Edward Jenner's Theory Of Smallpox

The first time Edward Jenner heard about smallpox was when he was a young practitioner. He heard a woman that said she was not going to get smallpox because she already had cowpox. At that time it did not make sense, but later on did. After he became a physician, he founded that smallpox and cowpox were similar because they were diseases derivatives from the same “family.” Time passed and in one of his consultations, he went out on the field and during this transition Mr. Jenner observed that some local people did get infected with smallpox, even though they were in contact with people who had it. Furthermore, it is here where Jenner started making observation in the people who acquire cowpox because these people did not get sick of smallpox.
He meets a woman named Sarah Nelmes who had a fresh case of cowpox. She acceded to provide a sample of it. Such sample was going to be tested in a healthy person. In this first experiment, the patient was a kid of eight years old named James Phipps. He was the gardener's son of Sarah Nelmes. During the first exposition, the kid presented fever and some other symptoms. After several days, the kid was feeling better and healthy. Then, after almost two months the second exposition was going to be the real virus, smallpox. Fortunately, James Phipps did not get sick or developed symptoms of smallpox. Therefore, Jenner’s theory was successfully proven. Subsequently, Edward Jenner took as an example Phipps Case to continue experimenting with his
Before the method to prevent smallpox of Edward Jenner was discovered, people used variolation because it was the only procedure that existed at that time, which could bring them a higher chance to survive against the disease. After testing in many people his theory about if a person acquires cowpox thus ended up being immune to smallpox, he was able to prove it. This new method that Edward Jenner found is known as vaccination. After the vaccination was discovered, variolation was discarded because it was no longer considered safe. Although Edward Jenner had some complications, thanks to vaccination he was able to prevent more people from getting sick and dying from this disease. Additionally, after he helped to prevent this epidemic, Mr. Jenner was able to prevent the expansion of smallpox to other places. Furthermore, after Edward Jenner’s death people in the field of the medicine continued to study his investigation and thanks to his discoveries people were able to improve vaccination. Time after, this new improve vaccination helped to eradicate smallpox in the United States and worldwide. For all these reasons, Edward Jenner was an important character in the United States and in the entire
