Edward Jenner's Work on antibiotics

In the eighteenth century over forty million people died of small pox. It was noticed that the people who worked in the dairy business were getting a similiar strand called cow pox and were immune to small pox. Mr. Jenner, a doctor, went to the village were it was becoming more noticed that the dairymen and milk maids werent getting sick and extracted some puss from one of the sores on their skin. He then studied the two diseases and decided to do a study. Jenner's innoculated an eight year old bold who was in perfect health with the cow pox puss. He left to conitinue his research elsewhere but returned 6 weeks later. When he came back he again innoculated the then sick boy with small pox. A few days later he returned to find the boy alive and well, and most importantly uneffected by the small pox.
