Born on May 17, 1749 in Berkeley , England. He practiced under many
skilled doctors and then set up his own medical business. In those days
small pox was a fatal disease and many of the affected died and the
survivors were disfigured. Jenner observed that the persons affected with
cowpox never contracted smallpox. Thus he developed the vaccine against
small pox from the wound of a cowpox infected lady. He was awarded 30000
pounds by the British Government for his discoveries. Now vaccination is
used all over the world.. Jenner died on 1823.
