However, we do not hear much about it any more. Why? Because it is no longer around in nature. This happened mainly because of the work of Edward Jenner(1749—1823), an English doctor and scientist. Jenner did not have an easy childhood. His parents died when he was young, and his elder brother raised him. It was difficult for him to do well in school, but he had a passion for nature. At 13, he became an apprentice to a doctor for eight years. It was hard for doctors to be well-respected at that time because modern medicine had not fully developed.When Jenner was 21, he studied at a hospital in London. Smallpox disappeared because of Jenner’s work Jenner’s hard childhood and early medical training Careful reading After he finished his studies, Jenner went back to his home in the countryside because he liked it more. There, he became a family doctor and people started to hear about his good work. In his free time, he continued to do research and study nature. It was while working as a doctor that Jenner discovered that milkmaids-women who milk cows-rarely got smallpox. They often got cowpox, a disease like smallpox, but these milkmaids did not get very sick and they did not die. He wondered: Do milkmaids get protected from smallpox just because they often get cowpox? Jenner worked as a country doctor and kept researching Jenner found milkmaids seldom caught smallpox To test this, Jenner came up with the idea of first giving some people cowpox, then giving them smallpox. These people did not get the smallpox! After many other tests, he realized that cowpox could actually be used to protect people from getting smallpox. Jenner invented a new word to describe what he had created: “vaccine”. The word comes from the Latin word for “cow”. It is wonderful that, because of Jenner’s work, smallpox is not around any more and people no longer die from it. His pioneering research has been used to create vaccines for other diseases.
