Protection against smallpox by inoculation with the cowpox virus. Edward Jenner (1749-1823), British physician and naturalist, developed a vaccine for the often fatal viral infection of smallpox. He investigated folk tales about the immunity of cowpox victims to smallpox. In 1796 he used a thorn to inoculate a healthy boy with fluid from a cowpox blister on a dairy maid's finger. Six weeks later he inoculated the boy with smallpox, and the boy did not develop the disease. The immunizing process was named vaccination after the cowpox virus (vaccinia), and was made compulsory in Britain in 1853. Smallpox was declared extinct outside laboratories in 1980.
