Medical Interventions- Dr. Edward Jenner

During the 18th centry there was a huge occurance of small pox around the united states. 45 million people were victims of small pox. Dr. Edward Jenner noticed that the only people that were not getting this disease were cow maids, and that they had already contracted the disease cow pox. So he did a little research and some tests. He thought that the puss from a sore of the disease cow pox could possibly kill off the small pox resulting in curing the disease. So to test this theory, he injected a small healthy boy with the puss of the cow pox. He noticed that the boy had a small fever but somewhat recovered. After that he had taken the small pox virus and had injected it into the bloodstream of the boy. A few days later the boy appeared to be normal. This was a breakthrough in the medical community. This was when the term "vaccination" was created.
