1932 – A vaccine for yellow fever is announced for use on humans. In 1927, scientists had isolated the yellow fever virus in West Africa. Following this, vaccines were developed in the 1930s. The vaccine 17D was developed by the South African microbiologist Max Theiler at the Rockefeller Institute in New York City. This vaccine was widely used by the U.S. Army during World War II.
