14h 12min, may 14, 1796 y - Edward Jenner Presents the First Smallpox Vaccine
Description:
Englishman Edward Jenner took fluid from a cowpox blister and scratched it into the skin of James Phipps, an eight-year-old boy. A single blister rose up on the spot, but James soon recovered. On July 1, Jenner inoculated the boy again, this time with smallpox matter, and no disease developed. The vaccine was a success.
