The first known cases of smallpox go back to 1350 BC and the disease has been known for a very long time. Dr. Campbell identified how smallpox is spread. Edward Jenner is credited with developing the smallpox vaccine in 1796.See the Web Links to the left for more information about the history of smallpox.
He had discovered a cure for SMALLPOX which was called Smallpox vaccine... had tested the vaccination on a person called James Phipps .
by giving people something that will help them not to catch the smallpox disease
Yes. He noticed how milkmaids caught cowpox, but didn't get smallpox. Cowpox was similar to smallpox but much milder so didn't kill people who caught it. The milkmaids who had caught cowpox didn't catch smallpox because their body had become immune to it after having cowpox. To test this theory, Jenner took some of the pus from a cowpox spot from a milkmaid and injected it into a boy named James Phipps. He fell ill, but didn't die. He then recovered and Jenner took the pus of a smallpox spot, in a high dose, and then injected this into James phipps. This was very risky because smallpox at the time was very deadly. James Phipps did not fall ill. The cowpox had made him immune to smallpox. This vaccination was done on more and more people to make more people immune to smallpox.
He did it just to make sure his calculations were correct because not everyone is the same
He originally used the cowpox virus (Variolae vacciniae, "smallpox of the cow" in Latin). At some point the virus used mutated to a slightly different form now known as Vacciniavirus.It's not a coincidence that the word "vaccine" looks a lot like Vaccinia.
Edward Jenner introduced a smallpox vaccine in 1796. He noticed that milkmaids rarely got smallpox and correctly surmised that exposure to cow pox was protecting them. After modifying the cow pox virus to make it less virulent he sucessfully showed that innoculation with it could prevent small pox infection. The word vaccination is derived from his work by taking the latin word for cow (vacca).
in what year did edward Jenner make the word virus up?
Edward Jenner saw how milkmaids didn't have smallpox because they had cowpox, and didn't die. So he gave a boy a dose of cowpox and he got ill, but didn't die and then he gave him a dose of small pox and he didn't die because he had had cow pox already. (phew!)
