Human: Where did the Smallpox vaccine originate? Assistant: 
The Smallpox vaccine was developed by Edward Jenner in 1796. Jenner was a British doctor who noticed that milkmaids who had been exposed to cowpox did not get smallpox. He then developed a vaccine by inoculating people with cowpox, which is a mild form of the disease. The vaccine was very effective, and it was used to protect people from smallpox until the 1960s.
