Shi Zhengli also performed gain of function research on bat SARS and SARS-like viruses to add to them the ability to use ACE2 receptors to enter human cells - the mechanism SARS2 uses to enter human cells. She also use HIV as a source of parts for such gain of function research with these viruses.

She is most of the reason the Wuhan Institute of Virology is unable to shake accusations it is the source of the current pandemic pathogen, because her research adding functions to these bat virii looks exactly like how to make the current pathogen killing people all over the world.

Thanks!
