Officially, the smallpox virus exists in only two repositories: in freezers in a building called Corpus 6 at Vector in Siberia, and in a freezer in a building called the Maximum Containment Laboratory at the Centers for Disease Control in Atlanta. But, as Peter Jahrling often says, “If you believe smallpox is sitting in only two freezers, I have a bridge for you to buy. The genie is out of the lamp.”
