cowpox gives immunity to smallpox. Jenner observed that people who worked with cattle and contracted cowpox from them.
Louis PasteurEdward Jenner found that people who contracted the cowpox virus didn't contract smallpox so he tested it out on a farmer's son who had contracted smallpox that week and he applied the liquid inside a cowpox sore to a cut and then after he healed from cowpox, he injected the liquid from a smallpox sore and the boy didn't contract smallpox.Which is how he found the vaccine...Note: Developed not invented

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.

Edward Jenner observed that milkmaids who had contracted cowpox, a less severe disease, did not get smallpox, a much more deadly illness. He hypothesized that exposure to cowpox could provide immunity against smallpox. To test this, he inoculated a young boy with material taken from a cowpox sore, and later exposed him to smallpox, finding that he did not contract the disease. This led Jenner to develop the first successful smallpox vaccine, laying the groundwork for immunology.
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.
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's central question in his smallpox experiment was whether exposure to cowpox could provide immunity against smallpox. He hypothesized that since milkmaids who contracted cowpox appeared to be immune to smallpox, inoculating individuals with cowpox could protect them from the more dangerous disease. This led him to conduct experiments, ultimately demonstrating that cowpox inoculation could indeed confer immunity to smallpox. Jenner's work laid the foundation for the development of vaccines.
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.
