Isabel Zendal Gómez (born 1773) was a Spanish nurse from Galicia who took part in the Balmis Expedition (1803-1806, Real Expedición Filantrópica de la Vacuna), which took smallpox vaccination to South America and Asia.[1][2]
She had previously been the supervisor or "rectoress" of an orphanage in A Coruña, and her role on the expedition was to take care of the group of 22, later 26, small orphan boys who carried the virus from which the vaccine was prepared.[2]
The three-year expedition aimed to vaccinate millions of people against smallpox, and had the support of king Charles IV of Spain whose daughter had died of the disease.
