title: Smallpox vaccination in the early 19th century using live carriers: the travels of Francisco Xavier de Balmis.
abstract: Realizing that the Spanish colonies were being devastated by epidemics of smallpox resulting in thousands of deaths, Charles IV, King of Spain, sent one of his court's physicians to apply the recently discovered vaccine. Without refrigeration, the vaccine was passed from one child to another (boys taken out of orphanages). Francisco Xavier de Balmis and a team that included three assistants, two surgeons, and three nurses sailed from Spain on November 30. 1803. They vaccinated more than 100,000 people from the Caribbean Islands and South, Central, and North America, reaching up to San Antonio, Texas, and then traveled to the Philippines, Macao, Canton, and Santa Elena Island, landing back in Cadiz on September 7, 1806. During his journey, Balmis instructed local physicians on how to prepare, preserve, and apply the vaccine, while collecting rare biologic specimens. On the 200th anniversary of their sailing, recognition is given to this group for conducting what was the first global vaccination campaign that reached Texas and California.
