Vaccinia
Vaccinia
Vaccinia (pronunciation: /vækˈsɪniə/) is a genus of viruses in the family Poxviridae, and is the virus used in the smallpox vaccine. The term is derived from the Latin vaccinus, meaning "of or from the cow", as the smallpox vaccine was historically derived from cowpox.
Etymology
The term "vaccinia" is derived from the Latin vaccinus, meaning "of or from the cow". This is in reference to the historical use of cowpox to create the smallpox vaccine. The term was first used in this context by Edward Jenner in 1796, who discovered that milkmaids who had contracted cowpox did not catch smallpox.
