A few days after a Pennsylvania lab was closed because an employee found plates labeled “smallpox” in the refrigerator, the CDC says there is no reason to fear the spread of the virus. Late Thursday night, authorities announced that the bottles were free of variola virus. Instead, he had a similar but more common virus, which is used in making smallpox vaccines.

Earlier this week, the Centers for Disease Control and Prevention revealed that a lab worker unveiled cool dishes while washing in the refrigerator at the Merck, Pennsylvania vaccine research institute working with the CDC. There were 15 plates, five labeled “smallpox” and 10 labeled “vaccinia,” The New York Times reports, referring to a local elder. The bowls were moved to another location for testing Wednesday. And it was now discovered that the plates of “smallpox” were also infected with the vaccine.

“There is no evidence that the shells contain the variola virus, which causes smallpox,” the CDC said in a statement sent to the New York Times on Thursday.

Vaccinia is a viral infection an interesting history. Edward Jenner developed the first vaccine against smallpox in the late 19th century, using what he believed was a smallpox virus, a cousin of smallpox that caused very few infections in humans (the virus killed 30% or more of the population). However, whether the original vaccine had cowpox is not known, because the virus used in vaccines that became the basis of most vaccines disappeared. vaccinia, which is very similar to cattle. These differences have not been known for a long time, and no one is sure if the vaccine came from the original lab cowpox, from another virus called the virus. kavalo, or as a hybrid of several pox viruses. Its exact origin is still a mystery, and the vaccine is not thought to exist in the wild. After the vaccine was confirmed to be a well-known virus, the vaccine was named based on the technology with which it was identified.

In any case, vaccination is a vaccine Even more dangerous than taking smallpox, although the shooting often endshas a skin lesion on the recording site. The risk of anyone being identified by the contents of the soft drinks was minimal, the CDC said, as they were left unattended and the lab worker said he was wearing a face mask and gloves at the time.

More than five years ago, laboratory staff at the National Institutes of Health said come on such a collection of smallpox samples, some of which had a viral infection. And while there are only two official sites in the US and Russia where smallpox can be stored for study, scientists doubt that there are any hidden stocks. However, at present there is no risk of developing smallpox.
