Rice College Says Virus Take a look at Glitch Prompted False Positives

Rice University, where more than 95 percent of students are vaccinated, announced a move to remote classes last week after testing showed an alarmingly high number of community members with breakthrough coronavirus infections.

Those results, the university now says, were badly distorted by a testing glitch.

Of 4,500 tests administered on the Rice campus, 81 had returned positive results, mostly in vaccinated members of Rice’s community. Even in Houston, where the Delta variant was surging, the results were a surprise. Rice had taken tough efforts to control coronavirus in its community, practically demanding that students, faculty and staff be vaccinated, even as the state of Texas prohibited vaccination mandates. The university also required masks.

Further examination revealed that most of the people who appeared to have tested positive were actually negative for the virus, the university now says.

When Rice began to examine the cases, it found that the results didn’t make sense, according to a note to the university community on Sunday from Kevin E. Kirby, vice president for administration at Rice. Most of the people who tested positive did not have any symptoms. And the cases were scattered, with no clusters.

Rice discovered that the testing provider that reported so many positive results had just switched to using a new test. When 50 of the people who tested positive were retested using different types of tests, all but one of the results came back negative.

All the same, Rice says that it plans to stick with its decision to move to remote learning until Sept. 3. According to a university Covid dashboard, Rice now considers only 27 of the 4,500 tests administered on campus since Aug. 13 to have yielded true positive results, not 81.

Quidel recollects Lyra Covid take a look at attributable to excessive threat of false detrimental outcomes

A man inquires in a mobile test car in Brooklyn, New York, the United States, Jan.

Brendan McDermid | Reuters

Quidel is recalling its Lyra Covid-19 assay test due to a high risk of false negative results in patients who actually have high levels of the virus.

Quidel is a company that makes diagnostic health products worldwide. The Covid test received emergency approval from the Food and Drug Administration in March. It uses a swab sample from the nasal area to detect RNA that is specific for the SARS-CoV-2 virus.

“False-negative results can lead to delayed diagnosis or inadequate treatment of SARS-CoV-2, which can harm the patient, cause serious illness and death,” the FDA wrote on its website announcing the recall.

False negative results could also spread the virus further into a community, putting others at high risk of injury or death.

Quidel has received five complaints about the product, but there are currently no reports of injury or death from its use. The company’s stock plunged around 5% in after-hours trading.

For China’s Single Moms, a Highway to Recognition Paved With False Begins

For a few wonderful weeks, Zou Xiaoqi, a single mother in Shanghai, felt accepted by her government.

After giving birth in 2017, Ms. Zou, a financial clerk, went to court to question Shanghai’s policy of granting maternity benefits only to married women. She had little success and lost one lawsuit and two appeals. Then, earlier this year, the city suddenly dropped its marriage obligation. In March, a jubilant Ms. Zou received a performance check on her bank account.

She had barely started partying when the government reintroduced policy a few weeks later. Unmarried women were again not entitled to government payments for medical care and paid vacation.

“I always knew there was this possibility,” said Ms. Zou, 45 years old. “If you can get me to return the money, I will probably return it.”

The Shanghai authorities’ flip-flop reflects a broader view in China of longstanding attitudes towards family and gender.

Chinese law does not specifically prohibit single women from giving birth. However, official family planning guidelines only mention married couples, and local officials have long provided benefits based on these provisions. Only Guangdong Province, which borders Hong Kong, allows unmarried women to apply for maternity insurance. In many places women still face fines or other punishments for childbirth out of wedlock.

But as China’s birthrate has plummeted in recent years and a new generation of women embraced feminist ideals, these traditional values ​​have come under increasing pressure. Now a small but determined group of women are demanding guaranteed maternity benefits regardless of marital status – and, more generally, recognition of their right to make their own reproductive choices.

The U-turn in Shanghai, however, highlights the challenges facing feminists in China, where women face deeply ingrained discrimination and a government that is suspicious of activism.

It also shows the authorities’ reluctance to give up decades of control over family planning, even in the face of demographic pressures. The ruling Communist Party announced Monday that it would end its two-child policy, which allows couples to have three children in the hope of reversing a falling birth rate. However, single mothers remain unrecognized.

“There has never been a change in the policy,” said a Shanghai maternity hotline agent when he was reached by phone. “Single mothers never met the requirements.”

Ms. Zou, who found out she was pregnant after breaking up with her boyfriend, said she would continue to fight for recognition even though she didn’t need the money.

“This is about the right to vote,” she said. Currently, when an unmarried woman becomes pregnant, “You can either get married or have an abortion. Why not give people the right to a third choice? “

As education levels have risen in recent years, more and more Chinese women have refused marriage, childbirth, or both. According to government statistics, only 8.1 million couples got married in 2020, the lowest number since 2003.

With the rejection of marriage, the recognition of single mothers has increased. There are no official statistics on single mothers, but a 2018 report by the state-sponsored All-China Women’s Federation estimates that there will be at least 19.4 million single mothers in 2020. These included widowed and divorced women.

When Zhang A Lan, a 30-year-old filmmaker, grew up in Central Hebei Province, unmarried mothers were viewed as defiled and sinful, she said. When she decided to give birth without getting married two years ago, it was common for people on social media to question these old stereotypes.

“Marriage is obviously not a prerequisite for childbirth,” said Ms. Zhang, who gave birth to a boy last year.

Yet many women described a persistent gap between attitudes on the Internet and in reality.

Many Chinese are still concerned about the financial burden and social stigma that single mothers face, said Dong Xiaoying, a Guangzhou lawyer who advocates the rights of single mothers and gay couples. Lesbians are also often denied maternity rights because China does not recognize same-sex unions.

Ms. Dong, who wants to have a child out of wedlock herself, said her parents found the decision incomprehensible.

“It’s a bit like getting out of the closet,” said Ms. Dong, 32. “There’s still a lot of pressure.”

However, the biggest obstacles are official.

The authorities have taken some measures to start recognizing the reproductive rights of single women. A representative of the National People’s Congress, China’s legislature, has for years put forward proposals to improve the rights of unmarried women. While authorities have shut down other feminist groups, those who support unmarried mothers have largely escaped control.

The easier contact with authorities may be due, at least in part, to the fact that women’s goals are aligned with national priorities.

China’s birth rate has declined in recent years after decades of one-child policies severely reduced the number of women of childbearing age. Recognizing the threat to economic growth, the government has begun pushing women to have more children. On Monday, she announced that couples would be allowed to have three children. The government’s latest five-year plan, published last year, promised a more “inclusive” birth policy and raised hopes for recognition of unmarried mothers.

A state outlet was recently mentioned in a headline about the original relaxation of politics in Shanghai: “More and more Chinese cities are offering maternity insurance to unmarried mothers in the demographic crisis.”

But the obvious support only goes so far, said Ms. Dong. Far from promoting women’s empowerment, the authorities have recently attempted to pull women out of the workforce and return to traditional gender roles – the opposite of what single motherhood would allow. “From a governance point of view, they don’t really want to open up completely,” she said.

The National Health Commission emphasized this year that family planning is the responsibility of “husbands and wives together”. In January, the Commission rejected a proposal to open up egg freezing to single women, citing ethical and health concerns.

Open rejection of gender norms can still lead to reprisals. Last month, Douban, a social media site, shut down several popular forums where women discussed their desire not to marry or have children. Site moderators accused the groups of “extremism”, according to group administrators.

Shanghai’s U-turn was the clearest example of the authorities’ mixed message on the reproductive rights of unmarried women.

When the city appeared to be expanding maternity benefits earlier this year, officials never specifically mentioned unmarried women. Their announcement simply said that a “family planning review” that required a marriage certificate would no longer be conducted.

In April women were again asked for their marriage certificates when applying online.

“The local administrators don’t want to take responsibility,” said Ms. Dong. “No higher national authority has said that these family planning rules can be relaxed, so they don’t dare to open that window.”

Many women hope that pressures from an increasingly vocal public will make such regulations untenable.

32-year-old Teresa Xu saw this postponement firsthand in 2019 when she filed a lawsuit against China’s ban on freezing eggs for single women. At first, the judge treated her like a “naive little girl,” she said. But when her case found support on social media, officials became more respectful.

Even so, her case is still pending and officials have not given her an update in over a year. Ms. Xu said she was confident in the long run.

“There’s no way of predicting what they’re going to do in the next two or three years,” she said. “But I think there are some things that cannot be denied when it comes to the development and desires of society. There is no way to reverse this trend. “

Joy Dong contributed to the research.

Newsmax Apologizes for False Claims of Vote-Rigging by a Dominion Worker

Conservative Newsmax officially apologized on Friday for spreading unsubstantiated allegations that a Dominion Voting Systems employee tampered with voting machines to sink President Donald J. Trump’s re-election bid last year.

In a statement posted on its website, Newsmax admitted that it had “found no evidence” of the conspiracy theories put forward by Mr Trump’s lawyers, supporters and others that employee Eric Coomer had Dominion voting machines, voting software and the finals manipulated. When voting, the vote counts.

“On behalf of Newsmax, we apologize for any harm our reporting on the allegations against Dr. Coomer may have caused Dr. Coomer and his family,” the statement said.

Dominion’s director of product strategy and security, Mr. Coomer, sued Newsmax and several pro-Trump figures in December after being flatly defamed in the right-wing media arena. In his lawsuit, which also cites the Trump campaign, Rudolph W. Giuliani, and the One America News Network, Mr. Coomer alleged that he had damaged his reputation, emotional distress, fear, and loss of earnings by making false allegations the entire project would have spread Trump’s world, which he planned to rig the election.

Among the allegations was an allegation that Mr. Coomer said in a phone conversation with anti-fascist activists that he would secure a victory for Joseph R. Biden Jr., the lawsuit said. In fact, Mr Coomer did not attend an “Antifa conference call” and took no action to undermine the presidential election, the lawsuit said.

Even so, hashtags demanding the arrest and exposure of Mr Coomer have been posted on social media. Mr. Trump’s son Eric posted a photo of Mr. Coomer on Twitter, along with the false claim that Mr. Coomer said he would secure a Biden win. Mr. Giuliani, Mr. Trump’s attorney, said at a press conference that Mr. Coomer was a “mean, vicious man” who was “close to Antifa,” the lawsuit said.

And Sidney Powell, who was also one of Mr. Trump’s attorneys, replied, “Yeah, that’s right” on Newsmax when asked if Mr. Coomer said, “Don’t worry about President Trump, I did already assured He will lose the election, ”the lawsuit said.

As a result, Mr. Coomer received an onslaught of abusive messages, harassment and death threats under the lawsuit listing Ms. Powell as a defendant.

“These inventions and attacks against me have changed my life, forced me to flee my home, and made my family and loved ones fear for my safety and I fear for theirs,” Coomer wrote in a published in The Denver Post column in December.

In its statement on Friday, Newsmax said it wanted to “clarify” its coverage of Mr Coomer.

“There are several facts that our viewers should know,” the statement said. “Newsmax has found no evidence that Dr. Coomer interfered in any way with Dominion voting machines or voting software, or that Dr. Coomer ever said so. Neither has Newsmax found any evidence that Dr. Coomer has ever taken part in a conversation with members of the ‘Antifa’, nor that he was directly involved in a party political organization. “

Mr. Coomer’s attorney, Steve Skarnulis, said he could not comment on the statement “because the terms of the settlement are strictly confidential.”

Newsmax said it does not comment on any litigation.

“Our statement on the website is consistent with our previous statements that we saw no evidence of software tampering in the 2020 elections,” said a spokesman for Newsmax.

In December, Newsmax released a statement dispensing with a number of false claims about Dominion and Smartmatic, another voting technology company that has been at the center of conspiracy theories. The statement came after Smartmatic said it had sent Newsmax legal notices and letters demanding withdrawals for posting “false and defamatory statements”.

Newsmax’s statement confirmed that “no evidence was presented that Dominion or Smartmatic used software or reprogrammed software that manipulated the 2020 election vote.”

In February, a Newsmax host, Bob Sellers, interrupted Mike Lindell, the executive director of MyPillow and noisy Trump supporter, as he began attacking Dominion on the air. As Mr. Lindell continued speaking, Mr. Sellers read a prepared statement saying that the election results in each state had been confirmed.

“Newsmax accepts the results as legal and final,” said Sellers. “The courts also supported this view.”

Mr. Coomer’s lawsuit, filed in Colorado, differs from a series of lawsuits that Dominion Voting Systems has filed against Fox News, Mr. Giuliani, and Mr. Lindell.

New York Publish Reporter Who Wrote False Kamala Harris Story Resigns

Ms. Italiano, a veteran postal journalist and long-time chronicler of the New York Courts, is a popular figure on the newspaper’s newsroom. She did not respond to inquiries about her resignation or the making of the Harris Article. Post officials did not respond to calls and emails on Tuesday evening.

In business today

Updated

April 27, 2021 at 5:49 p.m. ET

Her sudden exit underscored some of the tensions currently plaguing the Post, a classic militant city tabloid that served as a means of reporting for former President Donald J. Trump many times during his tenure.

Mr Murdoch, who spoke to Mr Trump frequently, installed a new editor at the tabloid last month, Keith Poole, who previously held a top position in Mr Murdoch’s London newspaper The Sun. At least eight journalists from The Post recently left, including a White House correspondent Ebony Bowden.

Fox News and The Post have long shown a certain symbiosis due to their joint ownership of Murdoch. (Just last week, The Post published a gossip article complaining that Glamor magazine didn’t write articles about female Fox News stars.)

Fox News presenters like Tucker Carlson, Greg Gutfeld and Martha MacCallum discussed the Post article about their programs on Monday. Fox News White House correspondent Peter Doocy quoted “a report in the last few days in the New York Post” before asking White House press secretary Jen Psaki on Monday whether Ms. Harris made “money on her books.” “allegedly distributed in the shelters. Ms. Psaki said she “definitely needs to check” what The Post described in a follow-up story when Ms. Psaki offered “no answers”.

On Tuesday’s Fox & Friends, co-host Ainsley Earhardt told viewers the allegations about the Harris Book were “incorrect” and quoted the Washington Post that morning’s fact-checking column. Also on Tuesday, Fox News updated its article on the Harris Book to determine that only a single copy was seen at the shelter and that it was being shipped as “part of a citywide book and toy drive.”

Fox News has come under fire in the past few days for another false claim aired on the network: President Biden planned to cut American red meat consumption as part of his plan to combat climate change. An on-air graphic from Fox News declared “Bye-Bye Burgers Under Biden’s Climate Plan,” sparking a cycle of outrage from conservative commentators.

Robert F. Kennedy Jr. is barred from Instagram over false coronavirus claims.

Instagram on Wednesday deleted the report by Robert F. Kennedy Jr., the political scion and prominent anti-vaccine activist, for providing false information related to the coronavirus.

“We removed this account because we repeatedly shared debunked claims about the coronavirus or vaccines,” Facebook, which owns Instagram, said in a statement.

Mr. Kennedy, the son of former Senator and US Attorney General Robert F. Kennedy, worked as an environmental attorney for decades but is now better known as a crusader against vaccines. A 2019 study found that two groups, including his nonprofit now called Children’s Health Defense, had funded more than half of the Facebook ads spreading misinformation about vaccines.

During the pandemic, he found an even wider audience on platforms like Instagram, which he had 800,000 followers on. Although Mr Kennedy has said he is not against vaccines while they are safe, he regularly advocates discredited links between vaccines and autism, arguing that it is safer to contract the coronavirus than to get vaccinated against it.

Facebook is becoming more aggressive in its efforts to stamp out misinformation about vaccines, and this week it says it would remove posts with flawed claims about the coronavirus, coronavirus vaccines, and vaccines in general, whether it was paid advertisements or user-generated Posts. In addition to Mr. Kennedy’s Instagram account, the company said it removed eight more Instagram accounts and Facebook pages on Wednesday as part of its updated policy.

They did not include Mr Kennedy’s Facebook page, which was still active early Thursday and making many of the same unfounded claims against more than 300,000 followers. The company said it has not automatically disabled accounts on its platforms and that there are no plans to delete Mr. Kennedy’s Facebook account “at this point.”

Children’s Health Defense did not immediately respond to a request for comment.

Members of Mr. Kennedy’s family have spoken out against his anti-vaccination efforts, including a brother, sister and niece who accused him of “dangerous misinformation” in a column they wrote for Politico in 2019 . Another niece, Kerry Kennedy Meltzer, a New York Presbyterian Hospital / Weill Cornell Medical Center doctor, wrote an opinion piece in the New York Times in December challenging his claims.

“I love my uncle Bobby,” she wrote. “I admire him for many reasons, including his decades of struggle for a cleaner environment. But when it comes to vaccines, he’s wrong. “

Fb says it plans to take away posts with false vaccine claims.

Facebook said Monday that it plans to remove posts with false claims about vaccines from its platform, including repealing claims that vaccines cause autism or that it is safer for people to contract the coronavirus than vaccinations receive.

The social network has increasingly changed its content policies over the past year as the coronavirus has risen sharply. In October, the social network banned people and companies from buying advertisements containing false or misleading information about vaccines. In December, Facebook announced it would remove posts with claims exposed by the World Health Organization or government agencies.

Monday’s move goes even further by targeting unpaid posts to the website and, in particular, to Facebook pages and groups. Rather than just aiming at misinformation about Covid-19 vaccines, the update includes incorrect information about all vaccines. Facebook said it had consulted with the World Health Organization and other leading health institutes to come up with a list of false or misleading claims regarding Covid-19 and vaccines in general.

In the past, Facebook had announced that it would only “rank down” or push down on people’s news feeds, leading to misleading or false claims about vaccines, making it harder to find such groups or posts. Now posts, pages and groups that contain such untruths will be completely removed from the platform.

“Building trust in these vaccines is critical, so we’re launching the world’s largest campaign to help public health organizations share accurate information about Covid-19 vaccines and encourage people to get vaccinated as soon as possible they have vaccines available, “said Kang-Xing Jin, director of health at Facebook, in a company blog post.

The company said the changes were in response to a recent decision by the Facebook Oversight Board, an independent body that reviews decisions made by the company’s policy team and determines whether they are fair. In a decision, the board said Facebook needed to create a new standard for health-related misinformation because its current rules were “inappropriately vague”.

Apr 8, 2021, 7:52 p.m. ET

Facebook also announced that it would provide US $ 120 million in advertising loans to ministries of health, non-governmental organizations and United Nations agencies to help spread reliable Covid-19 vaccines and preventative health information. As vaccination centers became more prevalent, Facebook would help point people to places to get the vaccine.

Mark Zuckerberg, the founder and CEO of Facebook, has been proactive against false information related to the coronavirus. He has Dr. Anthony Fauci, the nation’s leading infectious disease expert, often hosted on Facebook for live video updates on America’s response to coronavirus. In his private philanthropy, Mr. Zuckerberg has also vowed to “eradicate all diseases” and pledge billions to fight viruses and other diseases.

However, Mr Zuckerberg was also a staunch advocate of free speech on Facebook and previously hesitated to contain most falsehoods, even if they were potentially dangerous. The exception was Facebook’s policy of not tolerating statements that could lead to “immediate, direct physical harm” to people on or outside the platform.

Facebook has been criticized for this stance, including for allowing President Donald J. Trump to stay on the platform until after the January 6 uprising in the U.S. Capitol.

Public health advocates and outside critics have questioned Facebook’s refusal to remove false or misleading claims about vaccines for years. This has resulted in an increase in false vaccine information, often by people or groups spreading other harmful misinformation on the website. Even when Facebook tried to update its guidelines, it often left loopholes that were exploited by misinformation spreaders.

Facebook announced on Monday that it was also changing its search tools to post relevant, authoritative results on coronavirus and vaccine information while making it harder to find accounts that are preventing people from getting vaccinated.

False Experiences of a New ‘U.S. Variant’ Got here from White Home Process Pressure

Reports of a highly contagious new variant in the United States released on Friday by several news outlets are based on speculative statements by Dr. Deborah Birx and are inaccurate according to several government officials.

The flawed report arose recently at a meeting at which Dr. Birx, a member of the White House’s coronavirus task force, presented diagrams of the escalating cases in the country. She suggested to other members of the task force that a new, more transferable variant originating in the US could explain the surge, as did another variant in the UK.

Their hypothesis made it a weekly report sent to the state governors. “This fall / winter rise was almost twice as fast as the spring and summer rise. This acceleration suggests that there may be a US variant that has evolved here, on top of the UK variant that is already spreading in our communities and potentially 50% more transferable, ”the report said. “Aggressive attenuation must be used to match a more aggressive virus.”

CDC officials in dismay tried to remove the speculative statements, but were unsuccessful, according to three people familiar with the events.

CDC officials disagreed with their assessment and asked to have them removed, but they were told no, according to a frustrated CDC official who spoke on condition of anonymity for fear of retaliation.

Dr. Birx could not be reached immediately for comment.

News of a possible new variant appeared on CNBC Friday afternoon and quickly spread to other branches. In response to media inquiries about the variant, the CDC issued a formal statement refuting the theory.

“Researchers from the Centers for Disease Control and Prevention are monitoring all emerging variants of the coronavirus, including the 5,700 samples collected in November and December,” said Jason McDonald, an agency spokesman. “So far, neither CDC researchers nor analysts have seen any particular variant emerge in the US,” he said.

Variants in circulation in the US include B.1.1.7, which was first identified in the UK and is now driving a surge and overwhelming hospitals. The variant has been discovered in a handful of states, but the CDC estimates it currently accounts for less than 0.5 percent of cases in the country.

Another variant that circulates in small amounts in the US, known as B 1.346, contains a deletion that can make vaccines less effective. “But I didn’t see anything about increased transmission,” said Michael Worobey, an evolutionary biologist at the University of Arizona who discovered this variant.

This variant has been in the US for three months and also accounts for less than 0.5 percent of cases. Therefore, it is unlikely to be more contagious than other variants, according to a CDC scientist who spoke on condition of anonymity because he was not authorized to speak about the matter.

All viruses evolve and the coronavirus is no different. “Because of the scientific understanding of viruses, it is very likely that many variants will develop simultaneously around the world,” said McDonald of the CDC. “However, it may take weeks or months to determine if there is a single variant of the virus that is causing Covid-19 to fuel the surge in the US, much like the UK.”

Australia Scraps Covid-19 Vaccine That Produced H.I.V. False Positives

Australia on Friday canceled a roughly $ 750 million plan for a major contract for a locally developed coronavirus vaccine after vaccination resulted in false positive test results for HIV in some volunteers participating in an experimental study.

Of the dozen of coronavirus vaccines tested worldwide, the Australian one was the first to be abandoned. While the developers said the experimental vaccine was safe and effective, the false positives risked confidence in efforts to vaccinate the public.

Prime Minister Scott Morrison said Friday that his government would partially offset the loss of 51 million doses it planned to buy from the Australian consortium by increasing orders for vaccines from AstraZeneca and Novavax. The government has announced that it will start vaccinating citizens in March.

“We can’t have problems with trust,” he told reporters, “and now as a nation with a good portfolio of vaccines we are able to make those choices to best protect the Australian people.”

The Australian setback highlighted the missteps that can inevitably occur when scientists shorten the usual year-long process of vaccine development to a few months during a pandemic that killed more than 1.5 million people.

But just as the Australian scientists made their announcement, the fruits of this breed became clearer. The United States got one step closer to getting its first approval for a Covid-19 vaccine when a panel of experts advising the Food and Drug Administration endorsed a Pfizer vaccine that is already in use in the UK.

The problem with the Australian vaccine, developed by the University of Queensland and biotech company CSL, was related to the use of two fragments of a protein found in HIV

The protein was part of a molecular “clamp” that researchers placed on the spikes surrounding the coronavirus and allowed it to penetrate healthy cells. The bracket stabilizes the spikes and allows the immune system to respond more effectively to the vaccine.

Using the HIV protein did not pose a risk of infecting the volunteers with this virus, the researchers said. However, the clamp produced the production of antibodies that were detected by HIV testing at higher levels than scientists expected.

Because HIV tests couldn’t be quickly revised to take this into account, the researchers decided to stop developing the vaccine. The act could have created widespread fears among Australians that the vaccine could cause AIDS.

Early experiments on hamsters showed that the vaccine protected them from the coronavirus. When Phase 1 human trials began in July, the 216 volunteers were “fully informed about the possibility of a partial immune response” to the clamp, the University of Queensland and CSL said in a statement Friday.

Updated

Apr 11, 2020 at 1:26 am ET

The mistake, said John P. Moore, an immunologist at Weill Cornell Medical College in New York, was an “honest mistake” that cost money, not human life.

“I’m sure a lot of people are very embarrassed,” said Professor Moore. “It’s not great to be associated with a bug like this. But when you run at 90 mph, you sometimes trip. “

Things to know about testing

Confused by Coronavirus Testing Conditions? Let us help:

    • antibody: A protein produced by the immune system that can recognize and attach to certain types of viruses, bacteria or other invaders.
    • Antibody test / serology test: A test that detects antibodies specific to the coronavirus. About a week after the coronavirus infects the body, antibodies start appearing in the blood. Because antibodies take so long to develop, an antibody test cannot reliably diagnose an ongoing infection. However, it can identify people who have been exposed to the coronavirus in the past.
    • Antigen test: This test detects parts of coronavirus proteins called antigens. Antigen tests are quick and only take five minutes. However, they are less accurate than tests that detect genetic material from the virus.
    • Coronavirus: Any virus that belongs to the Orthocoronavirinae virus family. The coronavirus that causes Covid-19 is known as SARS-CoV-2.
    • Covid19: The disease caused by the new coronavirus. The name stands for Coronavirus Disease 2019.
    • Isolation and quarantine: Isolation is separating people who know they have a contagious disease from those who are not sick. Quarantine refers to restricting the movement of people who have been exposed to a virus.
    • Nasopharyngeal smear: A long, flexible stick with a soft swab that is inserted deep into the nose to collect samples from the space where the nasal cavity meets the throat. Samples for coronavirus tests can also be obtained with swabs that do not go as deep into the nose – sometimes called nasal swabs – or with mouth or throat swabs.
    • Polymerase chain reaction (PCR): Scientists use PCR to make millions of copies of genetic material in a sample. With the help of PCR tests, researchers can detect the coronavirus even when it is scarce.
    • Viral load: The amount of virus in a person’s body. In people infected with the coronavirus, viral loads can peak before symptoms, if any.

The University of Queensland’s vaccine was one of several vaccines under development that contain a coronavirus protein that triggers an immune system response. Protein-based vaccines have a longer track record than some of the newer approaches used by competing coronavirus vaccines, such as those based on viral genes or called adenoviruses.

Prominent protein-based vaccines include one from Novavax of Maryland, which is in Phase 3 trials, and another from Clover Biopharmaceuticals of China, which is in Phase 1.

In the case of the Australian vaccine, it was found to produce a strong immune response and, according to the scientists in the phase 1 study, did not cause any serious side effects. However, proceeding with the vaccine study would have required “significant changes” in longstanding HIV testing procedures, they said.

“This would delay development for another 12 months, and while this is a difficult decision, the urgent need for a vaccine must be everyone’s priority,” Paul Young, a virologist at the university who directed the vaccine effort, said in the Explanation. He did not immediately respond to a request for comment on Friday afternoon.

Australian Health Secretary Greg Hunt told reporters the country still has access to 140 million units of coronavirus vaccines – more than enough to feed its population of approximately 25 million people.

“This is the scientific process that works,” said Hunt. “It’s the planning process that works. It’s an honest explanation for some of the challenges we’ve faced. “
