The Royal Philanthropic Vaccine Expedition (Spanish: Real Expediciσn Filantrσpica de la Vacuna), commonly referred to as the Balmis Expedition, was a Spanish healthcare mission that lasted from 1803 to 1806, led by Dr Francisco Javier de Balmis, which vaccinated hundreds of thousands against smallpox in Spanish America, the Philippines, and China. The vaccine was transported through children: orphaned boys who sailed with the expedition and, for part of the journey, three enslaved girls from Cuba.(Submitted on March 5, 2026.)
The mission took the vaccine to the Canary Islands, Puerto Rico, Venezuela, Colombia, Ecuador, Peru, Mexico, the Philippines and China. The ship carried also scientific instruments and translations of the Historical and Practical Treatise on the Vaccine by Moreau de Sarthe to be distributed to the local vaccine commissions to be founded.
In the Philippines, they received help from the Catholic church, which was initially reluctant until Governor-General Rafael Aguilar made an example by vaccinating his five children.
The Balmis expedition can be considered the first international healthcare expedition in history. Jenner himself wrote, "I don't imagine the annals of history furnish an example of philanthropy so noble, so extensive as this."
