Weren’t the remaining stocks of the smallpox virus destroyed after smallpox was eradicated?
When smallpox was officially certified as eradicated, in December 1979, an agreement was reached under which all remaining stocks of the virus would either be destroyed or passed to one of two secure laboratories – one in the United States and one in the Russian Federation. That process was completed in the early 1980s and since then no other laboratory has officially had access to the virus which causes smallpox.
