He was variolated when he was a child

Humanity was wiped out by smallpox for many ages. Thanks to Edward Jenner's outstanding work and subsequent advancements resulting from his endeavors, we do not have to worry about it in the present era. One of the most interesting facts about Edward Jenner is that he was variolated as a child. In the 18th century, smallpox was widely distributed and occasionally had unusual intensity outbreaks that had a very high mortality rate. The illness, which was a major cause of death at the time, had little regard for social standing, and those who survived frequently suffered from disfigurement.

Variolation was the standard treatment at the time for smallpox (Variola). Mild smallpox matter was injected into a person to cause variation. Smallpox would then affect the patient less severely than if it had come to him spontaneously. If the symptoms disappeared after a few weeks, the patient recovered and grew immune to the illness. Although usually effective, this approach was not infallible and several people died as a result. Although he had a high fever and had been variolated as a child, Edward Jenner managed to survive. On the other hand, this had a long-lasting impact on his general health.
