What did eward jenner discover about the relationship between smallpox and cowpox?
cowpox gives immunity to smallpox. Jenner observed that people who worked with cattle and contracted cowpox from them.
First vaccine created by?
The first vaccine was created by Edward Jenner in 1796. He developed the smallpox vaccine by using material taken from cowpox lesions, demonstrating that exposure to cowpox could provide immunity against smallpox. This groundbreaking work laid the foundation for the field of immunology and vaccination, ultimately leading to the eradication of smallpox.
What year was the smallpox medicine invented?
Edward Jenner developed vaccine against smallpox in 1798. He used cowpox virus containing fluid for the same.
How did jenner know to use the cowpox disease to produce immunity to smallpox?
The observation that milkmaids almost never got smallpox.
What was the name of the boy that Edward Jenner tested to see if you get cowpox if it would stop smallpox?
Edward Jenner tested his smallpox vaccine on a young boy named James Phipps. In 1796, Jenner inoculated Phipps with material taken from a cowpox sore, which led to the discovery that exposure to cowpox could provide immunity against smallpox. This groundbreaking experiment laid the foundation for the development of the smallpox vaccine.
Why the milkmaids did not get infected with smallpox?
Well, I think it is the case that cowpox is just a lesser, bovine version of smallpox. Milk maids would get cowpox simply because they were exposed to cattle constantly, much more than the average person, who was more likely to get smallpox than cowcox. A scientist called Edward Jenner observed that milk maids, who often got cowpox, never seemed to get smallpox. This was because milk maids would develop immunity to cowpox (and therefore smallpox) once they had fallen ill and recovered from cowpox. He then tested this theory on a young boy. He did this by injecting cowpox into the boy's blood stream; the boy then fell ill with cowpox. After the boy recovered from cowpox, the scientist then injected him with the life-threatening disease smallpox. The result proved his theory right; the injection of smallpox into the boy's bloodstream had had no effect on him, because his body had developed immunity to the disease. If you wish to learn more about vaccination and immunities, then research antibodies, antigens and vaccination and the way in which they all work.
What are the cures for smallpox?
The cure for smallpox is cowpox. Cowpox is a mild version of smallpox and is usually not fatal. The smallpox vaccine contains cowpox.
When Jenner developed the first vaccine he was using the observation of milk maids who?
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.
Who developed a vaccination for smallpox?
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

What observations led Jenner to come up with this theory?
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.
How was the smallpox's vaccine discovered?
The smallpox vaccine was the first successful vaccine to be developed. Edward Jenner observed that milkmaids who caught the cowpox virus did not catch smallpox. He started testing by infecting people with actual Cowpox and after successfully finding this to be effective, "mass infecting" people with Cowpox took place. This reduced mortality by Smallpox drastically. Cowpox and Smallpox are closely related but Cowpox only gives the disease in a very mild form in humans. This most likely because it has developed towards cows and not humans. Diseases do not cross the species barrier easily. As a result of the similarities between the two, human bodies start building up an immune respons against both diseases even if only Cowpox is present. Read more at related link below.
