CDC modifications Covid vaccine steerage to OK mixing Pfizer and Moderna pictures

CDC changes Covid vaccine guidance to OK mixing Pfizer and Moderna shots

The Centers for Disease Control and Prevention have tacitly changed their guidelines for Covid-19 vaccine shots, stating that it is now okay to mix Pfizer and Moderna shots in “exceptional situations” and that it is in Okay, wait up to six weeks to get the second shot. Two-dose immunization from both companies.

While Pfizer and Moderna’s vaccines, both of which use messenger RNA technology, were approved 21 and 28 days apart, the agency now says that under new guidelines, you can get both shots as long as they’re at least apart 28 days administered will be published on its website Thursday.

Although “every effort” should be made to ensure that a patient receives the same vaccine, in rare situations “any available mRNA COVID-19 vaccine can be administered with a minimum of 28 days between doses” – if supply Is limited or the patient does not know what vaccine they originally received, the CDC says in new guidelines.

The CDC says the two products are not interchangeable, admitting that they hadn’t yet investigated whether their new recommendations would alter the safety or effectiveness of either vaccine.

The agency said health care providers should give patients a vaccination card detailing when they received their first shot and what type of shot it was to ensure patients know which shot to receive the second time. The agency also recommends providers to record the patient’s vaccination information on their medical records and on the government vaccination information system.

Both companies need two doses to achieve maximum protection against the coronavirus. While both shots should be administered according to the guidelines originally recommended, the CDC said the second dose of both companies’ vaccine could be delayed for up to six weeks if necessary.

The updated guidelines come as some cities and counties across the country cancel vaccination appointments because they don’t have as many doses as they originally expected.

Wayne County, Michigan, for example, said last week it would be a priority to make sure people who got their first shot get their second shot on time. But the county said it had to cancel nearly 1,400 appointments for people to get their first shot.

“The intent is not to suggest people do something else, but rather to give clinicians flexibility in exceptional circumstances,” said Jason McDonald, a CDC spokesman, in an email to CNBC.

Dr. Nancy Messonnier, director of the CDC’s National Center for Immunization and Respiratory Diseases, was asked on Friday about the interval at which the two shots should be administered.

“The data we have is of a two-dose vaccine on the recommended schedule of 21 or 28 days,” she said at a virtual event hosted by Harvard TH Chan School of Public Health and National Public Radio . “At this point in time, we at CDC agree with what the FDA says, and the FDA has made it very clear that we should be using the approved regimen.”

“It’s firmly ingrained in science and the evidence available, and doing anything else would not follow science and possibly not allow us to really get the full potential of these vaccines,” she added. “For now, from the CDC’s point of view, we think it has to be two doses on the recommended schedule.”

Submitting Go well with for ‘Wrongful Life’

Filing Suit for ‘Wrongful Life’

In an interview four years ago, Mr. Pope stated that at that point in time no one had received compensation for a “wronged life” lawsuit. Since then, several plaintiffs have received large payments, and the courts have weighed too.

In Georgia, Jacqueline Alicea won a $ 1 million settlement from the Doctors Hospital of Augusta and a surgeon there (from her insurers, to be precise). They had put their 91-year-old grandmother on a ventilator, ignoring both Ms. Alicea’s instructions as her grandmother’s health care representative and her grandmother’s prior instructions. That meant Ms. Alicea would eventually have to order the removal of the life support, a difficult decision.

Billing amounts often remain confidential, but “we wanted this bill to be called from the mountain tops,” said her attorney Harry Revell. “We wanted it to have a chilling effect on healthcare providers who don’t think it is important.”

The Alicea case, previously cited in other litigation, may have ramifications as the state appeals court and its Supreme Court, after the court denied a motion to dismiss, both ruled that the lawsuit can proceed. The parties reached an agreement on the eve of a trial in 2017.

In Montana, a jury announced what is believed to be the first verdict in an unjustified life case, awarding medical expenses of $ 209,000 and $ 200,000 in medical expenses to Rodney Knoepfle in 2019 for “mental and physical pain and suffering”.

Mr. Knoepfle was weakened by many illnesses and had a non-resuscitation order and a POLST form on his records at St. Peter’s Health, Helena’s largest hospital. “He’s been in more pain than anyone in his life and was happy with it when it was his time,” said Ben Snipes, one of his lawyers.

But a medical team resuscitated Mr. Knoepfle twice. He was tied to an oxygen tank and lived another two years before he died at the age of 69. “He’s been in almost no pain for the past few months, living in a hospital bed, and having morphine pressed into his pudding,” said Snipes.

Biden indicators order requiring vacationers put on masks on planes and at airports as pandemic rages

Biden signs order requiring travelers wear masks on planes and at airports as pandemic rages

President Joe Biden signed an ordinance on Thursday requiring masks to be worn on planes, trains, buses, and airports as coronavirus infections continue to rise.

The Trump administration declined to use masks for air travel and other transportation, leaving private companies to set their own guidelines, despite the Centers for Disease Control and Prevention having repeatedly recommended their use.

That left flight attendants and other staff to enforce the rules. Unions pushing for a federal mask mandate cheered Biden’s orders.

“What a difference leadership makes! We applaud President Biden’s nationwide approach to fighting the virus and getting out of this pandemic,” said Sara Nelson, president of the Association of Flight Attendants-CWA, the country’s largest flight attendants union. in a statement. “Today’s action by the executive regarding a mask mandate for interstate travel, including airports and airplanes, will provide much-needed support to flight attendants and aviation workers on the front lines.

Julie Hedrick, president of the Association of Professional Flight Attendants, which represents American Airlines cabin crews, also welcomed the move.

“As passengers travel on different airlines and through different airports, they deserve clear expectations of the rules. We thank President Biden for addressing this immediately,” she said in a statement.

All major US airlines require travelers to wear masks on board – a policy that extends to airports. Airline executives say the vast majority of customers follow the rule, but they vow to take a tough line against those who refuse. In the past week, airlines banned more than 2,500 people from flying for refusing to wear face covers. The FAA noted that some rare cases have even turned violent.

The FAA warned earlier this month to crack down on recalcitrant behavior and travelers who fail to follow instructions from the crew and fined those travelers up to $ 35,000.

Air travelers, including citizens, are recently required to show a negative Covid-19 test result before flying to the U.S. from overseas, Biden ordered, reiterating a CDC policy revealed last week. This rule takes effect on Tuesday.

Biden said travelers would have to self-quarantine upon arrival.

The Eggs I Offered, the Child I Gained

The Eggs I Sold, the Baby I Gained

I made it up to 33 weeks before Finnegan’s arrival. He was born folded and twisted like a street cart pretzel with knee, hip and elbow dislocations. He was born with lungs so weak that he needed the help of machines to breathe for almost two months. But he was born. And when I stared down at him in the intensive care unit and saw his resemblance to me – the blue eyes, the brown hair, the upturned nose that had called me Miss Piggy as a kid – I wondered, if Finnegan and I had one Been out together for a day and I’ve seen children who had the same set of characteristics. Or would my egg donor children, even if they had been mixed with an unknown Y chromosome, be unrecognizable even to me?

I recently listened to a podcast about the children of a serial sperm donor. Each of them innocently handed swabs to 23andMe, expecting to find out what part of the world they came from and what diseases they were prone to. Instead, they found that they had dozens of donor siblings (or “siblings” as they called each other). That annoyed me. I never thought there would be a line – traceable and findable for only $ 199 – from Finnegan to the children who may have been born from the eggs I sold. The cloak of anonymity under which I donated my eggs failed to predict the rapid rise in consumer DNA testing. Which meant that I couldn’t predict how the decision I made 10 years before Finnegan’s birth would resonate for the rest of his life.

When Finnegan, now 2, getting well at home – dropping his medication, growing out of his casts, and walking alone – I started pondering how Emmett and I would one day speak to him about his possible split siblings. After all these years, I had to wonder how I was looking at my egg donation.

Was it a means to an end, just a way to top up my skinny intern’s salary?

Was it the ultimate gift that made aspiring parents’ dreams possible?

Was that what I always suspect damaged my body and put Finnegan’s life at risk?

Or was it, as I imagined these revolving doors to be, the necessary precursor for everything in my life that I love? Not so much a revolving door as a sliding door, to borrow a Gwyneth Paltrow rom-com metaphor?

Yes. Yes. Yes. And yes.

And when we finally tell Finnegan his birth story, it will be a story of circumstances, close calls, a fateful cute meeting, and so much love. A story with at least one happy to the end. Or maybe up to 29.

I took ‘no pleasure’ in contradicting Trump on Covid

I took 'no pleasure' in contradicting Trump on Covid

White House Health Advisor Dr. Anthony Fauci said he had “had no pleasure” in contradicting former President Donald Trump on the Covid-19 pandemic and felt more liberated to be able to discuss science without facing the new administration.

“The idea that you can get up here and talk about what you know, what evidence, what the science is and what it is – let the science do the talking. It’s a liberating feeling,” Fauci said on Thursday at his first press conference in the White House for months.

Fauci, now advising President Joe Biden, said he took no pleasure in contradicting Trump, who often made false claims about the severity of the pandemic as well as drugs designed to fight it.

“It was very clear that there were things that were being said, be it about things like hydroxychloroquine and other things that were really [were] It’s uncomfortable because they’re not based on scientific facts, “said Fauci.” I can tell you, I take absolutely no pleasure in contradicting the president, so it really was something you didn’t think you could actually say something and it wouldn’t be affected. “

He said it was “a liberating feeling” to talk about science and “that’s it”.

During the pandemic, Trump repeatedly criticized the government’s top coronavirus advisor, and even suggested firing him. Meanwhile, Fauci has questioned a number of Trump’s comments, including his repeated claims that the US fight against the virus “is turning around” when tens of thousands of people were actually infected every day.

Fauci didn’t attack his former boss as subtly when asked how the pandemic might have developed differently if a team like Biden’s had been deployed from the start. “One of the things we’re going to do is be completely transparent, open and honest,” said Fauci. “When something goes wrong, don’t point your fingers, but correct it and make everything we do based on science and evidence.”

Fauci said he discussed these exact priorities with Biden about 15 minutes before entering the meeting room.

In contrast, Trump had consistently downplayed the threat posed by the virus. He regularly denied any criticism of his administration’s approach to the pandemic, claiming that the US, which has the highest Covid death toll of any country in the world, responded to the virus better than almost any other nation. While Fauci and Trump’s coronavirus task force held daily briefings at the start of the outbreak, those regular updates were eventually dropped after Trump asked scientists if they could inject disinfectant or light into the body to kill the virus.

Thursday’s press conference came after Fauci told the World Health Organization earlier in the day that the U.S. would remain a member of the international agency under Biden. In May, Trump announced that the US would leave the WHO, but the process shouldn’t be completed until July.

Fauci said the Biden administration plans to work with the other 193 member states to “strengthen and reform” the United Nations health agency.

Eli Lilly Claims Drug Prevents Coronavirus An infection in Nursing Houses

Eli Lilly Claims Drug Prevents Coronavirus Infection in Nursing Homes

An unusual experiment to prevent nursing home employees and residents from being infected with the coronavirus is successful, drug manufacturer Eli Lilly announced on Thursday.

A drug containing monoclonal antibodies – laboratory-bred virus fighters – prevented symptomatic infections in residents who have been exposed to the virus, even in the frail elderly, who are most vulnerable. This is based on preliminary results from a study conducted in collaboration with the National Institutes of Health.

The researchers found an 80 percent reduction in infections in residents who received the drug compared to those who received a placebo and a 60 percent reduction in staff, results that were very statistically meaningful, Eli Lilly said.

The data has not yet been reviewed or published by experts. The company expects to present the results at a future medical meeting and publish them in a peer-reviewed journal, but did not say when.

The study included 965 participants in nursing homes: 666 employees and 299 residents. (The company had hoped more residents would attend, but it proved difficult to enroll. Many had dementia and others were suspicious of intravenous medication.)

There were four deaths from Covid-19 among study participants. All of them were among those living in nursing homes who were given a placebo, not the drug.

The drug Bamlanivimab already has an emergency approval from the Food and Drug Administration, which enables Eli Lilly to make it available to symptomatic patients early in the course of their infection.

However, this study asked if the drug could stop infections before they started. It was an unusual experiment: medical staff rushed to nursing homes in trucks equipped with mobile laboratories as soon as a single infection was found there. Once the workers arrived, they set up temporary infusion centers to administer the drug.

The research ended that weekend with an emergency meeting of the Data Protection and Monitoring Committee, an independent group that oversees the incoming results. The data was strong and convincing enough to bring the placebos to a halt.

Covid19 vaccinations>

Answers to your vaccine questions

If I live in the US, when can I get the vaccine?

While the exact order of vaccine recipients may vary from state to state, most doctors and residents of long-term care facilities will come first. If you want to understand how this decision is made, this article will help.

When can I get back to normal life after vaccination?

Life will only get back to normal once society as a whole receives adequate protection against the coronavirus. Once countries have approved a vaccine, they can only vaccinate a few percent of their citizens in the first few months. The unvaccinated majority remain susceptible to infection. A growing number of coronavirus vaccines show robust protection against disease. However, it is also possible that people spread the virus without knowing they are infected because they have mild symptoms or no symptoms at all. Scientists don’t yet know whether the vaccines will also block the transmission of the coronavirus. Even vaccinated people have to wear masks for the time being, avoid the crowds indoors and so on. Once enough people are vaccinated, it becomes very difficult for the coronavirus to find people at risk to become infected. Depending on how quickly we as a society achieve this goal, life could approach a normal state in autumn 2021.

Do I still have to wear a mask after the vaccination?

Yeah, but not forever. The two vaccines that may be approved this month clearly protect people from contracting Covid-19. However, the clinical trials that produced these results were not designed to determine whether vaccinated people could still spread the coronavirus without developing symptoms. That remains a possibility. We know that people who are naturally infected with the coronavirus can spread it without experiencing a cough or other symptoms. Researchers will study this question intensively when the vaccines are introduced. In the meantime, self-vaccinated people need to think of themselves as potential spreaders.

Will it hurt What are the side effects?

The vaccine against Pfizer and BioNTech, like other typical vaccines, is delivered as a shot in the arm. The injection is no different from the ones you received before. Tens of thousands of people have already received the vaccines, and none of them have reported serious health problems. However, some of them have experienced short-lived symptoms, including pain and flu-like symptoms that usually last a day. It is possible that people will have to plan to take a day off or go to school after the second shot. While these experiences are not pleasant, they are a good sign: they are the result of your own immune system’s encounter with the vaccine and a strong response that ensures lasting immunity.

Will mRNA vaccines change my genes?

No. Moderna and Pfizer vaccines use a genetic molecule to boost the immune system. This molecule, known as mRNA, is eventually destroyed by the body. The mRNA is packaged in an oily bubble that can fuse with a cell, allowing the molecule to slide inside. The cell uses the mRNA to make proteins from the coronavirus that can stimulate the immune system. At any given point in time, each of our cells can contain hundreds of thousands of mRNA molecules that they produce to make their own proteins. As soon as these proteins are made, our cells use special enzymes to break down the mRNA. The mRNA molecules that our cells make can only survive a few minutes. The mRNA in vaccines is engineered to withstand the cell’s enzymes a little longer, so the cells can make extra viral proteins and trigger a stronger immune response. However, the mRNA can hold for a few days at most before it is destroyed.

“When I saw the results table, my jaw dropped,” said Dr. Myron Cohen, professor of medicine at the University of North Carolina at Chapel Hill and principal researcher who helped design and conduct the study.

Although the study has ended, Dr. Daniel Skovronsky, Eli Lilly’s chief scientist, said the company would continue to rush to nursing homes on its study network if an outbreak is detected. “Everyone will get the drug,” he said.

Experts who did not take part in the study were delighted, but emphasized that they had not yet seen complete data. “I only see positive results here,” said Dr. Ofer Levy, director of the Precision Vaccination Program at Boston Children’s Hospital. “That’s a win.”

Dr. Kathleen Neuzil, director of the Center for Vaccine Development and Global Health at the University of Maryland Medical School, was also encouraged.

“The mortality effect is remarkable,” she said, adding that the drug should be used more widely to prevent and treat Covid-19, “especially in populations such as nursing home residents who have high mortality rates and may not respond optimally to vaccines . ” ”

Vaccines also protect people from contracting the virus, of course, and nursing home staff and residents were among the first group to be prioritized for the shots. But supplies are inadequate, and many nursing home workers who fear the vaccines have refused to get them.

And after vaccination, it can take six weeks for the body to produce enough antibodies for maximum protection, said Dr. Srilatha Edupuganti, vaccine researcher at Emory University in Atlanta and study researcher.

Treatment with monoclonal antibodies could provide almost equivalent protection immediately, although it does not last as long as the protection offered by a vaccine.

Eli Lilly plans to reach out to the FDA for an emergency clearance to use the drug to help prevent infection in frail elderly populations, especially in nursing homes or long-term care facilities, said Dr. Skovronsky.

J&J plans to have 100 million vaccines for Individuals by spring, board member says

J&J plans to have 100 million vaccines for Americans by spring, board member says

Dr. Johnson & Johnson board member Mark McClellan told CNBC that “if the clinical trial works,” the company could significantly increase the availability of Covid vaccines in the coming weeks.

“I know J&J has a very large supply with its production both here in the US and elsewhere in the world, with the goal of maybe having enough vaccines for 100 million Americans by spring or April So,” said the former FDA commissioner in a Thursday evening interview on “The News with Shepard Smith”.

During a speech at the White House Thursday, government lead infectious disease doctor Anthony Fauci said Johnson & Johnson would have enough data on its vaccine to start analysis within a week or two. McClellan told host Shepard Smith that the most important thing about the company’s vaccine is the large-scale clinical trial that is ongoing.

“Based on these results, the independent scientists overseeing this study should take a closer look in the near future and we’ll see how quickly the vaccine could advance,” McClellan said.

According to the Centers for Disease Control and Prevention, an average of 883,000 syringes of the Covid vaccine are given per day in the US for the past six days. Even so, less than 50% of the 37,960,000 cans distributed have found their way into people’s arms.

At least 12 states have reported vaccine shortages. Officials from San Francisco and New York warned they could be completely out of dose this week. At least 15 vaccination sites in New York City are temporarily closed. New York Mayor Bill DeBlasio told NBC’s Gabe Gutierrez that at least 23,000 vaccine appointments must be postponed.

McClellan noted that “the supply will go up, but probably not enough to keep up with the large number of Americans who are now really looking to get vaccinated.” However, he told Smith that he believes the Biden administration can help speed up the vaccine adoption rate.

“It’s going to be a challenge, but I think more than 100 million Americans can be vaccinated in the next few months,” said McClellan, a health policy expert at Duke University.

President Joe Biden promised a “full war effort” to fight the coronavirus pandemic and accelerate vaccine production using the Defense Production Act during a briefing Thursday.

“We have already identified suppliers and are working with them to move the plan forward,” said Biden.

He added that the DPA would help fix supply chain issues, including a shortage of syringes.

Biden Inherits a Vaccine Provide Unlikely to Develop Earlier than April

Biden Inherits a Vaccine Supply Unlikely to Grow Before April

As the Biden administration takes power with a pledge to tame the most dire public health crisis in a century, one pillar of its strategy is to significantly increase the supply of Covid-19 vaccines.

But federal health officials and corporate executives agree that it will be impossible to increase the immediate supply of vaccines before April because of lack of manufacturing capacity. The administration should first focus, experts say, on fixing the hodgepodge of state and local vaccination centers that has proved incapable of managing even the current flow of vaccines.

President Biden’s goal of one million shots a day for the next 100 days, they say, is too low and will arguably leave tens of millions of doses unused. Data collected by the Centers for Disease Control and Prevention suggests that the nation has already reached that milestone pace. About 1.1 million people received shots last Friday, after an average of 911,000 people a day received them on the previous two days.

That was true even though C.D.C. data indicates that states and localities are administering as few as 46 percent of the doses that the federal government is shipping to them. An efficient vaccination regimen could deliver millions more shots.

“I love that he set a goal, but a million doses a day?” said Dr. Paul A. Offit, the director of the Vaccine Education Center at Children’s Hospital of Philadelphia and a member of a federal vaccine advisory board.

“I think we can do better,” he said. “We are going to have to if we really want to get on top of this virus by, say, summer.”

The pace of vaccination is critical not just to curbing disease and death but also to heading off the impact of more infectious forms of the virus. The C.D.C. has warned that one variant, which is thought to be 50 percent more contagious, might become the dominant source of infection in the United States by March. Although public health experts are optimistic that the existing vaccines will be effective against that variant, known as B.1.1.7, it may drive up the infection rate if enough people remain unvaccinated.

The current vaccination effort, which has little central direction, has sown confusion and frustration. Some localities are complaining they are running out of doses while others have unused vials sitting on shelves.

Mr. Biden is asking Congress for $20 billion to vastly expand vaccination centers to include stadiums, pharmacies, doctors’ offices and mobile clinics. He also wants to hire 100,000 health care workers and to use federal disaster relief funds to reimburse states and local governments for vaccination costs.

Dr. Mark B. McClellan, the director of Duke University’s health policy center, said those moves should help clear the bottlenecks and “push the number beyond a million doses a day and probably significantly beyond.”

The nation’s vaccine supply in the first three months of the year is expected to substantially exceed what is needed to meet the administration’s goal. According to a senior administration official, Pfizer-BioNTech and Moderna have been ramping up and are now on track to deliver up to 18 million doses a week. Together, they have pledged to deliver 200 million doses by the end of March. A third vaccine maker, Johnson & Johnson, might also come through with more doses. If all of that supply were used, the nation could average well over two million shots a day.

Asked Thursday afternoon by a reporter if one million shots a day was enough, Mr. Biden said: “When I announced it, you all said it’s not possible. Come on, give me a break, man. It’s a good start.”

Answers to Your Vaccine Questions

If I live in the U.S., when can I get the vaccine?

While the exact order of vaccine recipients may vary by state, most will likely put medical workers and residents of long-term care facilities first. If you want to understand how this decision is getting made, this article will help.

When can I return to normal life after being vaccinated?

Life will return to normal only when society as a whole gains enough protection against the coronavirus. Once countries authorize a vaccine, they’ll only be able to vaccinate a few percent of their citizens at most in the first couple months. The unvaccinated majority will still remain vulnerable to getting infected. A growing number of coronavirus vaccines are showing robust protection against becoming sick. But it’s also possible for people to spread the virus without even knowing they’re infected because they experience only mild symptoms or none at all. Scientists don’t yet know if the vaccines also block the transmission of the coronavirus. So for the time being, even vaccinated people will need to wear masks, avoid indoor crowds, and so on. Once enough people get vaccinated, it will become very difficult for the coronavirus to find vulnerable people to infect. Depending on how quickly we as a society achieve that goal, life might start approaching something like normal by the fall 2021.

If I’ve been vaccinated, do I still need to wear a mask?

Yes, but not forever. The two vaccines that will potentially get authorized this month clearly 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 coronavirus without developing symptoms. That remains a possibility. We know that people who are naturally infected by the coronavirus can spread it while they’re not experiencing any cough or other symptoms. Researchers will be intensely studying this question as the vaccines roll out. In the meantime, even vaccinated people will need to think of themselves as possible spreaders.

Will it hurt? What are the side effects?

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 health problems. But some of them have felt short-lived discomfort, including aches and flu-like symptoms that typically last a day. It’s possible that people may need to plan to take a day off work or school after the second shot. While these experiences aren’t pleasant, they are a good sign: they are the result of your own immune system encountering the vaccine and mounting a potent response that will provide long-lasting immunity.

Will mRNA vaccines change my genes?

No. The vaccines from Moderna and Pfizer use a genetic molecule to prime the immune system. That molecule, known as mRNA, is eventually destroyed by the body. The mRNA is packaged in an oily bubble that can fuse to a cell, allowing the molecule to slip in. The cell uses the mRNA to make proteins from the coronavirus, which can stimulate the immune system. At any moment, each of our cells may contain hundreds of thousands of mRNA molecules, which they produce in order to make proteins of their own. Once those proteins are made, our cells then shred the mRNA with special enzymes. The mRNA molecules our cells make can only survive a matter of minutes. The mRNA in vaccines is engineered to withstand the cell’s enzymes a bit longer, so that the cells can make extra virus proteins and prompt a stronger immune response. But the mRNA can only last for a few days at most before they are destroyed.

The administration is promising to purchase even more vaccine doses as they become available from the vaccine makers, and to use the Defense Production Act to spur production. But federal health officials and corporate executives said those were longer-term goals because the supply for the first three months of the year was essentially fixed.

The Trump administration invoked the Defense Production Act to force suppliers to prioritize orders from Pfizer, Moderna and other vaccine makers whose products are still in development. Health officials said it was unclear how the new administration could use the law beyond that to boost production.

One senior federal health official involved in the government’s vaccine efforts said that Operation Warp Speed, the Trump administration’s crash development program, had looked at all available manufacturing capacity domestically and globally and that there was little space left to negotiate at this point. The official said that if there had been more doses available to the government in the first quarter, they would have been purchased.

Experts generally agree that the federal government should be locking in purchases of as many doses as possible because no one knows yet how long the vaccines will protect against the coronavirus, whether booster shots will be required and what threats mutations of the virus could pose.

From April and thereafter, the supply outlook brightens. Pfizer and Moderna have each committed to supply another 100 million doses by the end of July, and the companies might be able to provide even more. A week ago, Pfizer and BioNTech, its German partner, increased their global production target to 2 billion doses for the year from 1.3 billion doses.

Pfizer has delayed deliveries to European countries while it retools its Belgium factory to expand production. But at the firm’s factory in Kalamazoo, Mich., which supplies doses for Americans, production has quickened since the federal government ordered suppliers to prioritize Pfizer’s needs. The unexpected discovery that efficient syringes could extract a sixth dose from its vials also upped Pfizer’s estimates.

Moderna has also raised its production targets for the year to 600 million doses, up from 500 million.

Johnson & Johnson is expected to announce results from its vaccine trial within days. If that vaccine proves effective, it could drastically speed up the pace of vaccinations because unlike Moderna’s and Pfizer-BioNTech’s vaccines, it requires only one dose. The company could apply for emergency use authorization from the Food and Drug Administration as soon as the end of the month. While its manufacturing has lagged, Johnson & Johnson is trying to catch up to the goals detailed in the federal contract it signed last year.

The firm is now expected to deliver anywhere from several million to 12 million doses by the end of February, and 10 million to 20 million more doses at the end of March or the first week in April, according to several people familiar with the firm’s manufacturing output. The first batch would be produced at its Dutch factory, and later batches at a factory in Baltimore operated by its manufacturing partner, Emergent BioSolutions.

But to deliver the second batch that quickly, federal regulators may have to agree to delay certain manufacturing reviews of the vaccine from the Baltimore plant, according to people familiar with the situation. Those discussions are now underway.

Johnson & Johnson is also in preliminary talks with Merck, a major American pharmaceutical company, about using its production lines, one of several ideas that federal health officials discussed with the Biden transition team. Federal officials are interested in boosting the nation’s vaccine-making power long-term, and Merck’s facilities may be among the few with remaining manufacturing capability.

But Dr. McClellan, who sits on Johnson & Johnson’s board of directors, said it would take months to adapt Merck’s factory to produce Johnson & Johnson’s vaccine. A senior administration official predicted that it could take until the end of the year.

Other vaccine makers may also come through by midyear. Novavax has worked to iron out what were recently dire manufacturing problems that delayed its clinical trials. Moncef Slaoui, the scientific head of the federal vaccine development program in the Trump administration, said in a recent interview that Novavax could apply for emergency use authorization in late April. The government has already ordered 110 million doses of the Novavax vaccine, to be delivered by the end of June, and Novavax has said it believes it can meet that target.

Mr. Biden has surrounded himself with new health officials assigned to getting vaccines from factories to recipients, including Dr. Bechara Choucair, the former Chicago health commissioner who is the White House’s vaccinations coordinator, and Tim Manning, a former top official at the Federal Emergency Management Agency who is now the supply coordinator. Dr. David Kessler, the former F.D.A. commissioner, will help lead the federal government’s vaccine development program at the Department of Health and Human Services, with special attention to manufacturing.

After both the Pfizer-BioNTech and Moderna vaccines proved to be highly effective in clinical trials late last year, the Trump administration considered whether to rethink its strategy of backing six different vaccine makers and instead throw all of its weight behind the proven producers. One senior administration official described “countless hours of debate” over the issue.

In the end, officials decided it was critical to keep aiming for a broad portfolio of vaccines, in part because no one has figured out which vaccines might work best for children or be most effective against emerging variants. They recommended that the Biden administration do the same.

Heute vor genau einem Jahr bestätigten die Zentren für die Kontrolle und Prävention von Krankheiten den ersten Fall eines neuen Coronavirus auf US-amerikanischem Boden, den Wissenschaftler damals 2019-nCoV anriefen.

Seitdem hat das Land nach Angaben der Johns Hopkins University mehr als 24 Millionen Fälle und mehr als 400.000 Todesfälle verzeichnet. Ein neuer Präsident tritt sein Amt an und warnt davor, dass sich die Pandemie verschlimmern wird, bevor sie sich bessert.

Experten für öffentliche Gesundheit, Ärzte, Wissenschaftler und Führungskräfte aus Industrie und Regierung sagen jedoch, dass uns das vergangene Jahr viel über das Virus beigebracht hat – und wie diese Lehren angewendet werden können, um die Pandemie jetzt zu verlangsamen.

Ihre Erkenntnisse reichten von Erkenntnissen über das Virus selbst und dessen Ausbreitung – erinnern Sie sich, als wir alle unsere Lebensmittel mit Clorox abwischten? – Überlegungen zu unserem eigenen Verhalten und wie es uns zu immer höheren Infektionsraten verurteilt.

Einige, von dem ehemaligen Mitglied des Nationalen Sicherheitsrates, Dr. Luciana Borio, und dem Chef der Operation Warp Speed, Moncef Slaoui, betonen, wie wichtig es ist, frühzeitig mit der Industrie zusammenzuarbeiten. Andere sagen, das vergangene Jahr beweise, dass das Versprechen unserer biomedizinischen Technologien schnell verwirklicht werden kann – wenn sie nur gut genug finanziert sind.

Hier sind ihre Gedanken.

Auf den Virus

“Es ist nicht das Winter-Atemwegsvirus, für das es in Rechnung gestellt wurde”, sagte Dr. Paul Offit vom Kinderkrankenhaus in Philadelphia. “Es ist weitaus weitreichender und schädlicher als das.”

Vorhersagen im Frühjahr über den Verlauf des Virus warnten davor, dass es den Mustern der Influenzapandemie von 1918 ähneln könnte: eine mildere erste Welle, gefolgt von einer viel tödlicheren zweiten im Herbst.

Der Herbst 2020 brachte letztendlich eine befürchtete größere Welle von Coronavirus-Fällen mit sich, aber es war nicht wie ursprünglich erwartet nach einem einheitlichen Tiefpunkt durch den Sommer. Mitte Juli erreichte ein Höhepunkt mit etwa 76.000 Fällen, als das Virus über Florida, Texas und Arizona verbreitet wurde.

Zu diesem Zeitpunkt hatten Wissenschaftler bereits einen Überblick darüber, was dieses Virus so schädlich macht, sagten Experten, da sich die Erkenntnisse in den ersten Monaten rasant entwickelten.

“Anfang Januar letzten Jahres wurde uns mitgeteilt, dass es keine Übertragung von Mensch zu Mensch gibt”, sagte Dr. Megan Ranney von der Brown University. “Als wir merkten, dass es sich ausbreitete [person-to-person]Wir dachten, es würde sich wie eine Grippe ausbreiten … wir dachten, wir müssten uns Sorgen um Tröpfchen und Fomiten machen. “

Das hat sich geändert, sagte Ranney, “als wir diese erste schreckliche nordöstliche Welle überstanden haben.”

Die Tatsache, dass die Übertragung “mehr in der Luft ist als ursprünglich angenommen, weniger oberflächlich als ursprünglich angenommen”, hat wichtige “Auswirkungen auf Präventionsempfehlungen”, sagte Dr. Carlos del Rio von der Emory University. Daher: Masken und Vermeidung großer Versammlungen in Innenräumen.

Wissenschaftler haben aber auch gelernt, dass dieses Virus schwieriger ist als andere. Die Tatsache, dass es einige tödlich trifft, während andere stillschweigend infiziert werden, macht es tatsächlich so gefährlich, sagte Dr. Jeremy Faust vom Brigham and Women’s Hospital in Boston.

“Asymptomatische Übertragung hat einerseits gute Nachrichten: Nicht jeder wird so krank, wie wir dachten”, sagte Faust. “Andererseits ist es so viel schwieriger zu kontrollieren, weil die Leute denken: ‘Wenn es mir gut geht, geht es mir gut. Ich darf keine Gefahr für mich selbst oder andere sein.'”

Dr. Leana Wen, ehemalige Gesundheitskommissarin von Baltimore, sagte, dass die Denkweise den größten Teil der Verbreitung ausmacht, wenn wir durchschnittlich fast 200.000 Fälle pro Tag aufzeichnen.

“Es gibt immer noch ein gewisses Maß an magischem Denken, wenn es um Menschen geht, die wir kennen und lieben und die nicht in unserem Haushalt sind”, sagte sie. “Wir denken, ‘Nun, diese Person sieht gut aus; ich kenne sie, ich vertraue ihnen, dass sie sich nicht auf risikoreiche Verhaltensweisen einlassen würden, also werde ich sie sehen.'”

Da Menschen ohne Symptome so viel Ausbreitung verursachen können – laut CDC mehr als die Hälfte -, ist es am besten, “jeden so zu betrachten, als ob er ein Coronavirus haben könnte”, sagte Wen.

Über menschliches Verhalten

“Wir haben das Gefühl einer sich verändernden Grundlinie entwickelt”, sagte Dr. Michael Osterholm von der University of Minnesota. Im April, sagte er, fühlte es sich an, als ob das “Haus in Flammen stand”, wobei jeden Tag 32.000 Fälle gemeldet wurden. Bis Mai waren es nur noch etwa 20.000. “Die Leute hatten das Gefühl, wir hätten die Kurve abgeflacht, wir waren fertig”, sagte er.

Bis Mitte Juli erreichte dieser Anstieg durch den Sonnengürtel einen bisher unergründlichen neuen Höchststand von mehr als 70.000 Fällen pro Tag. Anfang September fielen die Fälle auf 26.000 zurück, eine Zahl, die “fast so hoch war wie das Hoch im April, aber die Leute meinten:” Sehen Sie, das ist gut, es ist unter Kontrolle “, sagte Osterholm.

Im Oktober begann der obere Mittlere Westen mit einer Infektion zu leuchten, und “zu Thanksgiving hatten wir fast 200.000 Fälle pro Tag”, sagte er. Auf dem jüngsten Höhepunkt des Landes, dem 8. Januar, wurden an einem einzigen Tag mehr als 300.000 Fälle gemeldet.

“Denken Sie an 300.000 gegenüber 32.000”, sagte Osterholm. “In einem Zeitraum von April bis Januar wurden wir taub dafür. Jeder von ihnen ist eine sich verändernde Grundlinie, und plötzlich scheint das, was geschah, nicht mehr so ​​schlimm zu sein.”

Es sei Teil der menschlichen Verfassung, auf diese Weise zu reagieren, um “ein Gefühl des Überlebens zu entwickeln”. Aber es ist eine zentrale Herausforderung, das Blatt in der Pandemie zu wenden.

Auch, so Osterholm und Ranney, befassen sich mit den strukturellen Problemen, die die Hauptlast der Pandemie auf die Armen, Verletzlichen und Farbigen ausüben.

“Wenn wir Strategien für die öffentliche Gesundheit entwickeln oder umsetzen, um eine Epidemie zu bekämpfen, sei es struktureller Rassismus, wirtschaftliche Ungleichheit, Trennung zwischen Ländern mit hohem und niedrigem Einkommen, wenn wir nicht auf die Treiber des Verhaltens der Menschen achten, werden wir scheitern.” Sagte Ranney. “Auch mit guter Wissenschaft.”

Borio, der zusammen mit Osterholm als Covid-19-Berater für den Biden-Übergang fungierte, bezeichnete die Bedeutung der Führung als das wichtigste Lernen aus dem vergangenen Jahr.

“Es muss oben beginnen”, sagte sie. “Eine geteilte Nation kann eine Pandemie nicht bekämpfen. Unsere Regierung, riesig und komplex, verfügt über enorme Fähigkeiten, organisiert sich aber nicht selbst.”

Aber halten Sie die Politik so weit wie möglich davon ab, fügte Slaoui hinzu, der letzte Woche als Chefberater der Operation Warp Speed ​​zurückgetreten war, der Trump-Administration, die sich bemühte, Impfstoffe und Medikamente für Covid-19 zu entwickeln.

“Wir dürfen Fragen der öffentlichen Gesundheit nie wieder politisieren”, sagte Slaoui. “Ich bin sicher, das hat Zehntausende Menschenleben gekostet.”

Über Regierung und Industrie

Sowohl Slaoui als auch Borio sowie der frühere FDA-Kommissar Dr. Scott Gottlieb, der auch CNBC-Mitarbeiter und Vorstandsmitglied von Pfizer und Illumina ist, sagten, das erste Jahr der Pandemie habe gezeigt, wie wichtig öffentlich-private Partnerschaften sind und wie man auf sie einwirkt schnell.

“Die Weigerung von CDC, frühzeitig zu kommerziellen Labors und kommerziellen Testkits zu wechseln, hat uns für die frühe Verbreitung blind gemacht”, sagte Gottlieb.

Die Fähigkeit der USA, das Virus zu erkennen, wurde in den ersten Wochen durch einen Test der CDC beeinträchtigt, der sich als fehlerhaft herausstellte.

“Das Virus konnte tief in unseren Gemeinden verwurzelt werden”, fügte er hinzu. “Es war ein historischer Misserfolg.”

Borio wies auf die Bedeutung von Datensystemen hin, die von Palantir erstellt wurden, Gensequenzierungspartnerschaften mit Unternehmen wie Illumina, diagnostische Tests durch Quest und LabCorp sowie die Verteilung von Impfstoffen über CVS und Walgreens.

“Ein wirklich modernes öffentliches Gesundheitssystem erfordert eine öffentlich-private Partnerschaft”, sagte sie.

Borio betonte jedoch auch die Bedeutung der Strenge im Regulierungsprozess und die Gefahren einer “vorzeitigen Erteilung” der Genehmigung für den Notfall, “bevor Daten aus angemessenen und gut kontrollierten Studien vorliegen, wie sie für viele der Therapeutika aufgetreten sind”.

Insbesondere Hydroxychloroquin war ein blaues Auge für die Food and Drug Administration, die im Juni ihre Genehmigung zur Verwendung in Notfällen für Covid-19 widerrief, nachdem festgestellt wurde, dass es wahrscheinlich nicht wirksam ist.

Das, sagte Borio, “hilft den Patienten nicht.”

Slaoui, der die wissenschaftliche Entwicklung bei einer der größten öffentlich-privaten Partnerschaften in der Krankengeschichte durch Operation Warp Speed ​​beaufsichtigte, betonte auch die Notwendigkeit, bessere klinische Studien durchführen zu können. Er sagte an einigen Stellen im letzten Jahr, dass in den USA mehr als 400 Studien durchgeführt wurden, die meisten ohne Placebo-Kontrolle, was als Goldstandard für das Testen neuer Therapien gilt. Viele nahmen auch nur eine Handvoll Patienten auf.

“Das ist äußerst ineffizient und mit hohen Opportunitätskosten verbunden”, sagte Slaoui.

Auf Technologie

Was gut kontrollierte Studien jedoch bewiesen haben, war, dass “mRNA-Impfstoffe funktionieren”, sagte Ranney. “Die Tatsache, dass wir nicht nur einen, sondern zwei mRNA-Impfstoffe haben, die effektiv beim Menschen eingesetzt wurden und sowohl sicher als auch wirksam bei der Vorbeugung der Krankheit sind, ist einfach riesig.”

Laut Borio wären sie jedoch nicht möglich gewesen, “ohne frühzeitige Investitionen der US-Regierung vor vielen Jahren; die Entwicklung dieser Technologien dauert Jahre.”

Sie nannte sie die “aufregendste Innovation in der Impfstofftechnologie seit Jahrzehnten”.

Der Ausbruch bewies auch die Geschwindigkeit und Nützlichkeit einer zweiten Technologie, Impfstoffe, die harmlose Viren verwenden, um genetisches Material vom Coronavirus zu den Körperzellen zu befördern, um eine Immunantwort auszulösen, sagte Slaoui. “Es gibt mindestens zwei sehr schnelle Impfstoffplattformen, mit denen Impfstoffe in Monaten entwickelt werden können”, fügte er hinzu.

“Was wir vermisst haben”, sagte er, “sind Produktionskapazitäten und -fähigkeiten.”

Slaoui sagte, die Antwort sei etwas, das er als Biopräparationsorganisation bezeichnet habe, die neue Impfstoffe gegen neu auftretende Bedrohungen entwickeln und sofort Hilfe leisten könne, wenn diese Bedrohungen eintreten würden. Er brachte die Idee zum ersten Mal im Jahr 2016 auf, als er Vorsitzender der Impfstoffe bei GlaxoSmithKline war, und sagte, sie habe sich nicht durchgesetzt, “aber wir müssen sie jetzt wiederbeleben.”

Borio zitierte die Ernennung von Eric Lander zum besten Wissenschaftsberater von Biden in einer neu erhöhten Position auf Kabinettsebene als Signal für eine neue Ära, in der die Wissenschaft “ein wesentlicher Bestandteil des politischen Entscheidungsprozesses sein wird”.

Offit, ein Experte für Impfwissenschaft, drückte es ganz klar aus: “Wir haben es in uns, einen Impfstoff sehr schnell herzustellen und zu testen”, sagte er, “wenn wir bereit sind, das Geld auszugeben.”

Vorausschauen

Trotz der Lehren aus dem ersten Jahr der Covid-19-Pandemie warnten Experten des öffentlichen Gesundheitswesens vor einem schwierigen Weg nach vorne.

“Was mir am meisten auffällt, ist, wie viel wir noch nicht wissen”, sagte Dr. Kayvon Modjarrad, Direktor der Abteilung für neu auftretende Infektionskrankheiten am Walter Reed Army Institute of Research.

Fragen wie: Wie verhält sich dieses Virus anders als andere Atemwegsviren? Wie entwickelt es sich? Warum verursacht es bei einigen so schwere Krankheiten, bei anderen jedoch asymptomatisch?

“In der Wissenschaft besteht der erste große Schritt zur Lösung eines der Rätsel der Natur darin, zu verstehen, wie groß das Rätsel ist und welche Fragen zu stellen sind”, sagte Modjarrad. “Wir erreichen diesen Punkt erst jetzt.”

Eine der dringendsten Herausforderungen besteht darin, dass eine als B.1.1.7 bekannte Variante, die als übertragbarer angesehen wird als frühere Formen des Coronavirus, wahrscheinlich “in den nächsten Wochen bis Monaten abheben wird”, sagte Osterholm. Das heißt: “Wir konnten die schlimmsten Tage der Pandemie vor uns sehen, selbst mit dem Impfstoff.”

Zu den dringendsten Aufgaben der Biden-Regierung gehört die Verwaltung der Verteilung von Coronavirus-Impfstoffen, für die ein Ziel von 100 Millionen Dosen festgelegt wurde, die in den ersten 100 Tagen verabreicht wurden.

Osterholm stellte jedoch fest, dass in diesem Tempo – selbst wenn ein zusätzlicher Impfstoff für die Verwendung freigegeben wird, für den nur eine Dosis erforderlich ist, wie Johnson & Johnson’s in den nächsten Monaten erwartet wird – nur etwa 14% der US-Bevölkerung vollständig von geimpft würden Ende April.

Zusammen mit geschätzten 30% der Bevölkerung, die bereits infiziert sind und möglicherweise Immunität haben, ist dies weniger als die Hälfte des Landes, das bis in den Mai hinein geschützt ist, “weit entfernt von jeglicher Herdenimmunität”, sagte Osterholm.

“Impfstoffe spielen keine Rolle, nur Impfungen”, fügte Modjarrad hinzu, Direktor der Abteilung für neu auftretende Infektionskrankheiten am Walter Reed Army Institute of Research. “Wir können uns nicht zu viel gratulieren oder zu früh den Sieg erklären.”

Dr. Anthony Fauci, der landesweit führende Wissenschaftler für Infektionskrankheiten, sagte diese Woche, er erwarte, dass das Land 75 bis 80% seiner durch den Herbst geimpften Bevölkerung erreichen könne.

“Wenn wir das von April, Mai, Juni, Juli, August an effizient tun”, sagte er den Gastgebern eines Livestreams von Harvard Business Review, “sollten wir bis zum Beginn des Herbstes das Maß an Schutz haben, das wir haben.” Ich denke, wir können zu einer Form der Normalität zurückkehren. “

Hypertension Throughout Being pregnant Tied to Later Cognitive Decline

Excess Weight During Pregnancy Tied to Fertility Issues in Sons

Women who develop gestational hypertension – high blood pressure during pregnancy – may have decreased cognitive abilities later in life, according to a recent report.

The study in neurology included 115 women with a history of gestational hypertension between 2002 and 2006. They measured their mental agility an average of 15 years later using well-validated tests of verbal language proficiency, processing speed, memory and visual skills. They then compared their results with those of 481 women whose blood pressure remained normal during their pregnancy.

After checking ethnicity, educational level, pre-pregnancy BMI, and other factors, they found that women who were hypertensive during pregnancy had significantly lower scores on working memory and verbal learning tests than women whose blood pressure was normal .

The lead author, Dr. Maria C. Adank, a researcher at Erasmus University in Rotterdam, pointed out that the effect was mainly driven by 70 percent of the women in the study who had only mild hypertension – scores above 140/90 – and not the 30 percent who had preeclampsia, the extremely high blood pressure that, if left untreated, can lead to organ damage and death in both mothers and babies.

“These are women with only mildly high blood pressure. You are healthy. But even by the age of 45, they were affecting your cognition, ”she said. “You and your doctors should be aware of the risk and should be followed up. We believe that high blood pressure persists beyond pregnancy and should be treated. “
