Smallpox was once a common epidemic disease that killed, blinded or disfigured its victims. In the eighteenth century its impact was reduced in Europe by a Chinese practice called variolation, the injection of smallpox fluid from an infected human being into a healthy human. In 1798 Edward Jenner proposed a modification of variolation called vaccination, which involved the injection of fluid from an infected cow into human beings.
