Cool. Love it. Cowpox is the paper to Smallpox's rock. Knowledge spread by the book in 1798. Old wives tales in print saved the day

In 1798, after testing his discovery on more people, Jenner published his findings in a booklet,
An Inquiry into the Causes and Effects of variolae vaccinae, a Disease Discovered in some of the Western Counties of England, Particularly in Gloucestershire, and Known by the Name of Cowpox. In it he concluded that “Cowpox protects the human constitution from the infection of smallpox.”
Jenner’s book was soon translated into several languages, and physicians began performing vaccination throughout Europe.

I did a google search and found a claim that the Chinese practiced a form of Smallpox inoculation even earlier in the 1500s.
"In The Life and Death of Smallpox, note that in the late 1600s Emperor K'ang Hsi, who had survived smallpox as a child, had his children inoculated. That method involved grinding up smallpox scabs and blowing the matter into nostril. Inoculation may also have been practiced by scratching matter from a smallpox sore into the skin. It is difficult to pinpoint when the practice began, as some sources claim dates as early as 200 BCE."
