Artem S. Tashkinov shares a report from Ars Technica: Health regulators in Brazil say that doses of Russia's Sputnik V COVID-19 vaccine contain a cold-causing virus capable of replicating in human cells. The unintended presence of the virus in the vaccine can "lead to infections in humans and can cause damage and death, especially in people with low immunity and respiratory problems, among other health problems," Brazil's Health Regulatory Agency, Anvisa, said Wednesday in a translated statement. Russia has unequivocally denied the claim, lobbed legal threats at Anvisa, and accused the respected regulators of being politically motivated to reject the vaccine. Still, Brazil's findings raise serious questions about the quality and safety of the vaccine, which is now being used in many countries. The findings also support concerns of Slovak regulators, who said earlier this month that batches of Sputnik V they received did not "have the same characteristics and properties" as the Sputnik V vaccine that was described in a peer-reviewed publication and found to be 91.6 percent effective.

Moreover, quality-control issues weren't the end of Anvisa's concerns. In an overall evaluation of the Russian vaccine, Brazil's regulators found its safety and efficacy were based on insufficient, limited, and sometimes faulty data and analyses. "Flaws... were identified in all stages of clinical studies," Anvisa said. The agency also reported that its inspectors who traveled to Russia to assess the vaccine's production were barred from vaccine facilities at Gamaleya Institute, which developed Sputnik V. Russia touts that "the safety and efficacy of Sputnik V has been confirmed by 61 regulators in countries where the vaccine has been authorized." However, Brazil's regulators said that of the 51 countries it contacted, only 14 were using the vaccine, and most of those countries did not have a tradition of vigilant drug-safety monitoring.

An anonymous reader quotes a report from Scientific American: Since the novel coronavirus began its global spread, influenza cases reported to the World Health Organization have dropped to minuscule levels. The reason, epidemiologists think, is that the public health measures taken to keep the coronavirus from spreading also stop the flu. Influenza viruses are transmitted in much the same way as SARS-CoV-2, but they are less effective at jumping from host to host. As Scientific American reported last fall, the drop-off in flu numbers was both swift and universal. Since then, cases have stayed remarkably low. "There's just no flu circulating," says Greg Poland, who has studied the disease at the Mayo Clinic for decades. The U.S. saw about 600 deaths from influenza during the 2020-2021 flu season. In comparison, the Centers for Disease Control and Prevention estimated there were roughly 22,000 deaths in the prior season and 34,000 two seasons ago.

Because each year's flu vaccine is based on strains that have been circulating during the past year, it is unclear how next year's vaccine will fare, should the typical patterns of the disease return. [...] Public health experts are grateful for the reprieve. Some are also worried about a lost immune response, however. If influenza subsides for several years, today's toddlers could miss a chance to have an early-age response imprinted on their immune system. That could be good or bad, depending on what strains circulate during the rest of their life. For now, future flu transmission remains a roll of the dice.

Americans who have been fully vaccinated against COVID-19 can safely do many outdoor activities without wearing a mask, according to updated guidance Tuesday from the US Centers for Disease Control and Prevention. However, health officials said vaccinated people should continue to wear a mask indoors and at crowded outdoor events, such as concerts, parades and sports events. From a report: "There are many situations where fully vaccinated people do not need to wear a mask, particularly if they are outdoors," said CDC Director Dr. Rochelle Walensky during a press briefing. "If you are fully vaccinated and want to attend a small outdoor gathering with people who are vaccinated and unvaccinated or dine at an outdoor restaurant with friends form multiple households, the science shows -- if you're vaccinated -- you can do so safely unmasked."

The CDC released a graphic to help people make decisions about when to wear a mask both outdoors and indoors. For fully vaccinated people, the CDC says these outdoor activities are safe without a mask: Walk, run or bike outdoors with members of your household. Attend a small, outdoor gathering with fully vaccinated family and friends. Attend a small, outdoor gathering with fully vaccinated and unvaccinated people. Dine at an outdoor restaurant with friends from multiple households.

HealthDay reports: There's no evidence of genetic damage in the children of parents who were exposed to radiation from the 1986 Chernobyl Nuclear Power Plant disaster in Ukraine, researchers say.

Several previous studies have examined the risks across generations of radiation exposure from events such as this, but have yielded inconclusive results. In this study, the investigators analyzed the genomes of 130 children and parents from families where one or both parents were exposed to radiation due to the Chernobyl accident, and where children were conceived afterward and born between 1987 and 2002.

There was no increase in gene changes in reproductive cells of study participants, and rates of new germline mutations were similar to those in the general population, according to a team led by Meredith Yeager of the U.S. National Cancer Institute, in Rockville, Md.

An anonymous reader shares an excerpt from a Science Magazine blog, written by Derek Lowe: Excellent news today: we have word of the most effective malaria vaccine yet discovered. A year-long trial in Burkina Faso has shown 77% efficacy, which is by far the record, and which opens the way to potentially relieving a nearly incalculable burden of disease and human suffering.

This new vaccine (R21) uses a circumsporozoite protein (CSP) antigen -- that's a highly conserved protein of the parasite, involved in several functions as the parasite makes the move from mosquito to human and into different human tissues such as the salivary glands. This has been a vaccine ingredient before, such as in the RTS,S vaccine (the first one ever licensed), but R21 has a much higher proportion of CSP assembled into a virus-like particle. It also uses the exact same adjuvant from Novavax (Matrix-M) that they are using in their coronavirus vaccine -- you can't keep a good adjuvant down, and this Chilean-soapbark-based one seems to really kick the immune system up under all circumstances.

The higher-adjuvant cohort showed 77% vaccine efficacy, and the lower-adjuvant one showed 74% with (as you'd expect) overlapping confidence intervals. The first group had significantly higher antibody levels, though, and they're currently doing an additional year of follow-up to see how long the protection lasts and if these doses differentiate themselves. The antibody levels at the one-year mark in both groups were significantly higher than with the RTS,S vaccine, and in particular, antibodies against the repeat section in the middle of the circumsporozite protein seemed to correlate strongly with protection. No safety problems so far. The team is now planning a larger Phase III at five different African site, with varying seasonality and malaria loads.

India reported a global record of more than 314,000 new infections Thursday as a grim coronavirus surge hits the world's second-most populous country, sending more and more sick people into a fragile health care system critically short of hospital beds and oxygen. From a report: The 314,835 infections added in the past 24 hours raise India's total past 15.9 million cases since the pandemic began. It's the second-highest total in the world next to the United States. India has nearly 1.4 billion people. A large number of hospitals are reporting acute shortages of beds and medicine and are running on dangerously low levels of oxygen. The New Delhi High Court on Wednesday ordered the government to divert oxygen from industrial use to hospitals to save people's lives.

"You can't have people die because there is no oxygen. Beg, borrow or steal, it is a national emergency," the judges said responding to a petition by a New Delhi hospital seeking its intervention. The government is rushing oxygen tankers to replenish supplies to hospitals. India's Health Minister Harsh Vardhan said on Thursday that "demand and supply is being monitored round the clock." He said in a tweet that to address the exponential spike in demand, the government has increased the quota of oxygen for the worst-hit seven states. The surge has brought pain, fear and agony to many lives in New Delhi and other cities. In scenes familiar across the country, ambulances are seen rushing from one hospital to another, trying to find an empty bed. Grieving relatives are lining up outside crematoriums where the arrival of dead bodies has jumped several times.

An anonymous reader quotes a report from The New York Times: The European Union unveiled strict regulations on Wednesday to govern the use of artificial intelligence, a first-of-its-kind policy that outlines how companies and governments can use a technology seen as one of the most significant, but ethically fraught, scientific breakthroughs in recent memory. The draft rules would set limits around the use of artificial intelligence in a range of activities, from self-driving cars to hiring decisions, bank lending, school enrollment selections and the scoring of exams. It would also cover the use of artificial intelligence by law enforcement and court systems -- areas considered "high risk" because they could threaten people's safety or fundamental rights.

Some uses would be banned altogether, including live facial recognition in public spaces, though there would be several exemptions for national security and other purposes. The108-page policy is an attempt to regulate an emerging technology before it becomes mainstream. The rules have far-reaching implications for major technology companies that have poured resources into developing artificial intelligence, including Amazon, Google, Facebook and Microsoft, but also scores of other companies that use the software to develop medicine, underwrite insurance policies and judge credit worthiness. Governments have used versions of the technology in criminal justice and the allocation of public services like income support. Companies that violate the new regulations, which could take several years to move through the European Union policymaking process, could face fines of up to 6 percent of global sales.

The European Union regulations would require companies providing artificial intelligence in high-risk areas to provide regulators with proof of its safety, including risk assessments and documentation explaining how the technology is making decisions. The companies must also guarantee human oversight in how the systems are created and used. Some applications, like chatbots that provide humanlike conversation in customer service situations, and software that creates hard-to-detect manipulated images like "deepfakes," would have to make clear to users that what they were seeing was computer generated. [...] Release of the draft law by the European Commission, the bloc's executive body, drew a mixed reaction. Many industry groups expressed relief that the regulations were not more stringent, while civil society groups said they should have gone further.

Governor Andrew Cuomo signed a bill on Friday requiring all Internet service providers in New York to offer affordable high-speed access for low-income families. From a report: The providers can charge those families no more than $15 a month, Cuomo said during a briefing Friday at the Northland Workforce Training Center in Buffalo. He was joined by Eric Schmidt, former chief executive officer of Alphabet, who chairs a 15-member state commission focusing on using technology to help the state reopen better than it was before the virus. Cuomo also said an emergency fund from Schmidt Futures and the Ford Foundation will provide free Internet access to 50,000 students statewide through the 2021-22 school year.

The bill passed by the state legislature caps a basic broadband plan at $15 a month and a higher-speed one at $20. Currently, a basic high-speed plan costs on average more than $50 a month, according to a statement from Assembly member Amy Paulin. Schmidt, who praised the embattled governor for his "extraordinary" leadership during the pandemic, said universal broadband access is the first and most important priority of the commission. Members were concerned about the "hundreds of thousands of people who apparently had no Internet access at all," Schmidt said, an impediment to learning and tele-medicine.

Pfizer CEO Albert Bourla said people will "likely" need a booster dose of a Covid-19 vaccine within 12 months of getting fully vaccinated. His comments were made public Thursday but were taped April 1. From a report: Bourla said it's possible people will need to get vaccinated against the coronavirus annually. "A likely scenario is that there will be likely a need for a third dose, somewhere between six and 12 months and then from there, there will be an annual revaccination, but all of that needs to be confirmed. And again, the variants will play a key role," he told CNBC's Bertha Coombs during an event with CVS Health. "It is extremely important to suppress the pool of people that can be susceptible to the virus," Bourla said. The comment comes after Johnson & Johnson CEO Alex Gorsky told CNBC in February that people may need to get vaccinated against Covid-19 annually, just like seasonal flu shots. Researchers still don't know how long protection against the virus lasts once someone has been fully vaccinated.

An anonymous reader quotes a report from Ars Technica: Cases of COVID-19 are extremely rare among people who are fully vaccinated, according to a new data analysis by the Centers for Disease Control and Prevention. Among more than 75 million fully vaccinated people in the US, just around 5,800 people reported a "breakthrough" infection, in which they became infected with the pandemic coronavirus despite being fully vaccinated. The numbers suggest that breakthroughs occur at the teeny rate of less than 0.008 percent of fully vaccinated people -- and that over 99.992 percent of those vaccinated have not contracted a SARS-CoV-2 infection.

The figures come from a nationwide database that the CDC set up to keep track of breakthrough infections and monitor for any concerning signs that the breakthroughs may be clustering by patient demographics, geographic location, time since vaccination, vaccine type, or vaccine lot number. The agency will also be keeping a close eye on any breakthrough infections that are caused by SARS-CoV-2 variants, some of which have been shown to knock back vaccine efficacy. [...] The extraordinary calculation that 99.992 percent of vaccinated people have not contracted the virus may reflect that they all simply have not been exposed to the virus since being vaccinated. Also, there are likely cases missed in reporting. Still, the data is a heartening sign. As for the "breakthroughs," the agency says many of them occurred in older people, who are more vulnerable to COVID-19. There are some scattered through every age group, but more than 40 percent were in people ages 60 and above.

"We see [breakthroughs] with all vaccines," top infectious disease expert Anthony Fauci said in a press briefing earlier this week. "No vaccine is 100 percent efficacious or effective, which means that you will always see breakthrough infections regardless of the efficacy of your vaccine."

Researchers at the University of Washington have partnered with Apple to study how Apple Watch may be used to predict illnesses such as coronavirus, or flu. Apple Insider reports: "The goal of the study is to see if the information collected by the Apple Watch and iPhone can detect early signs of respiratory illnesses like COVID-19," say the organizers on the recruitment page. The study is focusing on the Seattle area because residents "may have higher than normal risk of respiratory illness because of frequent exposure to other people through work or other activities, health conditions, or other factors."

This Apple Respiratory Study is expected to take "up to six months." During the study, participants will be required to periodically answer survey questions in the Apple Research iPhone app. If participants get sick while enrolled in the study, they will be sent an in-home testing kit for COVID-19 and other respiratory illnesses. But, this will likely assist the study further, as sick participants will be asked to "take some additional health measurements using your Apple Watch."

If your heart stops en route to Mars, rest assured that researchers have considered how to carry out CPR in space. (One option is to plant your feet on the ceiling and extend your arms downwards to compress the patient's chest.) From a report: Astronauts, because of their age range and high physical fitness, are unlikely to suffer a stroke or have their appendix suddenly explode. That's good because, if it does happen, they're in the realm of what Jonathan Scott -- head of the medical projects and technology team at the European Space Agency -- describes as 'treatment futility.' In other words: there's nothing anyone can do about it. On the ISS, when medical incidents arise, astronauts can draw on the combined expertise of a host of medical experts at Nasa. "The patient is on the space station, the doctor is on the ground, and if there's a problem the patient consults the doctor," says Scott. By the time astronauts reach Mars, there'll be a 40-minute time lag in communications, if it's possible to make contact at all. "We have to begin preparing for not only being able to diagnose things in spaceflight but also to treat them as well," Scott says.

Artificial intelligence is likely to be a part of the solution. If you're imagining the holographic doctor from Star Trek, downgrade your expectations, at least for the next few decades. Kris Lehnhardt, the element scientist for exploration medical capability at Nasa, says: "We are many, many, many years away from: please state the nature of the medical emergency." Emmanuel Urquieta is deputy chief scientist at the Translational Institute for Space Health (TRISH), a Nasa-funded program which conducts research into healthcare for deep space missions. While full AI may be a way off, Urquieta believes some form of artificial intelligence will still play a crucial role. "It's going to be essential for a mission to Mars," he says. While the crew for a mission to Mars will likely include a medical doctor, he explains: "No single physician can know everything." And, of course: "What happens if that astronaut gets sick?" Research projects funded by TRISH include Butterfly iQ, a handheld ultrasound device for use by non-medical personnel to make diagnoses that would otherwise require bulky equipment and a trained operator. VisualDx is an AI diagnostics tool originally developed to analyse images and identify skin conditions. The technology is now being adapted to help astronauts diagnose a wide range of conditions most commonly encountered in space, without an internet connection.

Long-time Slashdot reader destinyland writes: The New York Times tells the story of Hungarian-born Dr. Kariko, whose father was a butcher and who growing up had never met a scientist — but knew they wanted to be one. Despite earning a Ph.D. at Hungary's University of Szeged and working as a postdoctoral fellow at its Biological Research Center, Kariko never found a permanent position after moving to the U.S., "instead clinging to the fringes of academia."

Now 66 years old, Dr. Kariko is suddenly being hailed as "one of the heroes of Covid-19 vaccine development," after spending an entire career focused on mRNA, "convinced mRNA could be used to instruct cells to make their own medicines, including vaccines."
From the article: For many years her career at the University of Pennsylvania was fragile. She migrated from lab to lab, relying on one senior scientist after another to take her in. She never made more than $60,000 a year... She needed grants to pursue ideas that seemed wild and fanciful. She did not get them, even as more mundane research was rewarded. "When your idea is against the conventional wisdom that makes sense to the star chamber, it is very hard to break out," said Dr. David Langer, a neurosurgeon who has worked with Dr. Kariko... Kariko's husband, Bela Francia, manager of an apartment complex, once calculated that her endless workdays meant she was earning about a dollar an hour.
The Times also describes a formative experience in 1989 with cardiologist Elliot Barnathan: One fateful day, the two scientists hovered over a dot-matrix printer in a narrow room at the end of a long hall. A gamma counter, needed to track the radioactive molecule, was attached to a printer. It began to spew data.

Their detector had found new proteins produced by cells that were never supposed to make them — suggesting that mRNA could be used to direct any cell to make any protein, at will.

"I felt like a god," Dr. Kariko recalled.
Yet Kariko was eventually left without a lab or funds for research, until a chance meeting at a photocopying machine led to a partnership with Dr. Drew Weissman of the University of Pennsylvania: "We both started writing grants," Dr. Weissman said. "We didn't get most of them. People were not interested in mRNA. The people who reviewed the grants said mRNA will not be a good therapeutic, so don't bother.'" Leading scientific journals rejected their work. When the research finally was published, in Immunity, it got little attention... "We talked to pharmaceutical companies and venture capitalists. No one cared," Dr. Weissman said. "We were screaming a lot, but no one would listen."

Eventually, though, two biotech companies took notice of the work: Moderna, in the United States, and BioNTech, in Germany. Pfizer partnered with BioNTech, and the two now help fund Dr. Weissman's lab.

sciencehabit shares a report from Science Magazine: Experiments that create tiny brainlike structures from human stem cells or transplant human cells into an animal's brain have made some scientists, ethicists, and religious leaders uneasy in recent years. And the National Institutes of Health (NIH) has restricted some of this research. Now, a U.S. scientific panel has weighed in with advice about how to oversee this controversial and fast-moving area of neuroscience. The panel finds little evidence that brain "organoids" or animals given human cells experience humanlike consciousness or pain, and concludes current rules are adequate for overseeing this work. But they caution that could change, particularly as experiments move into nonhuman primates. "The rationale for the report is to get out ahead of the curve," says Harvard University neuroscientist Joshua Sanes, co-chair of the National Academies of Sciences, Engineering, and Medicine committee that released its report today.

Researchers at the Queen Mary University of London have shown that you can collect "environmental DNA" (eDNA) from the air. Engadget reports: The team used a peristaltic pump combined with pressure filters to grab samples of naked mole rat DNA for five to 20 minutes, and then used standard kits to find and sequence genes in the resulting samples. This method not only pinpointed the mole rats' DNA (both in their housing and in the room at large), but caught some human DNA at the same time.

Lead author Dr. Elizabeth Claire said the work was originally meant to help conservationists and ecologists study biological environments. With enough development, though, it could be used for considerably more. Forensics units could pluck DNA from the air to determine if a suspect had been present at the scene of a crime. It might also be useful in medicine -- virologists and epidemiologists could understand how airborne viruses (like the one behind COVID-19) spread.

hackingbear shares a report from The Guardian: Residents [in the Canadian province of New Brunswick] first learned of the investigation last week after a leaked memo from the province's public health agency asked physicians to be on the lookout for (neurological) symptoms similar to Creutzfeldt-Jakob disease (CJD). For more than a year public health officials have been tracking a "cluster" of 43 cases of suspected neurological disease in the province with no known cause. Despite the initial similarities, screening produced no confirmed cases of CJD, a rare, fatal brain disease caused by misformed proteins known as prions. Only a single suspected case was recorded in 2015, but in 2019 there were 11 cases and 24 in 2020. Researchers believe five people have died from the illness. Health officials have refused to disclose the precise locations of the cases. "The majority of cases are linked to the Acadian peninsula, a sparsely populated region in the north-eastern part of the province," the report says. Some of the symptoms include memory loss, vision problems, abnormal jerking movements, unexplained pains, spasms and behavioral changes.

An anonymous reader quotes a report from Motherboard: Stanford scientists saved drops of the COVID-19 vaccine destined for the garbage can, reverse engineered them, and have posted the mRNA sequence that powers the vaccine on GitHub for all to see. The GitHub post is four pages long. The first two are an explanation by the team of scientists about the work, the second two pages are the entire mRNA sequence for the Moderna COVID-19 vaccine. "RNA vaccines have become a key tool in moving forward through the challenges raised both in the current pandemic and in numerous other public health and medical challenges," the scientists said on GitHub. "Despite their ubiquity, sequences are not always available for such RNA. Standard methods facilitate such sequencing."

According to Stanford scientists Andrew Fire and Massa Shoura, this isn't technically "reverse-engineering" a vaccine. "We didn't reverse engineer the vaccine. We posted the putative sequence of two synthetic RNA molecules that have become sufficiently prevalent in the general environment of medicine and human biology in 2021," they told Motherboard in an email. "As the vaccine has been rolling out, these sequences have begun to show up in many different investigational and diagnostic studies. Knowing these sequences and having the ability to differentiate them from other RNAs in analyzing future biomedical data sets is of great utility." [...] According to Shoura and Fire, the FDA cleared the Stanford project's decision to share the sequence with the community. "We did contact Moderna a couple of weeks ago to indicate that we were hoping to include the sequence in a publication and asking if there was anything that we should reference with respect to this... no response or objection from them, so we assume that everyone is busy doing important work."

"The idea of artificially cooling the planet to blunt climate change — in effect, blocking sunlight before it can warm the atmosphere — got a boost on Thursday when an influential scientific body urged the U.S. government to spend at least $100 million to research the technology," reports the New York Times: That technology, often called solar geoengineering, entails reflecting more of the sun's energy back into space through techniques that include injecting aerosols into the atmosphere. In a new report, the National Academies of Sciences, Engineering, and Medicine said that governments urgently need to know whether solar geoengineering could work and what the side effects might be.

"Solar geoengineering is not a substitute for decarbonizing," said Chris Field, director of the Woods Institute for the Environment at Stanford University and head of the committee that produced the report, referring to the need to emit less carbon dioxide and other greenhouse gases into the atmosphere. Still, he said, technology to reflect sunlight "deserves substantial funding, and it should be researched as rapidly and effectively as possible." The report acknowledged the risks that have made geoengineering one of the most contentious issues in climate policy. Those risks include upsetting regional weather patterns in potentially devastating ways, for example by changing the behavior of the monsoon in South Asia; relaxing public pressure to reduce greenhouse gas emissions; and even creating an "unacceptable risk of catastrophically rapid warming" if governments started reflecting sunlight for a period of time, and then later stopped.

But the authors argue that greenhouse gas emissions are not falling quickly enough to avoid dangerous levels of global warming, which means the world must begin to examine other options. Evidence for or against solar geoengineering, they found, "could have profound value" in guiding decisions about whether to deploy it.

While President Trump's former CDC director says he still thinks SARS-Cov-2 somehow originated from a lab in China, "a team of experts from the World Health Organization, Dr. Anthony Fauci, and a number of virology experts have said the evidence to support such a claim just isn't there," reports CBS News: Redfield, a virologist who headed the CDC under President Trump, stressed several times that this is just his opinion, not a proven fact. "I'm allowed to have opinions now," he said... Dr. Anthony Fauci addressed Redfield's comments at Friday's COVID-19 response briefing and suggested that most public health officials disagree.... Kristian G. Andersen, director of the infectious disease genomics, translational research institute at Scripps Research, told CBS News that "none of (Redfield's) comments" on the lab theory are "backed by available evidence."

"It is clear that not only was he the most disastrous CDC director in U.S. history where he utterly failed in his sworn mission to keep the country safe, but via his comments, he also shows a complete lack of basic evolutionary virology," Andersen said.

Andersen was the lead author of a study published in Nature Medicine last year which found that the virus was a product of natural evolution. Furthermore, through analysis of public genome sequence data, the scientists "found no evidence that the virus was made in a laboratory or otherwise engineered," according to a press release from Scripps. "By comparing the available genome sequence data for known coronavirus strains, we can firmly determine that SARS-CoV-2 originated through natural processes," Andersen said at the time. W. Ian Lipkin, a study co-author with Andersen and the director of the Center for Infection and Immunity at Columbia's Mailman School of Public Health, said that while there's still a lot we don't know about the virus, including exactly how long it's been circulating, there is "no evidence" to suggest that it was created in a lab...

Andersen noted that "We know that the first epidemiologically linked cluster of cases came from the Huanan market and we know the virus was found in environmental samples — including animal cages — at the market," he said. "Any 'lab leak' theory would have to account for that scenario — which it simply can't, without invoking a major conspiracy and cover up by Chinese scientists and authorities."

His scathing conclusion: "Redfield has no idea what he's talking about — plain and simple. It's no surprise given his disastrous tenure as CDC director."

Beeftopia shares a report from Axios: Former CDC Director Robert Redfield told CNN on Friday that he believes the coronavirus "escaped" from the Wuhan Institute of Virology, and that it was spreading as early as September or October of 2019 -- though he stressed that it was his "opinion." "I'm of the point of view that I still think the most likely etiology of this pathology in Wuhan was from a laboratory. Escaped. Other people don't believe that. That's fine. Science will eventually figure it out," Redfield told CNN's Sanjay Gupta... "That's not implying any intentionality. It's my opinion, right...?"
Axios calls it "a stunning assertion, offered with little evidence," even though Redfield "is a career virologist," argues Slashdot reader Beeftopia. "He received his medical degree from Georgetown University before conducting his residency at the Walter Reed Army Medical Center as a US Army officer. Both of his parents were scientists at the National Institutes of Health. Before starting his position as the director of the CDC, Redfield was a professor at the University of Maryland School of Medicine and was once one of the US Army's leading AIDS researchers. He does have a controversial incident regarding an AIDS vaccine on which his lab was working." In fact, Kaiser Health News reports Redfield had been the principal investigator for clinical trials of a treatment vaccine: "Either he was egregiously sloppy with data or it was fabricated," said former Air Force Lt. Col. Craig Hendrix, a doctor who is now director of the division of clinical pharmacology at Johns Hopkins University School of Medicine. "It was somewhere on that spectrum, both of which were serious and raised questions about his trustworthiness...." Washington Senator Patty Murray, the ranking Democrat on the health committee, cited the research controversy as an example of a "pattern of ethically and morally questionable behavior" by Redfield that should prompt the president to reconsider the appointment.
Earlier this month, a member of the WHO investigative team said wildlife farms in southern China are the most likely source of the COVID-19 pandemic. Peter Daszak, a disease ecologist with EcoHealth Alliance and part of the WHO delegation that traveled to China earlier this year, told NPR that the Chinese government thought those farms were the most probable pathway for a coronavirus in bats in southern China to reach humans in Wuhan.
