Smallpox
Smallpox is believed to have been around since ancient times, so it is difficult to pinpoint exactly where it was first discovered. However, the earliest recorded outbreaks of smallpox date as far back as ancient Egypt, India, and China. The first vaccine for smallpox was developed by Edward Jenner in the late 18th century.
Edward Jenner discovered that farmers who had caught cowpox did not suffer from smallpox. He then started injecting people with small doses of cowpox and he observed that they did not catch smallpox. He had created a vaccination for smallpox. :D
The first known cases of smallpox go back to 1350 BC and the disease has been known for a very long time. Dr. Campbell identified how smallpox is spread. Edward Jenner is credited with developing the smallpox vaccine in 1796.
The microorganism responsible for smallpox is the variola virus. It is a member of the Orthopoxvirus genus. Smallpox is a highly contagious and potentially deadly disease that has been eradicated through global vaccination efforts.
On May 18th, 1749, Edward Jenner was born. He was an English Doctor Who discovered a cure for people with something called "smallpox". It's very rare, and he took pus from a cowpox pustule and insert it into the arm of a boy who had smallpox. Weird enough, it actually saved this boy from smallpox.
