Vials of deadly virus accidentally discovered at Pennsylvania research facility while cleaning freezer: CDC
Fox News
Several frozen vials labeled "smallpox" were incidentally discovered by a laboratory worker while cleaning out a freezer in a facility that conducts vaccine research in Pennsylvania
There were reportedly a total of 15 questionable vials, according to the unclassified "For Official Use Only" alert, a copy of which was obtained by Yahoo News. Five of the vials were labeled "smallpox" and 10 were labeled "vaccinia." The vials were secured immediately.CDC's website says smallpox, a disease caused by the variola virus, was eradicated thanks to the success of vaccination and no cases of naturally occurring smallpox have happened since 1977. The last natural outbreak of smallpox in the United States occurred in 1949.The virus is considered so deadly that only two labs in the world are authorized to store samples of it, one in Russia and the other at the CDC in Atlanta.
Scientists have debated for years whether or not to destroy the remaining samples. Those in favor of keeping them have argued they are needed to develop new vaccines in response to a new outbreak.
The majority of Americans are not vaccinated against smallpox, and those who were vaccinated would likely now have waning immunity.The CDC will arrive on site Wednesday to take custody of the vials and transport them to another facility for testing, the alert notes, Yahoo News reports.Merck did not immediately respond to a request for comment.
