Edward Jenner. He was testing cow pox (nonfatal) and small pox (fatal). He noticed that whoever had one never had the other, and some had neither. He put both into a boy, and then the boy was not affected by the small pox. Vaccine comes from vaccinia (lation) for "of the cow" because the cow pox stopped the small pox from working.
