balmis expedition

The operation officially named Real Expedición Filantrópica de la Vacuna, the Spanish healthcare mission under the leadership of Doctor Francisco Javier de Balmis set sail on the María Pita from a port in Galicia on this day in 1803 and would vaccinate, using the technique developed by Edward Jenner, untold millions against smallpox, calling in the Canary Islands, Colombia, Ecuador, Peru, Mexico, China and the Philippines, even offering surplus to the colony at Saint Helena on the return route, despite animosities between Spain and Britain at the time. Undertaken to make amends for the Old World diseases that ravaged North and South America and to attempt to wipe out the contagion that proved fatal for nearly half a million individuals annually in Europe only, the complement and crew included twenty-two orphaned boys designated as successive carriers of the cowpox virus (there being no refrigeration or other means to isolate and transport the vaccine), which would help recipients acquire immunity to the deadlier version.
