This is what the Spanish Ministry of Defense calls the military operation against the coronavirus pandemic, in memory of the "Balmis Expedition" that spread the smallpox vaccine throughout America and Asia in the early 19th century. It was directed by the acannian botanist and surgeon Francisco Javier de Balmis y Berenguer who had previously worked in Havana and Mexico City. The 2016 TVE film "22 Angels", in memory of the children who carried the vaccine, reminds us of these facts.
