Edward Jenner (date unknown)
^BEdward Jenner.^b Historical portrait of British physician and naturalist Edward Jenner (1749- 1823). Jenner is famed for developing a vaccine for the often fatal viral infection, 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 immunising process was named vaccination after the cowpox virus (^Ivaccinia^i), and was made compulsory in Britain in 1853. Smallpox was declared extinct outside laboratories in 1980.
