There is a history of smallpox inoculation that goes back as far as 1000 AD in China, Africa, and Turkey. However, the person credited with creating the first vaccine is Edward Jenner, an English scientist who pioneered one for smallpox in 1796. His breakthrough came from taking pus from a blister of someone infected with cowpox and using it to inoculate another person, thus preventing smallpox in that person. He developed this treatment after hypothesizing that dairy workers were rarely, if ever, infected with the deadly smallpox virus because most of them were already infected with cowpox, which has a very mild effect on humans.
