What is smallpox?
Smallpox was thought to originate in Africa and spread to India and China. The first recorded epidemic of smallpox was in 1350 B.C., and the first reports of smallpox in Europe occurred between the 5th and 7th century. It was not until the 17th and 18th century that epidemics were noted in the North American colonies.
Then Edward Jennings found that cowpox was the natural vaccine for smallpox, but you had to contract it and let it go away before your body finished building up the immunity to smallpox, or you could get smallpox as well as cowpox.
Smallpox is a contagious and fatal disease. There is no treatment for smallpox so you must get a vaccination to prevent it.
