Opinion | The Government Must Say What It Knows About Covid’s Origins

The names of the researchers who reportedly fell ill, which have not been publicly confirmed by the U.S. government and therefore remain unverified, and the nature of their work, were disclosed last week by the news site Public. One of those named researchers, Ben Hu, is a leading scientist who has worked on bat coronaviruses related to SARS. Some of Hu’s work was funded by the U.S. government, a fact that was unearthed through Freedom of Information Act requests by the nonprofit group White Coat Waste Project, which opposes taxpayer-funded research on animals, as well as by The Intercept, which uncovered broader U.S. funding for potentially dangerous lab work in Wuhan.

Another researcher who reportedly fell sick, Yu Ping, had written a thesis in 2019 about work at the virology institute on bat coronaviruses related to SARS — a thesis that was unearthed by a group of independent researchers who call themselves DRASTIC The thesis further confirmed that work on these dangerous viruses was being done in labs with the second-lowest level of biosafety, BSL-2.

In September 2021, DRASTIC also obtained a funding proposal that the Wuhan Institute of Virology’s U.S. collaborator, EcoHealth Alliance, submitted to the Pentagon’s Defense Advanced Research Projects Agency. The proposal called for using genetic engineering to perform experiments with bat SARS-like coronaviruses and modify them by inserting features that can increase their ability to infect humans. The U.S. government rejected the proposal. One of the things that the scientists were proposing to do was to insert into these SARS-like viruses what is called a “furin cleavage site” — a feature of the Covid virus, but of no other known member of its subgenus.

The feature could also have evolved naturally, and many scientists dismissed its significance as evidence that research set off the pandemic origins. In a September 2021 journal article, published just before the grant application was made public, 21 scientists wrote that there was no evidence of research at the Wuhan Institute of Virology “involving the artificial insertion of complete furin cleavage sites into coronaviruses.” So the grant application, which calls that claim into question, is significant.

Thanks to extensive public records requests by the nonprofit group U.S. Right to Know, we are also aware that, as early as February 2020, many scientists who were publicly ruling out any role that research could have played in the pandemic, were privately expressing concern that there was a such connection, and in fact were specifically worried about the unusual furin cleavage site. (Some of the scientists have said they later changed their minds).
