Immunizations were developed by Edward Jenner in 1796, although it was first performed by a cow farmer on his family twenty years earlier. Jenner noticed that milkmaids were less likely to catch smallpox than the general population. He then noticed that milkmaids who had previously contracted cow pox did not catch small pox. He theorized that if somebody had had cow pox then they were immune to small pox. He tested this by giving cow pox to a young boy then injecting him with small pox. Although the boy experienced a small amount of illness when given the cow pox, he did not experience any nasty effects from the small pox, a far more dangerous disease. And hence vaccines were born.
