It’s not a weapon. I figure somebody was fiddling with it in the lab, and then he or somebody else spilled it. It could have been in study for a vaccine, as some people have speculated.
How do you explain the antibodies to a bat coronavirus found in Chinese villagers (not near any lab), study published 3 years ago?
I’m willing to bet what’s left of my retirement acct. that if virus signatures (or antibodies) would survive that long, one could dig up dead Chinese villagers from any time period you please, and some would have similar evidence.
