In 2015, Ralph S. Baric, arguably the world’s most experienced coronavirologist, published groundbreaking work with Shi Zhengli, a leading coronavirus specialist at the Wuhan Institute of Virology.
They combined parts of other coronaviruses and created a synthetic virus, or chimera, that can also infect human cells. Studies have helped crystallize the risk posed by bat coronaviruses lurking in the wild. But the experiments were also dangerous. In 2014, while his studies were ongoing, Obama’s administration decreed a pause on so-called gain-of-function studies, which can also increase the virulence or transmissibility of certain viruses. Baric and Shi even pointed out the risks of the studies. themselves, writing: “Scientific review committees would possibly conduct similar studies. . . too risky to be carried out. “
The experiments were conducted in Baric’s well-secured laboratory in Chapel Hill, North Carolina. Thereafter, however, Shi’s team at the WIV continued to use Baric’s study techniques. His paintings were funded in part through a U. S. scholarship.
Baric testified that he, in particular, warned Shi Zhengli that critical studies on the WIV coronavirus were being conducted in laboratories with inadequate biosafety protections.
Amid conflicting theories about the origins of SARS-CoV-2, the virus that causes COVID-19 (adding whether it may have originated in a Wuhan lab), Baric has a figure of great interest. After all, he pioneered the techniques used through WIV, adding one that allows researchers to invisibly link parts of the virus in combination without leaving a trace.
Over the past three years, as the debate over the origins of COVID-19 has become increasingly toxic, a small army of global detectives and data freedom petitioners have targeted Baric’s emails and study papers, hoping to uncover insights into the true functions of genetic engineering. . of the WIV scientists, the ongoing studies they were conducting, and the viral genome sequences they had in their possession before the pandemic.
Despite all this, Baric has remained virtually silent until now. On Jan. 22, he gave a six-hour interview to investigators from two Republican-led House committees: the Special Subcommittee on Oversight and Accountability on the Coronavirus Pandemic and the Energy and Commerce Subcommittee on Oversight and Investigations. While the committees have yet to make their testimony public, Vanity Fair has exclusively reviewed their statements. Although not officially under oath, Baric demanded by federal law that he answer honestly. University of North Carolina-Chapel Hill, Baric declined to comment for this article. )
While there is little in the 212-page transcript that is likely to particularly fit the debate over the origin of COVID-19, the picture that emerges is that of an American scientist who is deeply suspicious of his Chinese counterparts and has no way of doing so. to know if or how they might have used the innovative study techniques he developed.
Perhaps most notably, Baric testified that he, in particular, warned Shi Zhengli that critical studies on the WIV coronavirus were being conducted in laboratories with inadequate biosafety protections. When he suggested that she move the work to a safer Biosafety Level 3 (BSL-3) lab. , testified that she had ignored his recommendation. Because the WIV has continued to conduct coronavirus studies at what it considers a beside the point of biosecurity, Baric said of a lab accident: “You can’t rule that out. . . I just can’t.
“Obviously, the market is a vehicle for expansion,” Baric said. “Is that where it started? I don’t think so. “
In an email given to the select subcommittee as part of its investigation, Baric told Peter Daszak, president of the nonprofit clinical organization EcoHealth Alliance, that “it’s a lot” to recommend that the WIV conduct coronavirus studies in laboratories with sufficient biosafety. .
Baric told congressional investigators that he believes SARS-CoV-2 is much more likely to be transmitted naturally from animals to humans, given the abundance of viruses in nature, but he also said in his testimony that he disagreed with the widely circulating maximum. Contagion argument: That the virus jumped from inflamed animals to other people at the Huanan Seafood Wholesale Market, where it first appeared in December 2019. That argument doesn’t hold water,” he said, because genomic evidence suggests COVID-19 is already circulating. in the human population until mid-October. ” Obviously, the market is a vehicle for expansion,” he said. Is that where you started?I don’t think so. “
Baric also weighed in on a controversy pitting Dr. Anthony Fauci against Sen. Rand Paul (R-KY), who used his credentials as an ophthalmologist to position himself as a crusader opposed to American medical and clinical establishments. Fauci continually denied Paul’s claims that the National Institute of Allergy and Infectious Diseases, which Fauci headed at the time, had funded gain-of-function studies at the WIV. However, Baric told the researchers that the experiment in question, in which technicians created a chimeric virus that made lab mice sicker, was “absolutely” gain-of-function studies: “You can’t argue with that. “He also said he felt the effects of the experiment had triggered a regulatory review.
The federal grant for the experiment in question, which was conducted at the WIV between 2018 and 2019, was channeled through EcoHealth Alliance. It’s Daszak, president of EcoHealth, who organized an open letter in the medical journal Lancet at the start of the pandemic that helped provide speculation about lab leaks as a baseless conspiracy theory. Today, the election subcommittee is expected to release a report calling on the NIH to propose that EcoHealth Alliance, and Daszak personally, be barred from receiving federal funding. As part of its investigation into the origins of COVID-19, the special subcommittee is holding a series of hearings. Daszak is scheduled to testify publicly today and Fauci is expected to do so on June 3.
U. S. intelligence agencies remain divided over whether SARS-CoV-2 originated from an herbal spill or a lab accident. Health and Human Services Secretary Xavier Becerra recently said the query will likely “never” be answered “unless China opens up more. “
The most significant factor that emerges from the pages of Baric’s testimony is his persistent fear of unsafe study practices at the WIV. Some of Shi’s research papers, he said, “actually indicated that they were doing cultivation work under BSL-2. “-3 labs require negative pressure airflow, HEPA air filtration systems, and complete Tyvek coveralls for lab painters, all to protect against leaks. BSL-2 labs do not require specialized air filtration or full gowns.
Throughout his interview, Baric was careful to emphasize to congressional investigators that he hadn’t just entrusted his study techniques to his colleagues at WIV. Referring to his 2015 studies with Shi, he said, “Although we published the approaches on how to build molecular clones of coronaviruses, we never saw anyone from Dr. Shi’s lab or the Wuhan Institute of Virology come into our lab and train. We never teach them.
Its acceptance as true was violated on at least one occasion, he said. To test the ability of other viruses to infect humans, Baric engineered mice whose lungs contained a human gene. Then, during the pandemic, he said he discovered that his mice were being sold through a commercial company. The gains, he told investigators, were “infuriating. “
As Baric told congressional investigators, Shi’s past paintings were “very confusing as to security conditions. They said they were following Chinese regulations. But in two subsequent articles, Baric said, “They stated that they were doing the crop paints under BSL-2. . . . And then they continued like this until September 2020, which I found irresponsible. (Neither Shi Zhengli nor a spokesperson for the Wuhan Institute of Virology responded to requests for comment. )
Baric told the committee that from his early days working with zoonotic coronaviruses, he understood that there was a real, albeit “rare,” possibility that one of them could prove contagious to humans. “And if that’s your guess, then you’re doing it under BSL-3,” he said. “So I kind of establish what’s popular in the United States. “
But the WIV, he said, operated under a more flexible set of biosecurity protocols. “Their regulations make it transparent that they don’t consider virus culture at the BSL-2 point to be a biosecurity issue,” he said. “I also had this I showed verbally through Zhengli Shi during an assembly in Harbin, when I told him that I would have to move everything to BSL-3 and the reasons. “(Less than a year into the pandemic, the Chinese government passed a law strengthening the country’s laboratory protective practices. )
The dispute over biosecurity resurfaced in 2018, when Baric and Shi were applying with Daszak on a grant proposal to collect SARS-like bat coronaviruses and insert a genetic component called a furin cleavage site that would allow them to infect human cells more easily. Since then, it has attracted attention because, when SARS-CoV-2 emerged in Wuhan, it possessed a furin cleavage site, making it unique among SARS-related coronaviruses. The 2018 proposal was submitted through Daszak to the Pentagon’s research and progression agency, DARPA.

Last December, a data freedom think tank called U. S. Right to Know posted comments in the margins of an early draft of the grant proposal. In one of them, Peter Daszak tagged his collaborators and said, “Ralph. Zhengli. Si we win this contract, I’m suggesting that all of these paintings necessarily be done through Ralph, but I need to emphasize the American aspect of this proposal so that DARPA feels comfortable with our team. Once we get the funds, we can divide up who makes what precise paintings, and I think a lot of those analyses can be done in Wuhan as well.
The first edition stipulated that the studies would be conducted at the BSL-2 level, making them “very cost-effective. “Baric objected to this in a side comment: “In the U. S. In the U. S. , those recombinant SARS CoVs are studied under BSL3, not BSL2, which is especially vital for those that can bind to and mirror in early human cells. In China, those viruses can simply spread under BSL2. Most likely, U. S. researchers will panic. In the final proposal, BSL-2 was replaced through BSL-3.
Baric told congressional investigators that he wrote the remark to Daszak in the margin “to make sure he’s paying attention to it. “He added, “First of all, I would like to inform you, in case you don’t know, that a lot of the virus discoveries and cultural paintings that the Chinese are making with zoonotic coronaviruses are being made at BSL-2. . . I let him know that there is a difference.
After a congressional investigator observed, “There seems to have been a willingness, not necessarily on your part, to do some of this work on BSL-2 in China,” Baric responded, “There is no will on my part to do anything. “These paintings. . . . Let me be clear. He went on to explain, “My role is to examine some viruses that the Wuhan Institute of Virology found they were willing to share with me. “
DARPA rejected the grant, but questions remain about whether WIV scientists still conducted the proposed studies. Baric told congressional investigators that he didn’t know if the WIV had continued studies or obtained other funding. 2 was designed and dismissed by a 2022 paper calling this argument “biostatistical nonsense. “Alex Washburne, one of the paper’s authors, told Vanity Fair, “Baric does not provide any clinical evidence or reasoning that would lead us to revise our effects or replace them. “our theory. “
In May 2021, Baric signed an open letter in the journal Science arguing that the lab and herbal hypotheses are viable and calling for further research. A fellow scientist, Columbia University virologist Ian Lipkin, asked him why he had signed the letter. In response, Baric told the subcommittee: “I sent you a couple of papers that the Chinese had published in which they were doing virus discovery work under BSL-2 conditions, which is one of the main reasons why I felt that possible speculation about a lab leak in essence, should not be swept under the rug.
“You think it was a proper block if necessary, but don’t expect it to do it,” Baric wrote to Daszak. “Also, don’t insult my intelligence by seeking to feed me with all this. “
Baric’s signing of that letter also led to an awkward email exchange with Daszak about the WIV’s protection criteria, received through Vanity Fair. Daszak informed Baric of the various tactics in which the protection criteria of Chinese laboratories were not far from the American criteria. He added: “We checked with Zhengli, who informed us that they were employing ‘BSL-2 with negative voltage and suitable EPI’.
This provoked a scathing reaction from Baric. “BSL2 with negative pressure, give me a break. ” He noted that even Shi’s most recent articles never described the protective precautions used. “Yes, China has the right to outline its own policy. You think it was a correct block if necessary, but don’t expect me to do it. “it. Also, don’t insult my intelligence by seeking to feed me with all this.
When contacted for comment, Daszak told Vanity Fair that the WIV conducted its animal infection experiments “on BSL-3, according to paintings from Dr. Baric’s lab in the United States. “He also said that studies rejected through DARPA “have never been conducted” and that the proposal called for only paintings “that do not involve any infectious material” to be done at a BSL-2 facility at the WIV. Regarding the subcommittee’s call for the NIH to propose barring him and EcoHealth Alliance from receiving federal funding, he said he hadn’t noticed the report yet and may not have commented on it. However, he said EcoHealth Alliance has “fully and promptly cooperated with the NIH on new oversight measures since 2020” and shared a letter from last October that the NIH is the nonprofit organization that meets oversight requirements.
Another signatory of the May 2021 letter was Dr. Michael Worobey, who has since been one of the leading proponents of the theory that the virus spreads from inflamed animals at the Huanan Seafood Wholesale Market.
In 2022, Worobey and a team of foreign scientists published an influential paper on geospatial studies of early infections in Wuhan to make the case for the market consequences theory. Using knowledge gathered through Chinese scientists, Worobey’s team also later published evidence in a preprint showing that virus-susceptible mammals, such as raccoon dogs, were being offered on the market.
When leading virologists claim that the preponderance of evidence points to a natural origin, they are referring to Worobey’s research. Baric, for his part, told congressional investigators that Woroney’s geospatial survey had a “big problem” with its timing. He told the subcommittee: “The only thing we have a solid understanding of is that the market was the site of an amplification last December, January. It’s been another two months since the original date, according to a molecular clock, meaning it was circulating somewhere before. It was given there. And the question is: where was he?
Baric said the first cases were “almost impossible” to document because many were asymptomatic. “That’s a basic challenge with articles that aim to solve it: I think they write things that are too strong, but they’re very passionate about their knowledge. And to be fair to them, it’s the most productive knowledge there is. He went on to criticize the newspapers’ claim that two independent jumps of other inflamed animals on the market were based on the presence of two other lineages of the virus. “It’s exaggerated,” he said, adding that his view is shared by “a lot of virologists who look at this knowledge and say, um. “
Worobey called the evidence for the origin of an ad “powerful” and told Vanity Fair that he believes the first animal-to-human jump happened in November. Baric, he said, “has virtually no experience in the subjects of the articles he discusses. . . . . . It’s irresponsible of you to share those reviews with someone without also making it clear that you’re in no better position than the average informed user to make a judgment about this work.
In his testimony, Baric was ambiguous about whether the WIV scientists could have possessed SARS-CoV-2, or a very close ancestor, before the pandemic. There is “evidence that they were construction chimeras” and “did discovery work on the purposes of the beak. “genes from the zoonotic strains they discovered later, but I don’t know if they did any engineering or anything like that. “
Without additional revelations from China, the answer would possibly be unknowable. As Baric told the congressional researchers: “If you had to consult the laboratory notebooks, if you had to consult the protection records of the Wuhan Institute of Virology, if you had to consult the series databases, the point of security you would have would be greater. Not at all. “
“What didn’t we have?” asked a congressional investigator.
“Which we don’t have,” Baric responded. “That’s very true”.
