The Inoculation Experiment (1721)
During the 1721 smallpox epidemic, Onesimus — an African man enslaved by Cotton Mather — described the inoculation practiced in West Africa. Dr. Zabdiel Boylston acted on it over violent opposition: the first inoculation campaign in the Western world, and it worked.
Boston’s first public-health revolution came from an enslaved African’s knowledge — three centuries before the city helped design the COVID vaccines.
