half of Fraser Island, an idyllic haven north of Brisbane known for its golden beaches and abundant biodiversity.

With evacuation orders reaching residents on Monday, Australians who had hoped there wasn’t much to burn after last year’s colossal fires are now fighting with a brutal reminder: In a vast country that is at risk of fire and particularly vulnerable to The risk of record-breaking infernos never goes away.

In fact, it continues to increase.

“I’m sure it’s a hit for us and everyone watching,” said Jack Worcester, 34, whose family owns Cathedrals on Fraser, a campground that was recently evacuated. “There is currently no normal for a fire season – any fire season can be pretty serious.”

At this point last year, desiccated forests outside Sydney had been burning for weeks, covering the city’s sky with an orange-gray haze. But while this year (so far) feels less overwhelming, one question hangs on the mind of many Australians, and it’s the same question the Californians asked a few months ago and will be asking again next year: How bad is it going? to get?

Fires are usually measured and recorded using hard statistics – acres burned, homes and lives lost – but before counting there is an impressionistic mapping of the risk, shaped by terrain, climate, human activity and chance.

This year’s Australian seasonal prospect maps show a broad red amoeba for areas of above-average danger that run through the grassy plains of central New South Wales, the southeastern state of which Sydney is the capital. But you have to dig deeper to see that many other areas are also at risk.

For example, Fraser Island is marked as “Normal Fire Potential”. The fire that is now burning, pulling firefighters ashore and on planes to put out the flames and close the island to visitors, is believed to have been caused by an illegal bonfire lit by tourists on October 14th has been.

“By and large, fire is a natural part of the Australian landscape. Even if we say the year has normal or below average risk, it doesn’t mean there is no risk, ”said Naomi Benger, climatologist with the government’s Bureau of Meteorology. “It means the risk is as high as in an average year.”

Due to climate change, she added, the average risk of fire is increasing.

“It only takes a day or two to be disastrous,” she said. “People shouldn’t be complacent.”

La Niña, a large change in tropical Pacific temperatures that affects global weather patterns, is the dominant factor in the 2020-21 Australian fire season. La Niña brings cooler water closer to the ocean surface in the central and eastern tropical Pacific, and this year has provided above-average rainfall for most of the country.

Thunderstorms and long spring weeks have filled the reservoirs, relieving farmers in New South Wales and Queensland after many years of drought. But the soaked rains have also created fields of grass in the plains west of the Great Dividing Range, the mountain range that runs up and down the east coast of Australia.

With just a few hot, dry days, these grasses turn green to brown, making them as easy to light as a dry piece of paper, maybe even easier. This creates a particularly unpredictable and deadly danger.

“The main difference is the intensity; Grass fires are less intense than forest fires in general, but they spread very, very quickly, ”said Richard Thornton, who heads the Cooperative Research Council on Bushfires and Natural Hazards and makes the maps that most countries use to assess each fire base season. “They are certainly moving faster than you can run or walk in front of them, and they are very much dominated by the wind.”

In 1969, a dozen grass fires near the town of Lara killed 23 people, including 17 trapped in their cars on the highway. Some of them tried to escape the fire and failed.

Grass fires also generate enormous amounts of radiant heat. When willow trees caught fire along the surrounding woods in Batlow town in January, the heat from the flames in the grass melted some of the fire trucks and firefighter helmets.

“Because they can move quickly and change direction quickly, people can easily be caught and overrun by a grass fire,” Thornton said. “We’ve seen it before.”

La Niña is just one factor among many. Other weather forces have created drier than normal conditions in places like tropical Queensland.

Fraser Island saw fewer thunderstorms than usual in November, and these dry conditions were exacerbated by the heat. Last month was Australia’s hottest November ever. Projections also suggest that December through February maximum temperatures in parts of southeast and western Australia and along the Queensland coast will likely be above the long-term mean.

That means a higher risk. The onset of a heat wave or two or three this summer could dry out many areas and make fires even more difficult to fight.

Scientists argue that this is climate change in action. As global average temperatures have risen by one degree Celsius since the pre-industrial era, variability in weather patterns is increasing, particularly in Australia, the world’s driest inhabited continent.

What once looked like an anomaly can quickly become the new normal.

“With the Australian fire season last year combined with that in California last year, it can be said that this is what the future will be because of climate change,” said Thornton. “Last year’s fires were unprecedented, but they are no longer like that. Now that we’ve had these fires, they have to be part of the planning. “

A recent report by an independent Royal Commission on fires last year recognized that climate change had already significantly increased the risk of natural disasters in Australia. Numerous changes to fire fighting in the country have been recommended, calling for more aircraft and better coordination of data and communications equipment.

Very little of what the Commission requested has been put into practice or even approved. Prime Minister Scott Morrison goes on to claim that his administration’s efforts to combat climate change – widely viewed as overwhelming and weak by climate researchers in the country – are sufficient.

Emergency managers say the bigger challenge, whether in the US or Australia, is getting the general population in fire-prone areas to understand the changing environment and the risks.

“It’s hard,” said Mr. Thornton. “You don’t want to face the fact that your place of residence is risky.”

Until they can see the fire and the smoke.

Mr. Worcester, the campsite owner on Fraser Island, said that at one point he was exposed to flames close enough for a rock to reach.

“I stood on our property during the ceasefire and watched it be less than 100 meters north of us,” he said. “It was 15 meters tall.”

He said he now intends to buy his own personal fire fighting equipment “just to calm down”. And yet, he already knows that the relief will be short-lived.

The campsite, which was 40 percent full when it had to be evacuated and is now being asked to cancel reservations left and right, is surrounded on three sides by bushland, with the sea in front.

“The vegetation will have grown beyond what it was this year,” Worcester said. “We’ll have two or three years less risk, then another eight years of high risk.”

“At the end of the day,” he added, “when it’s really serious, there is only so much you can do.”

Joe Biden son Hunter Biden beneath federal tax investigation

“I take this matter very seriously, but I am confident that a professional and objective review of these matters will show that I have handled my affairs legally and appropriately, with the benefit of professional accountants,” said Hunter Biden.

Hunter Biden, an attorney whose late brother Beau Biden was the Delaware attorney general prior to his death, did not reveal any further details of the investigation.

Kim Reeves, a spokeswoman for David Weiss, the US attorney for Delaware, said in an email, “Per DOJ [Department of Justice] We cannot comment on politics on an ongoing investigation. “

CNN reported later Wednesday that it had reached out to Hunter Biden’s attorney and his father’s presidential campaign last week for comment on the investigation. CNN reported that “several financial issues are being investigated, including whether Hunter Biden and employees have broken tax and money laundering laws in doing business in foreign countries, primarily China.”

CNN reported that the investigation had been “largely dormant for the past few months” as the Justice Department issued regulations prohibiting legal action in cases that could affect an election.

Publicly available documents show Hunter and his ex-wife Kathleen Buhle had a lien on unpaid taxes, possibly including interest and penalties totaling $ 112,805.09, as of March this year, NBC News reported. Documents submitted by the IRS show that the lien was issued in November 2019. It is not immediately clear whether the lien has anything to do with the investigation.

The New York Post reported in October that in December 2019 the FBI seized both a computer and hard drive believed to have been made by Hunter Biden after the owner of a computer repair facility in Wilmington, Delaware, told federal authorities that he was in possession of these items.

The shopkeeper gave a copy of the hard drive to an attorney for Rudy Giuliani, President Donald Trump’s personal attorney, the Post reported. Giuliani then gave the newspaper a copy of the hard drive.

In a statement on Wednesday, the transition team of Democrat Joe Biden and Vice President-elect Kamala Harris said: “President-elect Biden is deeply proud of his son who has faced difficult challenges including the vicious personal attacks of the past few months. “

The White House and the US Department of Justice, which oversees US law firms, declined to comment.

Hunter Biden has long struggled with drug addiction and other personal problems.

He was despised in court earlier this year for failing to provide financial information to an Arkansas woman who said she had given birth to his child.

This woman’s attorneys, Lunden Alexis Roberts, said in January that Hunter Biden failed to meet a court-ordered deadline for submitting documents five years ago as part of her application for child support for her then 16-month-old wife Child.

These documents included “a list of all sources of income”, copies of tax returns and a list of companies in which he is involved, court records showed.

Hunter Biden, who initially claimed he never had sex with Roberts, later stopped denying that he was the child’s father.

He closed the case with Roberts in March by agreeing to pay her an undisclosed amount each month for child support and agreeing to maintain health insurance for the child. He also agreed to pay Roberts an undisclosed amount of money, which apparently included her attorney’s fees and expenses.

During the presidential election, Republican Trump and his allies made Hunter Biden a focus of political attack, particularly related to his business dealings in Ukraine and China.

Hunter Biden and his father have denied any wrongdoing related to their overseas business in which Joe Biden was not a part.

Trump, who refuses to admit he lost the election, was charged by the House of Representatives last year for withholding Congress-appropriated military aid to Ukraine when he pressured the nation’s new president to investigate the Biden. Trump was acquitted after a trial by the Senate.

In an interview last week, Joe Biden told CNN that once he took office, he would not try to influence Justice Department decisions.

“It’s not my Justice Department. It’s the People’s Justice Department,” Biden said.

He also said the department “can independently decide who will and who will not be prosecuted”.

The investigation into Hunter Biden comes after Trump’s firm, the Trump Organization, is under criminal investigation by the Manhattan Attorney’s Office for explaining hush payments to women who claim they have sex with Trump. The president has denied having sex with a woman, porn star Stormy Daniels and Playboy model Karen McDougal.

The DA office could also investigate possible tax crimes as well as banking and insurance fraud, as suggested by court records.

Trump is currently battling DA Cyrus Vance Jr.’s efforts to get eight years worth of tax returns and other financial records from the President from his longtime accountants.

At the same time, the New York attorney general’s office is conducting a civil investigation for possible misstatements about the value of Trump Organization real estate. The President’s son, Eric Trump, was recently questioned by investigators from the AG’s office as part of this investigation.

Trump’s daughter Ivanka Trump, a senior White House adviser, was dismissed last week on a lawsuit by the Attorney General in Washington, DC. This AG accuses the Trump Organization, the Trump Inaugural Committee and the Trump International Hotel in this city of “openly and unlawfully misused charitable funds to enrich the Trump family” in connection with the expenditures for the inauguration of Trump 2017 .

According to research by The New Yorker, ProPublica and WNYC, Ivanka Trump and her other adult brother Donald Trump Jr. narrowly avoided criminal charges by Vance’s office in connection with the marketing of the Trump SoHo Hotel in New York in 2012. Vance’s office had investigated whether potential buyers had been misled about the success of the project.

The outlets reported that Marc Kasowitz, an attorney for Ivanka and Donald Jr., donated $ 25,000 to Vance’s re-election campaign and appealed directly to him to drop the case.

Iran Claims Arrests in Killing of High Nuclear Scientist

Iranian authorities have arrested a number of people allegedly involved in the murder of the country’s top nuclear scientist last month near Tehran, a parliamentary adviser told an Iranian state broadcaster on Wednesday.

The adviser, Hossein Amir Abdollahian, did not say how many people had been arrested in connection with the death of scientist Mohsen Fakhrizadeh and did not reveal their identity, according to Al Alam News Agency.

“Those involved in this attack, some of whom have been identified and even arrested by security services, cannot escape the judiciary,” said Abdollahian, a former deputy foreign minister who is now an adviser to the President of Parliament. after a transcript of the interview. He added that the authorities would “react firmly to them and make them regret their actions”.

According to American and Israeli officials, Fakhrizadeh was seen as the driving force behind Iran’s secret nuclear weapons program, and the brazen assassination left Tehran in shock and embarrassment. The scientist was ambushed on a country road, although conflicting reports about the conduct of the assassination exposed tensions between rival factions in the Iranian government as each tried to shift the blame.

Shortly after the murder, at least three officials said Israel was behind the attack, and since then Israeli officials have all but publicly acknowledged the responsibility.

It remained unclear how much the United States might have known about the operation in advance, but the two allies have long exchanged information about Iran, particularly its nuclear program.

Mr Abdollahian said that the Iranian authorities believed the Israelis had help coordinating the assassination of Mr Fakhrizadeh, adding “there is no doubt” that there was also American involvement.

Girls are very important to attaining world ‘monetary inclusion’

Women are vital to making sure finance – and financial education – gets to other parts of society, said billionaire philanthropist Bill Gates.

Governments and corporations serious about giving all members of society access to financial services should focus their resources on women, the Microsoft co-founder said at the Singapore FinTech Festival on Tuesday.

“It’s absolutely critical,” notes Gates, noting that women are usually responsible for family support finances.

“The benefits of getting the money under their control mean that it is more likely to be used for nutrition and education and for things that lift this family out of poverty,” he said at this year’s virtual conference.

Global improvement in inclusivity

Financial inclusivity, which refers to giving more people access to financial services, remains a key challenge for communities around the world.

Only 35% of people in low-income countries have access to a bank account. According to the World Economic Forum, this is 58% to 73% in higher to lower middle income countries and 94% in high income countries. These values ​​are lower in women.

It is important to remember how far we are from universal financial inclusion.

Founder, Bill & Melinda Gates Foundation

The pandemic has only made this shortage apparent as governments struggled to provide financial aid to those most in need while in lockdown across the country.

“You know, it’s important to remember how far we are from universal financial inclusion,” said Gates.

Invest in digital solutions

Through his nonprofit, the Bill and Melinda Gates Foundation, Gates has worked with governments and central banks for several years to improve financial inclusion in developing countries.

In particular, this included the introduction of digital solutions, which Gates says can help such countries catch up with or possibly overtake advanced countries with existing legacy systems.

“We spend a lot of our time with central bankers making sure they see what the pioneers did,” said Gates.

There is almost an easy way they can connect their citizens.

To that end, the foundation is funding digital identity solutions such as MOSIP in India, an openly accessible software that allows governments to create digital identities for their citizens to help distribute resources. According to Gates, the acceptance of such technologies has so far been high in countries from Nigeria and Ethiopia to Indonesia.

“We believe that most central banks will say in the next five years that they can do this because most of the building blocks are accessible and it is almost easy to connect their citizens,” he said.

Gates said his foundation aims to fund two-thirds of the world’s population within a decade.

Britain rolls out the Pfizer vaccine, an enormous process however an indication of hope.

The UK’s National Health Service delivered its first footage of the Pfizer BioNTech Covid-19 vaccine on Tuesday. He opened a mass vaccination campaign with little precedent in modern medicine, making the British the first in the world to receive a clinically approved, fully tested vaccine for the disease.

Vaccine centers across the country are starting to carefully deliver vaccinations on a tight schedule, as the vaccine must be used or thrown away within five days of being thawed. “We do this with military precision, and indeed the military helped us with our planning,” said Fiona Kinghorn, who oversaw the launch of the vaccine at a site in Cardiff, Wales.

The effort marks a turning point in the remarkable race to manufacture a vaccine and global effort to end a pandemic that killed 1.5 million people worldwide. At a Welsh vaccination center, a retired nurse on the facility described the reaction of her youngest patient, another nurse. “She just cried and said it was such an emotional day,” she said, adding, “I think partly because she worked on a Covid ward so she saw the consequences and probably the results. Me assume she saw a lot. “

At 6:31 am Tuesday, 90-year-old Margaret Keenan, a former jeweler, rolled up the sleeve of her Merry Christmas T-shirt for the first shot, and her image quickly became a symbol of hope and resilience .

“I feel so privileged to be the first person to be vaccinated against Covid-19,” said Ms. Keenan, who lives in Coventry, Central England. “That means I can finally look forward to spending time with family and friends in the New Year after being alone for most of the year.”

UK regulators jumped ahead of their American counterparts last week to approve a coronavirus vaccine, which angered the White House and sparked a lively debate over whether the UK had moved too quickly or whether the United States was wasting valuable time when the virus was around 2,200 People killed Americans one day in the past week, as of Monday.

President Trump planned on Tuesday to issue an executive order proclaiming that other nations will not receive US vaccines until after Americans are vaccinated. This guideline seemed to have no real teeth, but it was indicative of the heated race to secure dose deliveries.

For the people who were vaccinated in the UK, including doctors and nurses who joined the country’s National Health Service this year, the footage was an early glimpse into life after the pandemic. Except for Ms. Keenan, none got as much attention as William Shakespeare, who was second in a shot in Coventry and whose real name, the National Health Service confirmed, is William Shakespeare. Twitter used the news of his vaccination as an opportunity for an enthusiastic play on words and jokes about the taming of the flu and the gentlemen of Corona.

“Today is a great day for medicine and the future,” said Chris Whitty, chief medical officer for England, on Tuesday. (A previous version of this article incorrectly stated that he was the chief medical officer for the whole of the UK.)

The first 800,000 doses of Pfizer BioNTech vaccine for the UK have been shipped from a manufacturing facility in Belgium to government warehouses in the UK and then to hospitals in the past few days.

50 hospitals will manage the admissions until the government can refine a plan for delivery to nursing homes and doctor’s offices. The vaccine must be transported in temperatures similar to the south pole before it can be stored in a regular refrigerator for five days, Pfizer said. Doctors and nurses, certain people aged 80 and over, and nursing home workers are given the vaccine first.

Some doctors and nurses have received invitations to register for appointments in the past few days. The first shots are for those who are at the highest risk of serious illness. The government has indicated that people aged 80 and over who have already had a doctor’s visit or are discharged from certain hospitals for this week will also be among the first to receive gunfire.

Nursing home residents, who should actually be the government’s top priority, will be vaccinated in the coming weeks once health officials start distributing doses across hospitals.

Hundreds of people are still dying from the virus every day in the UK, and the country has taken into account Christmas travel that scientists fear will trigger another surge in infections.

“It’s amazing to see the vaccine, but we can’t afford to relax right now,” British Prime Minister Boris Johnson said Tuesday morning when visiting a London hospital. Trying to calm a recipient’s nerves over needles, he suggested, “I always try to think of something else – recite poetry.”

Ms. Keenan, the first vaccine recipient, showed no such nerves. Nicola Sturgeon, Scotland’s first minister, said on Twitter that she had “a little lump in her throat” when Ms. Keenan was shot.

“Feels like a milestone after a tough year for everyone,” added Ms. Sturgeon.

Ms. Keenan’s shot was administered by May Parsons, a nurse originally from the Philippines who has worked for the National Health Service for 24 years.

“The past few months have been difficult for all of us who work in the NHS,” she said, “but now it feels like there is light at the end of the tunnel.”

Apple could take away apps that observe customers with out permission in 2021

Craig Federighi, Apple’s senior vice president of software engineering, speaks during a new product announcement at the Apple Worldwide Developers Conference on Monday June 4, 2018 in San Jose, California.

Starting next year, Apple will be removing apps from its app store that are tracking users without prior permission. This promises to strengthen iPhone users’ privacy but is likely to shake the app advertising industry.

To target advertisements and measure their effectiveness, app developers and other industry players currently often use an IDFA (Identifier for Advertisers) or a sequence of letters and numbers that is different on each Apple device.

In an update to the iPhone operating system, which is expected “early next year,” app manufacturers must ask for permission to access a user’s IDFA via a popup. A significant proportion of users will likely choose to opt out, which will reduce the effectiveness and profitability of targeted ads. The change takes a privacy option that was previously buried in Settings and brings it to the fore when users open each app.

On Tuesday, Craig Federighi, Apple’s senior vice president of software development, said apps that do not meet the new requirements that Apple calls App Tracking Transparency (ATT) can be removed from the App Store. This is the only way to install software on an iPhone.

The move puts app developers who make money from targeted ads versus Apple, which has increasingly built privacy features into its products to set them apart from the competition. Among the critics is Facebook, which said the change could cut sales in one of its advertising stores by 50%.

“Some in the advertising industry are opposing these efforts, claiming that ATT will cause ad-supported businesses to suffer dramatic damage. However, as with the introduction of intelligent tracking prevention, we expect the industry to adapt and deliver effective advertising without invasive tracking “said Federighi in a speech at a European data protection conference.

Some examples of the tracking that Apple says app makers would need to get user permission first:

  • Show targeted advertisements in apps based on user data collected from apps and websites of other companies.
  • Share device location data or email lists with a data broker.
  • Share a list of emails, promotional IDs, or other IDs with a third-party ad network that will use the information to refocus those users in other developer’s apps or find similar users.

“Early next year we will need any apps that want to do this in order to get explicit permission from their users, and developers who do not meet this standard can have their apps removed from the App Store,” said Federighi.

The disclosure that Apple can remove non-compliant apps also raises the stake for a date expected early next year when app developers will have to specifically ask permission to use IDFA to perform tracking, forcing developers to rebuild part of their ad targeting systems to meet Apple’s requirements.

According to StatCounter, Apple’s iPhones make up just over 25% of smartphones worldwide, but the market share is higher in countries like the United States. In addition, iPhone users are often wealthier and viewed as more valuable customers. When app developers are removed from the app store, they lose a huge market.

Apple’s ATT is the latest in a series of steps reducing advertisers’ ability to collect data about iPhone users. In 2017, Apple introduced a feature called ITP that uses machine learning to block ad trackers in the Apple Safari browser. On Tuesday, Apple asked app developers to submit a detailed questionnaire about its privacy practices and the data they and third-party partners collect before being approved on the App Store.

Apple has been criticized on both sides of the IDFA issue. In France, advertising firms and publishers filed a competition complaint in October alleging that the proposed move away from IDFA is using privacy as cover for anti-competitive behavior to harm smaller tech companies.

Last month, Apple was also hit by complaints from activists in Europe that IDFA – the current system – did not comply with European data protection laws.

“We have postponed the release of ATT until early next year to give developers the time they have given to properly update their systems and data practices. However, we are still fully committed to ATT and our comprehensive approach to privacy obliged, “said Jane Horvath, senior data protection officer at Apple, replied.

Apple has not publicly announced when ATT will take effect.

‘Go for It’: U.K.’s First Vaccine Patient Encourages Others

Margaret Keenan, the first patient in Britain to receive the coronavirus vaccine, hopes to set an example for people hesitant to get vaccinated.

It was fine, it was fine. I wasn’t nervous at all. It was really good. “And what do you say to those who might be having second thoughts about this?” Well, I would say go for it. Go for it, because it’s free and it’s the best thing that’s ever happened, at the moment. So, do please go for it. That’s all I’ll say, you know. If I can do it, well, so can you.

Britain’s National Health Service delivered its first shots of the Pfizer-BioNTech Covid-19 vaccine on Tuesday, opening a mass vaccination campaign with little precedent in modern medicine and making Britons the first people in the world to receive a clinically authorized, fully tested vaccine for the disease.

Across the nation, vaccine centers are beginning the careful process of delivering vaccinations on a tight schedule, as the vaccine must be used or discarded within five days of being defrosted. “We’re doing it with military precision, and in fact, we have had the military helping with our planning too,” said Fiona Kinghorn, who oversaw the vaccine rollout at one site in Cardiff, Wales.

The effort marks a turning point in the remarkable race to produce a vaccine and the global effort to end a pandemic that has killed 1.5 million people worldwide. At one Welsh vaccination center, a retired nurse on the facility staff described the response by her most recent patient, another nurse. “She just cried and said this was such an emotional day,” she said, adding: “I think partly because she worked on a Covid ward, so she has seen the consequences and probably the outcomes. I presume she has seen a lot.”

At 6:31 a.m. Tuesday, Margaret Keenan, 90, a former jewelry shop assistant, rolled up the sleeve of her “Merry Christmas” T-shirt to receive the first shot, and her image quickly became an emblem of hope and resilience.

“I feel so privileged to be the first person vaccinated against Covid-19,” said Ms. Keenan, who lives in Coventry, in central England. “It means I can finally look forward to spending time with my family and friends in the new year after being on my own for most of the year.”

British regulators leapt ahead of their American counterparts last week to authorize a coronavirus vaccine, upsetting the White House and setting off a spirited debate about whether Britain had moved too hastily, or if the United States was wasting valuable time as the virus was killing about 2,200 Americans a day over the last week, as of Monday.

President Trump planned on Tuesday to issue an executive order proclaiming that other nations will not get U.S. supplies of its vaccine until Americans have been inoculated, a directive that appeared to have no real teeth but nevertheless was indicative of the heated race to secure shipments of doses.

For the people receiving vaccinations in Britain, among them doctors and nurses who have fortified the country’s National Health Service this year, the shots were an early glimpse at post-pandemic life. Besides Ms. Keenan, none attracted as much attention as William Shakespeare, who was second in line for a shot in Coventry and who, the National Health Service confirmed, really is named William Shakespeare. Twitter took the news of his vaccination as an opportunity for delighted wordplay, cracking jokes about the Taming of the Flu and the Gentlemen of Corona.

“Today is a great day for medical science, and the future,” Chris Whitty, the chief medical officer for England, said on Tuesday. (An earlier version of this item mistakenly said he was the chief medical officer for all of Britain.)

The first 800,000 doses of the Pfizer-BioNTech vaccine for Britain were transported in recent days from a manufacturing plant in Belgium to government warehouses in Britain, and then to hospitals.

Fifty hospitals will be administering the shots until the government can refine a plan for delivering them at nursing homes and doctor’s offices. The vaccine must be transported at South Pole-like temperatures before it can be stored for five days in a normal refrigerator, Pfizer has said. First to receive the vaccine will be doctors and nurses, certain people aged 80 and over, and nursing home workers.

Some doctors and nurses have received invitations in recent days to sign up for appointments, with the first shots intended for those at the highest risk of severe illness. The government has indicated that people aged 80 and over who already have visits with doctors scheduled for this week, or who are being discharged from certain hospitals, will also be among the first to receive shots.

Nursing home residents, who were supposed to be the government’s top priority, will be vaccinated in the coming weeks, once health officials start distributing doses beyond hospitals.

Hundreds of people are still dying in Britain each day from the virus, and the country has made allowances for travel over the Christmas period that scientists fear will seed another uptick in infections.

“It is amazing to see the vaccine, but we can’t afford to relax now,” Prime Minister Boris Johnson of Britain said on Tuesday morning as he visited a London hospital. Trying to calm a recipient’s nerves about needles, he suggested, “I always try to think of something else — recite some poetry.”

Ms. Keenan, the first vaccine recipient, showed no such nerves. Nicola Sturgeon, Scotland’s first minister, said on Twitter that watching Ms. Keenan receive the shot gave her “a bit of a lump in the throat.”

“Feels like such a milestone moment after a tough year for everyone,” Ms. Sturgeon added.

Administering Ms. Keenan’s shot was May Parsons, a nurse who is originally from the Philippines and has worked for the National Health Service for 24 years.

“The last few months have been tough for all of us working in the N.H.S.,” she said, “but now it feels like there is light at the end of the tunnel.”

The University of Oxford published a much-anticipated paper on Tuesday detailing the findings of its coronavirus vaccine trials, echoing results first announced two weeks ago that showed the vaccine had 70 percent efficacy on average across two different dosing regimens.

But while it was the first peer-reviewed publication outlining late-stage results of a leading coronavirus vaccine, it did little to answer the most pressing questions facing the university and AstraZeneca, the drug maker, since they offered a glimpse at the same promising, if somewhat puzzling, results two weeks ago.

Among nearly 8,900 participants who received two full doses of the vaccine, it had 62 percent efficacy. But after a discrepancy over methods for measuring the concentration of viral particles in the vaccine created uncertainty over the dosage during an early stage of manufacturing, 2,741 participants were given a half dose of the vaccine followed a month later by a full dose. In that smaller group of participants, the vaccine had 90 percent efficacy.

The Oxford scientists said in the paper, published in the Lancet, a British medical journal, that “further work is needed to determine the mechanism of the increased efficacy.”

Both dosing regimens appeared to protect participants in the trials from hospitalization or severe disease.

The results combined data from a trial in Brazil with a trial in Britain. In the British trial, the researchers asked participants to swab their noses and throats weekly to test for asymptomatic infections, a way of determining whether the vaccine could protect not only against disease but also transmission.

The vaccine appeared to be more effective in protecting against asymptomatic infections in the low-dose, high-dose regimen, but the numbers were so small that it was difficult to be sure. The researchers wrote in the paper that the results “provide some hope that Covid-19 vaccines might be able to interrupt some asymptomatic transmission,” though they said “more data are needed to confirm.”

Jenna Ellis, a senior legal adviser to President Trump, has tested positive for the coronavirus, according to a White House official familiar with the situation. She is the latest in a string of officials connected to Mr. Trump who have tested positive.

Ms. Ellis has appeared in recent weeks alongside Rudolph W. Giuliani and other Trump lawyers — a group Ms. Ellis has described as an “elite strike-force team” — at public hearings where she amplified the president’s false claims of widespread voter fraud.

Mr. Giuliani, the lead lawyer for the president’s efforts to overthrow the results of the election, confirmed over the weekend that he had tested positive for the virus, and a person who was aware of his condition but not authorized to speak publicly said then that he had been hospitalized at Georgetown University Medical. At age 76, Mr. Giuliani is in a high-risk category. Mr. Trump said on Monday that he had spoken to Mr. Giuliani and he was doing “very well.”

Ms. Ellis was photographed last week, on Wednesday, sitting next to Mr. Giuliani during a hearing before the Michigan House Oversight Committee. It was not immediately clear whether she had any symptoms, or what kind of test she had taken. Ms. Ellis continued to post to Twitter throughout the day on Tuesday, including sharing a statement attributed to her and Mr. Giuliani about their legal efforts. She did not respond to a message seeking comment.

Ms. Ellis has been a frequent guest on cable news, where she aggressively defended Mr. Trump as he faced investigation and impeachment. She presents herself as a constitutional law attorney, but has never appeared in federal district or circuit court, where most constitutional matters are considered, according to national databases of federal cases. She does not appear to have played a major role in any cases beyond criminal and civil work in Colorado.

Ms. Ellis’s most recent work appears to have been largely in a public-relations capacity. The Trump campaign and its supporters have so far filed about 50 election-related lawsuits. She has not signed her name or appeared in court to argue a single one.

At least 40 members of Mr. Trump’s administration, campaign and inner circle have contracted the virus since late September. In early October, Mr. Trump was hospitalized for a few days after testing positive and developing symptoms of Covid-19.

The complicated logistics at one vaccination center offer insights into the challenges ahead for a mass rollout of the new inoculation program across Britain. While the country has been getting ready for a vaccine for some time, only now are the difficulties involved in a program of this scale being fully understood.

Fiona Kinghorn, executive director of public health for the Cardiff and Vale University Health Board, who oversaw the vaccine rollout at one site in Cardiff, the capital of Wales, said setting up the center and delivering the first shots on Tuesday was a major undertaking.

“It’s not just this week, it’s been six months of work,” she said.

Work on a mass vaccination program began in earnest in June, long before it was clear which vaccine might be approved by the government and when. On Monday, the center received one batch of vaccine — a tray of vials containing 975 doses, five to each vial — that must be used within five days after being defrosted.

“We’ve had to prioritize and phase how we might bring people in,” she said. The center began with health care workers and social care staff.

Unlike flu vaccines, which come prepacked in syringes for easy use, the coronavirus vaccines must be prepared on site after they are defrosted, and then the prepared vials must be used within hours. The center was scheduled to provide 225 vaccinations on Tuesday and continue daily until they finish the tray. Any doses they failed to use in time would have to be discarded, creating a sense of urgency.

“We’re doing it with military precision, and in fact, we have had the military helping with our planning too,” Ms. Kinghorn said.

The center will receive its next tray of vaccine on Friday, and then will decide on the right time to defrost and begin using those.

Britain’s National Health Service began delivering shots of the Pfizer-BioNTech vaccine on Tuesday, opening a public health campaign with little precedent in modern medicine.

Here is a guide to some of the basics.

Britain’s drug regulator is seen as a bellwether agency, and its decisions often have influence abroad. In the case of the Pfizer vaccine, the agency has said that it did not cut any corners and undertook the same laborious process of vetting the quality, efficacy and manufacturing protocols of the vaccine.

Dr. Anthony S. Fauci, the United States’s top infectious disease expert, said last week that the British had not reviewed the vaccine “as carefully” as the United States was. But he walked back those comments the next day, saying: “I have a great deal of confidence in what the U.K. does both scientifically and from a regulator standpoint.”

Doctors and nurses, certain people 80 or over and nursing home workers.

Life will return to normal only when society as a whole gains enough protection against the coronavirus. Once countries authorize a vaccine, they’ll be able to vaccinate only a small percentage of their citizens in the first couple of months.

Once enough people get vaccinated, it will become very difficult for the virus to find vulnerable people to infect. Life may start approaching something like normal by the fall of 2021.

Yes, but not forever. The two vaccines that will potentially get authorized this month protect people from getting sick with Covid-19. But the clinical trials that delivered these results were not designed to determine whether vaccinated people could still spread the virus without developing symptoms.

The Pfizer and BioNTech vaccine is delivered as a shot in the arm, like other typical vaccines. The injection won’t be any different from ones you’ve gotten before. Tens of thousands of people have already received the vaccines, and none of them have reported any serious side effects. Some have felt aches and flulike symptoms that last less than a day.

There’s no evidence that it does, and there’s good reason to think that it does not.

Some claims have been floating around the web that coronavirus vaccines can harm a woman’s fertility. The supposed evidence rests on the fact that most coronavirus vaccines work by creating antibodies that attack the virus’s “spike” protein, and this protein has a minor resemblance to a protein crucial for the formation of the placenta.

But that does not mean that the antibodies generated by coronavirus vaccines would attack a pregnant woman’s placenta. The region of the placental protein that’s similar to spike is just too short to give the antibodies a grip.

The coronavirus vaccine made by Pfizer and BioNTech provides strong protection against Covid-19 within about 10 days of the first dose, according to documents published on Tuesday by the Food and Drug Administration before a meeting of its vaccine advisory group.

The finding is one of several significant new results featured in the briefing materials, which span 53 pages of data analyses from the agency. Last month, Pfizer and BioNTech announced that their two-dose vaccine had an efficacy rate of 95 percent after two doses administered three weeks apart. The new analyses show that the protection starts kicking in far earlier.

What’s more, the vaccine worked well regardless of a volunteer’s race, weight or age. While the trial did not find any serious adverse events caused by the vaccine, many participants did experience aches, fevers and other side effects.

On Thursday, the F.D.A.’s vaccine advisory panel will discuss these materials in advance of a vote on whether to recommend authorization of Pfizer and BioNTech’s vaccine.

Despite the early protection afforded by the first dose, it’s unclear how long that protection would last on its own, underscoring the importance of the second dose. Previous studies have found that the second dose of the Pfizer-BioNTech vaccine gives the immune system a major, long-term boost, an effect seen in many other vaccines.

Many experts have expressed concern that the coronavirus vaccines might protect some people better than others. But the results in the briefing materials indicate no such problem. The vaccine has a high efficacy rate in both men and women, as well as similar rates in white, Black and Latino people. It also worked well in obese people, who carry a greater risk of getting sick with Covid-19.

The Trump administration is requiring states to submit personal information of people vaccinated against Covid-19 — including names, birth dates, ethnicities and addresses — raising alarms among state officials who fear that a federal vaccine registry could be misused.

The Centers for Disease Control and Prevention is instructing states to sign so-called data use agreements that commit them for the first time to sharing personal information in existing registries with the federal government. Some states, such as New York, are pushing back, either refusing to sign or signing while refusing to share the information.

Gov. Andrew M. Cuomo of New York warned that the collection of personal data could dissuade undocumented people from participating in the vaccination program. He called it “another example of them trying to extort the State of New York to get information that they can use at the Department of Homeland Security and ICE that they’ll use to deport people.”

Administration officials say that the information will not be shared with other federal agencies and that it is needed for several reasons: to ensure that people who move across state lines receive their follow-up doses; to track adverse reactions and address safety issues; and to assess the effectiveness of the vaccine among different demographic groups.

At a briefing with a small group of reporters on Monday, officials from Operation Warp Speed, the government’s vaccine initiative, defended the plan. They said all but a handful of states had signed data agreements, and the rest would sign by the end of the week, though it is not clear how many states will submit personal information.

“There is no social security number being asked for, there is no driver’s license number,” said Deacon Maddox, who runs the operation’s data and analysis system. “The only number I would say that is asked is the date of birth.”

The hurried effort at data gathering, with delivery of vaccine doses expected to begin next week, is making many immunization experts deeply uneasy. At issue is the delicate balance between a patient’s right to privacy and the government’s right to invoke its expansive authority in the name of ending the deadliest pandemic in more than a century.

William Shakespeare Receives Coronavirus Vaccine in Britain

In Coventry, England, on Tuesday, a man named William Shakespeare, 81, joined Margaret Keenan, 90, as a recipient of the new coronavirus vaccine.

“I hear your having an an injection then, OK?” “OK.” “I’ll speak to you soon. Do you want me to look after these?” “Yes.” “OK.”

The world may be a stage, but William Shakespeare from Warwickshire didn’t flinch or shy away from his task: As Britain started to roll out the coronavirus vaccine on Tuesday, Mr. Shakespeare became the second person in the country to receive the vaccine outside a clinical trial

“It could make a difference to our lives from now on, couldn’t it?” Mr. Shakespeare, 81, said with a smile shortly after being vaccinated at University Hospital Coventry, in central England, just 20 miles north of where the man for whom he was named was born in 1564.

That one of the first recipients of the vaccine bore such a famous name — a fact that was confirmed by the National Health Service — brought surprise and lighthearted jokes, at a time when Britain faces the daunting task of mounting the largest vaccination campaign in its history.

“Shakespeare gets Covid vaccine,” the BBC wrote as a headline. Shakespeare’s comedy “The Taming of the Shrew” became The Taming of the Flu. And “The Two Gentlemen of Verona” quickly turned into The Gentlemen of Corona.

In a reference to Hamlet, one user wrote on Twitter, “If Margaret Keenan is patient 1A for the vaccine, would William Shakespeare be 2B, or not 2B … ,” about the first two patients to receive the vaccine.

Even Britain’s theaters weighed in.

Casting director: So what would you bring to the role of second patient? We want a sense of real drama and patriotism here.

Auditionee: I’m literally called William Shakespeare.

Casting director: Fair enough, the part’s yours. https://t.co/phnYvq0SSh

— Is it the National Theatre? Oh yes it is (@NationalTheatre) December 8, 2020

Mr. Shakespeare, who has been hospitalized in Coventry for several weeks after a stroke, received the shot in his left arm on Tuesday morning, wearing a hospital gown and bright red socks. He felt a little frail and took a nap in the afternoon, according to his niece, Emily Shakespeare.

“He’s delighted with it,” Ms. Shakespeare said in a telephone interview about her uncle’s first injection. “He’s dying to come home.”

Countless families around the world have been unable to visit relatives in nursing homes or hospitals during the pandemic, leaving many patients to suffer loneliness, atrophy and depression. Others died alone, and families never got to say goodbye.

So Mr. Shakespeare’s vaccination brought a bit of heartwarming news for people in Britain, and for his family. Within a few hours on Tuesday, he and Ms. Keenan had become the face of the country’s resilience against a virus that has killed more people in Britain than anywhere else in Europe.

“He is fed up being in the hospital,” Ms. Shakespeare said of her uncle, “but today I just want to say that I’m proud that he’s leading the way.”

She said it was “highly likely” that her uncle was related to “the” William Shakespeare, who died in 1616; she has traced his lineage back to the early 1700s, she said, but had more research still to do.

Britain’s health secretary, Matt Hancock, appeared to shed some tears on ITV as he heard the name of the first man in the country to receive the vaccine, which surely made Mr. Shakespeare raise an eyebrow, his niece said. “He’s left-leaning, so I’m not entirely sure how he feels about it,” Ms. Shakespeare added about the reaction from Mr. Hancock, a conservative.

May Parsons, the nurse who vaccinated Mr. Shakespeare and Ms. Keenan, said the injections were a first step in giving more people a sense of normality. “This is really important for me, knowing that they’re going to be safe, that they’re going to be protected,” Ms. Parsons told Sky News.

Unsurprisingly, Mr. Shakespeare’s name has brought him little moments of fame before, like the time in the 1960s when he was pulled over for speeding in Stratford-upon-Avon and the police officer did not believe it was his real name, Ms. Shakespeare said. “But this one goes beyond what he’s seen in the past,” she said.

It is also likely that another William Shakespeare will be vaccinated next year: Mr. Shakespeare’s 41-year-old son is also called William.

Ms. Shakespeare said the family wanted to remind everyone that there was much more at stake than the ephemeral fame of “their” William Shakespeare.

“He wants to to see his wife, his children and his grandchildren, who can’t visit him at the moment,” she said. “But the outpouring of attention will surely give him a boost.”

The Trump administration is said to have turned down an offer from Pfizer to purchase additional doses of its vaccine. Credit…Doug Mills/The New York Times

Before Pfizer’s coronavirus vaccine was proved highly successful in clinical trials last month, the company offered the Trump administration the chance to lock in supplies beyond the 100 million doses the pharmaceutical maker agreed to sell the government as part of a $1.95 billion deal months ago.

But the administration, according to people familiar with the talks, never made the deal, a choice that now raises questions about whether the United States allowed other countries to take its place in line.

As the administration scrambles to try to purchase more doses of the vaccine, President Trump plans on Tuesday to issue an executive order that proclaims that other nations will not get the U.S. supplies of its vaccine until Americans have been inoculated.

But the order appears to have no real teeth and does not expand the U.S. supply of doses, according to a description of the order on Monday by senior administration officials.

The vaccine being produced by Pfizer and its German partner, BioNTech, is a two-dose treatment, meaning that 100 million doses is enough to vaccinate only 50 million Americans. The vaccine is expected to receive authorization for emergency use in the U.S. as soon as this weekend, with another vaccine, developed by Moderna, also likely to be approved for emergency use soon.

Britain plans to begin a vaccination drive on Tuesday using the Pfizer-BioNTech vaccine, making it the first Western nation to start mass vaccinations.

On Nov. 11 — two days after Pfizer first announced early results indicating that its vaccine was more than 90 percent effective — the European Union announced that it had finalized a supply deal with Pfizer and BioNTech for 200 million doses, a deal they began negotiating in months earlier. Shipments could begin by the end of the year, and the contract includes an option for 100 million more doses.

Asked if the Trump administration had missed a crucial chance to snap up more doses for Americans, a spokeswoman for the Department of Health and Human Services said, “We are confident that we will have 100 million doses of Pfizer’s vaccine as agreed to in our contract, and beyond that, we have five other vaccine candidates.”

The government was in July given the option to request 100 million to 500 million additional doses. But despite repeated warnings from Pfizer officials that demand could vastly outstrip supply and amid urges to pre-order more doses, the Trump administration turned down the offer, according to several people familiar with the discussions.

In a statement, Pfizer said that “any additional doses beyond the 100 million are subject to a separate and mutually acceptable agreement,” and that “the company is not able to comment on any confidential discussions that may be taking place with the U.S. government.”

The bulk of the global supply of vaccines has already been claimed by wealthy countries like the United States, Canada, Britain and countries in Europe, leading to criticism that people in low- and middle-income countries will be left behind. The United States has declined to participate in a global initiative, called Covax, that is meant to make a vaccine available globally.

The decision to issue the executive order was reported earlier by Fox News.

Pope Francis canceled the traditional Dec. 8 papal visit to a Rome landmark because of social distancing concerns, he said on Tuesday. The afternoon event, observing the feast of the Immaculate Conception of the Virgin Mary, normally draws thousands of people.

“The traditional homage” did not take place, “to avoid the risk of crowds, as ordered by civil authorities, who we must obey,” Francis told the faithful who gathered in St. Peter’s Square for the Angelus prayer. Instead, the pope went to the site unannounced at 7 a.m., and left a bouquet of roses at the base of a column near the Spanish Steps that is topped by a statue of the Virgin Mary.

Other than in September and October, when new coronavirus cases in Italy appeared to have dropped significantly, Pope Francis has canceled most of his regular public appearances during the pandemic, so that crowds would not gather to see him. In their place, he has been streaming events online from the Apostolic Library in the Vatican. But he still appears every week at a window overlooking St. Peter’s Square to pray with and bless socially distanced worshipers below in the square.

Late last month, though, the pope did meet with a delegation of five N.B.A. players and officials from the players’ association privately at the Vatican to discuss their efforts to address social justice and economic inequality.

Health authorities said on Tuesday that people arriving in Hong Kong, who already must be tested on arrival and toward the end of the mandatory two-week quarantine, would also be required to be tested a third time three weeks after arrival. Hong Kong recorded 78 new cases on Monday, raising its total for the pandemic to 6,976 — tiny figures compared with most large Western countries, but a sign that even places that have been able to keep a tight lid on the virus are facing problems now.

  • Australia, where coronavirus cases are low, extended for another three months its ban on residents leaving the country, official said Tuesday. The country, which has some of the tightest restrictions anywhere, also extended its ban on cruise ships until March.

  • Chile announced new measures for Santiago, the capital, this week that are meant to avoid a total lockdown, the authorities said. The new restrictions include a full lockdown on weekends and lesser limitations during the week. The capital region reported an 18 percent increase in new cases last week, which “is shocking and worries us a lot,” said Enrique Paris, the health minister.

  • Four lions at the Barcelona Zoo have tested positive for the coronavirus, officials in Barcelona said Tuesday. The lions — three females and a male — were tested after showing symptoms, and were treated with anti-inflammatory drugs. Two employees also tested positive, officials said. It is the second known instance involving large felines: several lions and tigers at the Bronx Zoo in New York tested positive in April.

One of the biggest rites of college football — the annual Michigan-Ohio State game — is off for this weekend because of the coronavirus pandemic.

Michigan said Tuesday that it would be unable to play at fourth-ranked Ohio State on Saturday because of the number of virus cases inside its football program.

“The number of positive tests has continued to trend in an upward direction over the last seven days,” Warde Manuel, Michigan’s athletic director, said in a statement. “We have not been cleared to participate in practice at this time. Unfortunately, we will not be able to field a team due to Covid-19 positives and the associated quarantining required of close contact individuals.”

The cancellation raised the possibility that Ohio State (5-0) would prove ineligible for the Big Ten championship game on Dec. 19 because it had not played enough games this season. But conference officials have said that the Big Ten policy requiring teams to play at least six games to qualify for the title matchup could be adjusted.

Ohio State struggled with the virus toward the end of November and canceled its Nov. 28 game at Illinois. The Buckeyes had earlier missed out on a game when Maryland canceled because of its own virus troubles.

On Tuesday, a handful of people across Britain — mostly those 80 and over, health care workers and those working in nursing homes — began receiving the newly approved Pfizer vaccine. It was the first day that the inoculations were being administered in any Western nation.

Hilary Nelson, 45, an intensive care unit nurse in Scotland’s Forth Valley Royal Hospital who is also a nurse’s union representative, said it was important to get vaccinated as soon as possible.

“I want to get the vaccine to protect my colleagues, my family, but most of all the patients that we look after,” she said.

She hopes to serve as an example to others in the country, particularly those who may be doubtful of the vaccine’s safety, because she knows the heavy toll the disease has taken.

“I’ve sat with dying patients and had to call their loved ones on the phone,” she said.

“I’ve asked my questions, and I’m satisfied that it is safe.”

John Pollard, 90, was surprised to find out he was among the first patients in Britain to be offered the vaccine.

“Over the years, I’ve had all sorts of vaccinations,” he said. “I’ve never given it any thought really, all I thought was that I would like to not get Covid.” He lives on his own, so his daughter will be bringing him in for the vaccine at a hospital near his home in Brighton.

He plans to spend this Christmas at his daughter’s house, with his family around him and has high hopes for the new year: “If and when I feel if I feel fit enough, I might make a trip to Australia.”

Dr. Matt Morgan, 40, who works in the I.C.U. at University Hospital of Wales, Cardiff, has an appointment booked on Tuesday afternoon. He admitted the first Covid-19 patient to his hospital 38 weeks earlier to the day, and said things have come full circle. He was feeling “proud that science, humanity, the power of globalization, reason and truth” have produced a vaccine, ahead of his appointment Tuesday. “It’s been a very long year.”

His hospital is still dealing with new coronavirus patients on a regular basis, and he described the second wave of infections from this fall as more like a marathon than a sprint.

While he was hopeful about the new vaccine, he worried people may mistake the start of vaccination as the end of the pandemic.

“There’s still certainly going to be people who die between now and spring,” Dr. Morgan said. “There’s still going to be families who spend Christmas alone. So, you know, this won’t in one day make everything OK.”

At a newly created vaccine center on the outskirts of Cardiff, the capital of Wales, there was a small but steady flow of people coming in on Tuesday morning. Most were health care workers who entered the Cardiff and Vale Therapy Center — a former gymnasium used for rehabilitation therapy — wearing masks.

Betty Spear, a retired pediatric nurse, pulled back the blue curtain from the small cubicle she was working in after having administered the vaccine to a fellow nurse.

“She just cried and said this was such an emotional day,” Ms. Spear said of her most recent patient. “Generally, I think people are extremely happy that the day is coming, that the day has come that they are getting this vaccination.”

She added: “That last lady was very emotional, I think partly because she worked on a Covid ward, so she has seen the consequences and probably the outcomes. I presume she has seen a lot.”

Ms. Spear said she herself was “slightly anxious because it’s a different area but we’ve had a lot of training over the last few days.”

Nearly all of the people vaccinated here were health care workers, and many have experienced the virus’s horrors first hand. They expressed excitement and relief that there was some hope on the horizon for an end to pandemic.

Dr. Chris Hingston, 45, who is an I.C.U. consultant at the University Hospital of Wales, said he initially felt almost guilty for being among the first to receive the shot, pointing to the nurses in Covid wards as among the most in need. But after speaking with colleagues, he decided it was important to be inoculated as soon as possible to provide wider protection for his colleagues and patients.

“From my point of view, well, I’ve no fear of it. But you know, a lot of people out there, I think, are quite worried,” he said. “I don’t feel it’s for myself necessarily, having the vaccine. It’s really for others in many ways.”

When he received his vaccine on Tuesday morning, he likened it to having the flu shot.

“I didn’t even feel it,” he said as he chatted casually with Lynne Cronin, 60, the acting lead nurse at the center who delivered the vaccine.

“You’re exactly the people we need to come through,” she said, after learning that he is an I.C.U. doctor. Ms. Cronin said it had been a huge undertaking to get the site up and running for Tuesday, just days after the vaccine received emergency approval from the British government, but she lauded the local health authorities for their work.

“It’s been a huge ask to get everybody ready to vaccinate,” she said. “We’re still trying to train people up. We needed today and the next few days to sort any teething problems.”

She said other than a few early technical hiccups in the system being used to document the vaccinations, the roll out had been smooth.

“We just need to make sure it’s safe for people, and for my staff to make sure they are comfortable,” she said.

President-elect Joseph R. Biden Jr. appeared on Tuesday to formally name members of his health team, and vowed to change the course of the Covid-19 pandemic during his first 100 days in office.

The senior officials Mr. Biden will appoint — including Xavier Becerra, a former congressman who is now the California attorney general, as his nominee for secretary of health and human services — will face the immediate challenge of slowing the spread of the coronavirus, which has already killed more than 283,000 people in the United States and has taken a particularly devastating toll on people of color.

In making his announcement, Mr. Biden asked Americans to wear masks for the first 100 days of his presidency, and pledged to run “the most efficient mass vaccination plan in U.S. history” — including getting 100 million “vaccine shots into the arms of the American people” in his first 100 days. He also said he would set a “national priority” to get children back in school during that time period.

“My first 100 days won’t end the Covid-19 virus — I can’t promise that,” Mr. Biden said. But he added, “I’m absolutely convinced we can change course.”

Mr. Biden’s announcement, in Wilmington, Del., — where he appeared without wearing a boot on the ankle he twisted last month — started around the same time that a “virus summit” hosted by President Trump began at the White House.

In introducing Mr. Becerra, Mr. Biden stumbled a bit, mispronouncing the California attorney general’s last name. Mr. Becerra, 62, a Democrat who had carved out a profile more on the issues of criminal justice, immigration and tax policy, was long thought to be a candidate for attorney general, and he emerged as Mr. Biden’s clear choice for health and human services secretary only over the past few days, according to people familiar with the transition’s deliberations. It was a surprise ending to a politically delicate search that brought complaints from the Congressional Hispanic Caucus about a lack of Latinos in the incoming cabinet.

Other health officials included in the event today:

  • Dr. Rochelle Walensky, the chief of infectious diseases at Massachusetts General Hospital, to lead the Centers for Disease Control and Prevention, replacing Dr. Robert R. Redfield

  • Dr. Vivek Murthy as the surgeon general

  • Dr. Marcella Nunez-Smith to lead the Covid-19 equity task force

  • Jeff Zients as coordinator of the Covid-19 response.

  • Dr. Anthony S. Fauci, whom Mr. Biden has recruited to be his chief medical adviser in addition to continuing in his role as the director of the National Institute of Allergy and Infectious Diseases, is not expected to appear in-person at the event, but he is expected to make a video appearance.

The new Covid-19 vaccines from Pfizer and Moderna seem to be remarkably good at preventing serious illness. But it’s unclear how well they will curb the spread of the coronavirus.

That’s because the Pfizer and Moderna trials tracked only how many vaccinated people became sick with Covid-19. That leaves open the possibility that some vaccinated people could get infected without developing symptoms, and could then silently transmit the virus.

If vaccinated people are silent spreaders of the virus, they may keep it circulating in their communities.

“A lot of people are thinking that once they get vaccinated, they’re not going to have to wear masks anymore,” said Michal Tal, an immunologist at Stanford University. “It’s really going to be critical for them to know if they have to keep wearing masks, because they could still be contagious.”

In most respiratory infections, including the new coronavirus, the nose is the main port of entry. The virus rapidly multiplies there, jolting the immune system to produce a type of antibodies that are specific to mucosa, the moist tissue lining the nose, mouth, lungs and stomach. If the same person is exposed to the virus a second time, those antibodies, as well as immune cells that remember the virus, rapidly shut down the virus in the nose before it gets a chance to take hold elsewhere in the body.

The coronavirus vaccines, in contrast, are injected deep into the muscles and are quickly absorbed into the blood, where they stimulate the immune system to produce antibodies.

Some of those antibodies will circulate to the nasal mucosa and stand guard there, but it’s not clear how much of the antibody pool can be mobilized, or how quickly. If the answer is not much, then viruses could bloom in the nose — and be sneezed or breathed out to infect others.

This is why mucosal vaccines are better than intramuscular injections at fending off respiratory viruses, experts said.

The next generation of coronavirus vaccines may elicit immunity in the nose and the rest of the respiratory tract, where it’s most needed. Or people could get an intramuscular injection followed by a mucosal boost that produces protective antibodies in the nose and throat.

As some New York City school buildings reopen this week, Mayor Bill de Blasio has found himself presiding over a starkly unequal school system in which many white families have flocked back to classrooms while most families of color have chosen to learn from home indefinitely.

That gulf is illustrated in a startling statistic: There are nearly 12,000 more white children returning to public school buildings than Black students — even though there are many more Black students than white children in the system overall.

In New York and across the country, politicians and education officials have found that many nonwhite families are not ready to send their children back to classrooms, despite their struggles with remote learning, in part because of the disproportionately harsh impact the virus has had on their communities.

But the fact that so many students of color have chosen remote over in-person learning is raising alarms that existing disparities in the nation’s largest school system will widen, since remote learning has been far less effective.

New York’s issues with remote instruction begin with a lack of basic infrastructure for students learning from home. Many low-income students, including some living in homeless shelters, cannot even log on for classes because they do not have devices or Wi-Fi.

Educators also said they were scrambling to make lessons more engaging for students without much helpful guidance from the city. So while individual teachers and schools have honed creative strategies to improve online instruction, there is no citywide plan to do the same.

Latino students make up the largest share of students returning to classrooms, at about 43 percent, roughly proportional to their overall representation in the school system. But white children, who are less likely to be low-income than many of their peers, make up a quarter of students back in classrooms, even though they represent just 16 percent of overall enrollment.

Black and Asian-American families are significantly underrepresented in reopened classrooms. Just under 18 percent of Black families have chosen to send their children back to school, though those students make up nearly a quarter of the system. Asian-American children, who represent about 18 percent of the overall school system, make up the smallest share of children in classrooms this week, at just under 12 percent.

When Britons receive the Pfizer-BioNTech vaccine shots, they also get a wallet-size vaccination card showing that they have received the first of two required doses.

They are not ID cards; they do not contain any personal information, not even the person’s name. Even so, there are worries that they could be the beginning of a “passport” system that would divide society into two tiers, granting cardholders access to some services and businesses, like boarding a plane or eating at a restaurant, while others are excluded.

British health officials have argued that the cards are merely meant as a reminder of when a patient received the first shot and when they are scheduled to get the second, three weeks later.

The blue-and-white vaccination card, seen in images released by health officials, has spaces to record the vaccine name, dates of the injections and batch numbers. “Don’t forget your Covid-19 vaccination,” it reads. “Make sure you keep this record card in your purse or wallet.”

Britain faces tremendous logistical and security challenges to vaccinate millions of its citizens, and other countries will face them as well when they begin vaccination programs. The authorities have highlighted the need for a reliable record of who has been vaccinated, and have discussed the idea of issuing people documents certifying that they have received the vaccine or recovered from the disease, and thus presumably have some immunity.

But ministers in Prime Minister Boris Johnson’s government have brushed off the idea that the vaccination card will become a so-called immunity passport, and it remains unclear whether such a system will ever exist in Britain. Scientists are skeptical about the idea as well.

Two experts at the University of Birmingham noted in an article published on The Conversation that data on protected people following vaccination had not yet been published. “This is important because if we don’t understand the key ingredients for protection, we can’t monitor immunity effectively,” the experts — KK Cheng, a professor of public health and primary care, and Zania Stamataki, a lecturer in viral immunology, wrote on Monday.

They argued that while the vaccine greatly reduces the chance that the recipient will become severely ill, vaccinated people could still transmit infection to others, limiting an immunity passport’s usefulness.

“Being personally protected following successful vaccination does not absolve us of social responsibility,” they said.
