Santa Cruz de Tenerife was the first port to which the Balmis Expedition arrived in 1803, the great international sanitary operation that Spain promoted to bring the smallpox vaccine to the Spanish Empire. It spent a month in the capital city, vaccinating thousands of people.

What was that expedition? It was the first international operation of a sanitary and humanitarian nature, proposed to King Carlos IV by the Spanish doctor and military surgeon Francisco Javier de Balmis y Berenguer in order to bring the smallpox vaccine to the Spanish Empire to save hundreds of thousands of lives, especially children. It would be Carlos IV himself who would pay for it.
In order for the vaccine to withstand the long journey, Balmis took a group of orphaned children under the age of 10 as a natural reservoir, as they were inoculated with the vaccine, in order to extract the fluid from the pustules that formed (in what was called the "serial method "). In this way, thousands of people residing in the different territories of the Spanish Empire could be inoculated.

The first port that the aforementioned expedition reached was that of Santa Cruz de Tenerife, where it spent a month vaccinating thousands of people and from where it left for America on January 6, 1804.
Venezuela, Colombia, Ecuador, Peru, all the territory known at that time as New Spain that included Mexico, California and Texas; the Philippines, China and the island of Saint Helena (although she was British), were the main regions where the procedure would be carried out.
The expedition carried 2,000 copies of the "Practical and Historical Vaccine Treaty" by the French physician and anatomist Moreau de Sarthe to distribute to the different vaccination commissions that were created in each place, so that they could learn and continue with the vaccination process.
The Balmis expedition was, without a doubt, the first and one of the greatest milestones in history of preventive and social medicine and public health that any country has ever carried out, saving the lives of thousands of people who, without it, would have died, although, even today it is unknown by many people in the country.
