Louis Pasteur successfully tests his vaccine against rabies on Joseph Meister, a boy who was bitten by a rabid dog #OTD in 1885.
Later, people, including 4 children from the United States, went to Pasteur's laboratory to be inoculated. In 1886, he treated 350 people, of which only 1 developed rabies. The treatment's success laid the foundations for the manufacture of many other vaccines. The 1st of the Pasteur Institutes was also built on the basis of this achievement. via @wikipedia
