It doesn't. It is the only human infectious diseas known to have been completely eradicated by mankind. The last known cases were in 1978.
Edward Jenner was a medical doctor, surgeon and scientist. He is also called the "father of immunology" for his work in producing a smallpox vaccine. The smallpox vaccine was actually a cowpox variation but it did provide protection against smallpox.
Smallpox contains DNASmallpox is a virus, and therefore, can only have RNA or DNA. In the case of smallpox, it contains DNA. Viruses require a host to supply them with either RNA or DNA in order that more virus entities can be made.DNA
His discovery led to the eradication of smallpox around the world.
No. After you get a disease like smallpox, your body is able to develop permanent defenses against it. This makes you "Immune" to the disease. This is the principle on which vaccines work.
Because James Phipps had never had Smallpox and Jenner needed somebody who was not immune to smallpox or else this experiment would not work.
its smallpox
no it is rare to get smallpox. although it is still possible to get smallpox
Edward Jenner discovered the smallpox vaccine in 1796 when he observed that milkmaids who had contracted cowpox, a less severe disease, seemed immune to smallpox. He hypothesized that exposure to cowpox could protect against smallpox. To test his theory, he inoculated a boy named James Phipps with material taken from a cowpox sore, and later exposed him to smallpox, finding that he did not become ill. This pioneering work laid the foundation for the development of vaccines and the eventual eradication of smallpox.
The cure for smallpox is cowpox. Cowpox is a mild version of smallpox and is usually not fatal. The smallpox vaccine contains cowpox.
Edward Jenner made the link between cowpox and smallpox through his observation that milkmaids who contracted cowpox, a disease affecting cattle, seemed to be immune to smallpox. In 1796, he tested this hypothesis by inoculating a boy with cowpox pus and later exposing him to smallpox; the boy did not develop the disease. This experiment demonstrated that cowpox provided protection against smallpox, leading to the development of the first vaccine. Jenner's work laid the foundation for immunology and the eventual eradication of smallpox.
An example sentence with the word "smallpox" is: My sister was diagnosed with smallpox when she was three.
Edward Jenner is credited with introducing the smallpox vaccine in 1796. He discovered that milkmaids who had contracted cowpox, a less severe disease, appeared to be immune to smallpox. Jenner tested this hypothesis by inoculating a young boy with cowpox, and later exposing him to smallpox, which confirmed the vaccine's effectiveness. This groundbreaking work laid the foundation for modern immunology and vaccination practices.
