On July 5, 1886, Harold Newell began a series of ten inoculations after being bitten by a rabid dog, just one year after Joseph Meister received the world’s first dose from Pasteur.

Newell received the first dose of Pasteur’s rabies vaccine in the United States, marking a critical milestone in American medical history following Louis Pasteur’s 1885 success in France.

The treatment was supervised by Dr. Valentine Mott at the American Pasteur Institute, located in the Carnegie Laboratory in New York City. The vaccine was produced using dried, attenuated spinal cords of rabies-infected rabbits.
