Philadelphia — Federal health authorities on Wednesday
confirmed the discovery of some frozen vials labeled "Smallpox" in a
freezer at a facility in Pennsylvania that conducts vaccine research. ...
The CDC would not confirm where in Pennsylvania the vials were found. ...
There are two sites designated by the World Health Organization where stocks of variola virus are stored and used for research: the CDC facility in Atlanta and a center in Russia. ...
In July 2014, officials said a government scientist cleaning out an old storage room at a Bethesda, Maryland, research center found six decades-old glass vials containing freeze-dried smallpox samples packed away and forgotten in a cardboard box. Officials called it the first discovery of unaccounted-for smallpox in the country.
