NIH says grantee failed to report experiment in Wuhan that created a bat virus that made mice sicker

An ongoing controversy over what constitutes virology research that is too dangerous to conduct—and whether the U.S government funded studies in China that violated a policy barring funding for such risky research—has taken a new turn. While denying once again it had helped create the virus that sparked the COVID-19 pandemic, the U.S. National Institutes of Health (NIH) revealed in a letter sent yesterday to Republicans in Congress that experiments it funded through a U.S.-based nonprofit in 2018 and 2019 at the Wuhan Institute of Virology (WIV) in China had the “unexpected result” of creating a coronavirus that was more infectious in mice.

NIH says the organization holding the parent grant, the EcoHealth Alliance, failed to immediately report this result to the agency, as required. A newly released progress report on that grant also shows that EcoHealth and WIV conducted experiments changing the virus that causes Middle East respiratory syndrome (MERS), which is raising additional questions.
