<P> Smallpox vaccine , the first successful vaccine to be developed , was introduced by Edward Jenner in 1796 . He followed up his observation that milkmaids who had previously caught cowpox did not later catch smallpox by showing that inoculated cowpox protected against inoculated smallpox . The word `` vaccine '' is derived from Variolae vaccinae ( i.e. smallpox of the cow ) , the term devised by Jenner to denote cowpox and used in the long title of his An enquiry into the causes and effects of Variolae vaccinae , known by the name of cow pox . Vaccination , the term which soon replaced cowpox inoculation and vaccine inoculation , was first used in print by Jenner 's friend , Richard Dunning in 1800 . Initially , the terms vaccine / vaccination referred only to smallpox , but in 1881 Louis Pasteur proposed that to honour Jenner the terms be widened to cover the new protective inoculations being introduced . </P>
