Dr. Francis Collins appeared to acknowledge this week that the U.S. agency he heads funded gain-of-function experiments in Wuhan, China, which runs counter to claims he and a subordinate made earlier this year.
The National Institutes of Health (NIH), the agency Collins directs, revealed last week that money it gave to EcoHealth Alliance supported risky experiments at the Wuhan Institute of Virology in China that some experts said met the definition of gain-of-function.
