Edward Jenner was an English country physician who was convinced that he had found a way to prevent smallpox, one of the world’s deadliest diseases in 1796.
He experimented with a child to see if he could give him immunity to smallpox. He succeeded and the kid never got smallpox as cowpox had given him immunity. Jenner called his discovery vaccine.
