Edward Jenner the father of Immunology

Edward Jenner, known as the father of Immunology. He was the first to discover a vaccine for smallpox. Observation that young women who were exposed to cowpox did not catch smallpox Note and study Miss Sarah Niles, who had previously contracted smallpox and was later found to be immune to smallpox because she contracted cowpox fever, and those who contracted cowpox had blisters on their hands. Jenner concluded that those blisters, in a way, were protecting them. For example, he took a sample of a cowpox patient and injected it into another person, so he concluded that he would generate future immunity against smallpox. In fact, this disease is similar to it, but it is less dangerous. Jenner was able to prevent people from catching smallpox. Cowpox is a mild disease that causes several ulcers on the hands, and the risks are low. For example, he took a sample of the ulcers on the hand of Sarah Nalms, who had cowpox, cut a wound in the arm of James Phipps, a healthy boy, and inserted the ulcerated substance he had taken from Sarah's sores. 48 days later. Jenner inserted smallpox into the boy's arm, and this substance It is usually fatal, but it did not affect the boy because he had been fed cowpox, and thus Jenner's experiment worked. Finally, the experiment worked, and that was the first time the vaccination was done, and it’s saved many people lives
