The smallpox vaccine is used to prevent smallpox infection caused by the variola virus. [10] It is the first vaccine to have been developed against a contagious disease. In 1796, British physician Edward Jenner demonstrated that an infection with the relatively mild cowpox virus conferred immunity against the deadly smallpox virus.
In 1799, the physician Valentine Seaman administered the first smallpox vaccine in the United States.

Smallpox was an infectious disease caused by variola virus (often called smallpox virus), which belongs to the genus Orthopoxvirus.

Most of the confusion here stems from the fact that the virus inside smallpox vaccines isn’t found in nature. Vaccinia virus seems to only exist in laboratories, not in any biological hosts.
It began working on its smallpox vaccine, similar to the one used for mpox, back in 2003 with the U.S. government. Bavarian Nordic has been instrumental in developing and supplying vaccines ...
The Americas and Australia remained free of measles and smallpox until the arrival of European colonists between the 15th and 18th centuries.
