Smallpox. Louis Pasteur discovered the vaccine for small pox, using the cow pox organisms.
Homeotherapy is using a similar disease to prevent a disease like cowpox was used to cure smallpox.
The smallpox vaccine comes from cows. Most diseases you a weakened form of the disease. However the smallpox vaccine is brought from cowpox. (closely related to smallpox but not as dangerous). You cannot get this vaccine anymore and if you did it would result in a bad reaction.
Cowpox was probably known as long as people have had domesticated cattle. However the observation was not made until the late 1700s that infection with cowpox from working with cattle infected with cowpox prevented infection with smallpox. This observation eventually led to the introduction of safe vaccination (using cowpox pus taken from cattle) to replace often hazardous variolation (using smallpox pus taken from humans).
Edward Jenner, an English physician, is credited with inventing the first cowpox vaccine during the Enlightenment period. He developed the smallpox vaccine using cowpox virus after observing that milkmaids who had contracted cowpox did not get smallpox. His discovery laid the foundation for modern vaccination practices.
When Edward Jenner developed the first vaccine in 1796, he observed that milkmaids who had contracted cowpox, a disease similar to smallpox, seemed to be immune to smallpox. This led him to hypothesize that exposure to cowpox could provide protection against smallpox. Jenner tested this by inoculating a young boy with cowpox material, which ultimately demonstrated the principle of vaccination and laid the groundwork for immunology. His work significantly contributed to the eventual eradication of smallpox.
Jenner's method of using cowpox infection to confer immunity to smallpox was superior to earlier methods because it carried a significantly lowered risk of serious disease. The earlier method of using material from lesions of smallpox victims conferred immunity but at the risk of acquiring the potentially lethal disease.
"When he was young he was given smallpox on purpose. It was hoped that, because he was so young and healthy, he would survive and so live to tell the tale if he caught smallpox when he was older."
Edward Jenner is generally credited with inventing the first vaccine against smallpox in 1796 using material from the blisters of cowpox, however the first paper published that mentioned the principle of using cowpox to prevent smallpox was filed by Dr Fewster in 1765, but he never pursued the idea.
Edward Jenner worked as a health practitioner and local surgeon in Berkeley, his hometown. He started his own practice in his hometown. He noted that cowpox patients were immune to smallpox. Jenner applied the principle to develop a smallpox vaccine using cowpox strains.

Edward Jenner, an English physician, discovered the smallpox vaccine in 1796. He came upon this discovery by noticing that milkmaids who had the cowpox virus, a less threatening disease, did not catch the dangerous smallpox. Jenner then infected an 8-year-old boy with the cowpox. After six weeks, he exposed the boy to the smallpox disease and the boy did not show any smallpox related symptoms.Sone fun facts:-Jenner coined the term 'vaccine': 'vaca' means cow in Latin.-Before the vaccine, the death rate of the disease was up to 35%.
