Hi Brian, A friend was the second in command at the Soviet Biowarfare site, Vector. So I am very aware of what has been done, both publically and in the classified world. Those interested in the subject should read a book by his direct boss:https://www.amazon.com/Biohazard-Chilling-Largest-Biological-World-Told/dp/0385334966

There is a long list of serious lab leaks of biologically dangerous material both here and in the Soviet Union. But as a molecular biologist I never imagined that an engineered coronavirus could or would cause such havoc. By the way, the Chinese have abandoned the story that it was a zootic transfer and they now blame Fort Detrick.
