Vaccination

In 1796, English physician Edward Jenner administered the first vaccination against smallpox to an eight-year-old boy. Jenner innoculated an 8-year-old boy, James Phipps, with material from the sores of dairymaid Sarah Nelmes who had a mild case of cowpox. A few weeks later, on 1 Jul, he subsequently tested the boy's resistance to smallpox, by inoculating Phipps with smallpox virus. Fortunately, the immunization had been successful. This tested a conventional wisdom he had heard that those who had survived cowpox seemed to be immune to the deadly smallpox disease. By 1798 he had 23 cases, which he recorded in An Inquiry into the Causes and Effects of the Variolae Vaccinae. Jenner's work was rapidly taken up in Europe and America.«
