I'm trying to figure out how long he worked at the lab. It seems like it was between 2014 and 2016. But they also say he worked at "New York-based" EcoHealth -- and then later that that nonprofit "helped the Wuhan lab put together" some research. Would the headline feel different if it read, "Covid was man-made virus, says scientist who worked briefly at Wuhan lab sometime between 2014 and 2016."
