Smallpox+vaccine

** By Scarlett ** A man named Edward Jenner discovered the small pox vaccine in 1796 and his work was published in 1798. He worked in a rural community where most of his patients were farmers or worked on farms with the cattle. He worked out that cowpox was a milder version of small pox and people who caught cowpox didn’t catch Small pox. One day a young milkmaid called Sarah Nelmes came to him with blisters all over her hand. Jenner told her she must have caught cowpox from a cow. Jenner saw his chance and extracted some pus from her blisters. Then he deliberately infected a small, eight year old boy called James Phillips with cowpox. A few weeks later when James had recovered Jenner exposed him to small pox and James did not get ill. Jenner tried this on many other children (including his own son) and the results were the same. Jenner concluded that they were immunized against smallpox. The small pox vaccine is not really used anymore because smallpox is now an extremely rare disease. Smallpox outbreaks have occurred from time to time for thousands of years. The last case was in 1977.
