Edward Jenner was an English country doctor, practicing in Berkeley, Gloucestershire?
He was a disciple of [John Hunter]?.
It was vaccination that made him a
place in history. Not only the history of medicine but undisputably in the
history of mankind?.
By Jenner's time, the process of smallpox inoculation had become commonplace in England, but had a major disadvantage: until the infection from inoculation had run its course, the subject was infected, and infectious, with actual smallpox, and a risk to anyone around them who was not already immune.
There was a local folk tradition amongst those who milked cows, that an infection with the so-called `cow-pox' protected one from being infected by smallpox. Cowpox was utterly harmless (compared to smallpox) and Jenner realised that if the folk tradition were true, it offered considerable advantages over the use of smallpox in inoculation. He tested cowpox, infecting a boy named James Phipps in the same manner as used in smallpox inoculation, but using material from a cowpox pustule. The boy contracted cowpox, and recovered with no harm. Jenner then applied the standard smallpox inoculation; the boy was completely unaffected, showing that cowpox had made him immune to smallpox.
Jenner called his method `vaccination', as the original infective material came from a cow, His work was published in 1798.
Jenner realised the long-term implications of vaccination, and looked foward to the day when smallpox would no longer be a threat anywhere on earth; his dream eventually reached fruition with the global eradication of smallpox in the late 1970s.
James Phipps' house in Berkeley is now the Jenner Museum
