Edward Jenner

In the 18th century, smallpox was one of the epidemic diseases with the highest mortality rate.The only known treatment at the time was of a preventive nature, and consisted of inoculating a healthy subject with infected matter from a patient suffering from a mild attack of smallpox.This principle was based on empirical evidence that a subject who had overcome the disease did not contract it again.However, the inoculated person did not always develop a mild version of the disease and died often; furthermore, it could act as a source of infection for those around it.
