Today in 1799, Edward Jenner introduced smallpox vaccine, which eventually led to wiping out this deadly disease. Jenner was an English physician and scientist who was the pioneer of smallpox vaccine, the world’s first vaccine. The terms “vaccine” and “vaccination” are derived from Variolae vaccinae (smallpox of the cow), the term devised by Jenner to denote cowpox. He used it in 1798 when he described the protective effect of cowpox against smallpox.
Jenner is often called “the father of immunology,” and his work is said to have saved more lives than the work of any other human. In 2002, Jenner was named in the BBC’s list of the 100 Greatest Britons. (from Wikipedia)
