Vaccines and the end of smallpox
Smallpox killed hundreds of millions of people. In 1721 inoculation was brought to Britain from Turkey, and to Boston from West Africa; Edward Jenner showed in 1796 that cowpox could protect against it; and in 1980 the World Health Organization declared smallpox gone from the Earth.
