Wikipedia definition
2. Smallpox vaccineThe smallpox vaccine was the first successful vaccine to be developed. The process of vaccination was first publicised by Edward Jenner in 1796, who acted upon his observation that milkmaids who caught the cowpox virus did not catch smallpox. Prior to widespread vaccination, mortality rates in individuals with smallpox were high—up to 35% in some cases.
