The research in question happened in 2016 and was called “W1V1”. Regarding the 2016 work: https://www.technologyreview.com/2021/06/29/1027290/gain-of-function-risky-bat-virus-engineering-links-america-to-wuhan/ https://www.technologyreview.com/2021/06/29/1027290/gain-of-... > Since bat viruses like WIV1 haven’t been confirmed to cause disease in human beings, her biosafety committee recommended BSL-2 for engineering them and testing them and BSL-3 for any animal experiments. > In response to questions about the decision to do the research in BSL-2 conditions, Peter Daszak forwarded a statement from EcoHealth Alliance stating that the organization “must follow the local laws of the countries in which we work” and that the NIH had determined the research was “not gain-of-function.” > The genetic code of SARS-CoV-2 does not resemble that of any virus the WIV was known to be culturing in its lab, such as WIV1, and Baric says he still believes a natural spillover is the most likely cause. This theory is more than a few steps away from being a smoking gun.
