He tested it on a small boy named James by injecting a small amount of smallpox into the boy's arm. He watched him for the next few weeks, he saw that James had a few very weak symptoms of smallpox for a short time but was fine days later.
Others were already using smallpox pus inoculations, Jenner used cowpox pus instead. Others had already tried cowpox pus inoculations on a small scale, but Jenner was the first to scientifically verify its safety and effectiveness then proceed to widespread vaccinations. Note: vaccina is Latin for cow.

What scientific method did Edward Jenner use?
the scientific method is grate
Did Edward Jenner make vaccinations?
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.
What evidence did edward Jenner get to show if his idea was right?
he test it with a vaccine
What did Edward Jenner do to test his idea?
He inoculated an 8 year old boy by introducing infection from a cow into his system. The boy developed a slight fever but was not seriously ill. Jenner then injected him with material containing the disease and no illness followed.
What evidence did edward Jenner get to show that his idea was right?
He tested it on an 8 year old boy and on some of his children.
What was edward Jenner's contribution to science?
Edward Jenner was born in 1749, in Berkeley. He wanted to get rid of small pox for ever so he carried out a simple experiment, which turned out to change everyone's lives for the better. Edward Jenner noticed that cows sometimes got a disease called cowpox. Because the milkmaids had to milk the cows, they often also caught cowpox…but it didn't seem to harm them. Edward Jenner was intrigued - milkmaids that had caught cowpox never seemed to catch the contagious and deadly smallpox, which thousands of people died from. Edward Jenner came up with a theory, that cowpox prevented people from getting smallpox. To test his theory, Edward Jenner needed to find someone who was young and who hadn't caught smallpox or cowpox before. He found a boy called James Phipps (aged 8) and explained his idea. Edward Jenner then took some pus from a milkmaid's cowpox and rubbed it into two small incisions on James's arm. Soon after, James became ill with cowpox but the symptoms didn't last long. 6 weeks later, Jenner took some pus from a smallpox victim and again put it into James's cuts. However, this time James didn't catch the disease. Cowpox was called vaccinia so he called his invention the vaccine.
How did Dr Edward Jenner discover a vaccine for smallpox?
He noticed, in his village where he was a doctor, that the dairymaids (woman who milk the cow) who had previously had Cowpox didn't get Smallpox. He got inspired by that and thought that they might have become immune to it. He also successfully tested this on a boy. One day Edward was studying a milk woman who was milking a cow when he noticed she had cow pox that you get from cows. Smallpox was very common in those days so he started to wonder why most milk woman had not caught it yet? So he decided to test it on someone . he found a little boy just 8 and a bit years old and he agreed to help him. He deliberately gave him cow pox and the boy was ill with cow pox but he got better quickly . next he gave him some pus out of a small pox boil to see if he caught it. The boy was fine and Edward had found the cure.
Why was itimportant for edward Jenner to test his idea before treating lots of children?
He did it just to make sure his calculations were correct because not everyone is the same
Why did Edward Jenner carry out his test on several people instead of on just one person?
Edward Jenner carried out his tests on multiple people because he needed more data to prove his theory on vaccination was correct. In medical science it is required to test on multiple people due to how different each person's body works to prove if a treatment works.
How did Jenner test his prediction?
jenner tested his prediction on a small boy
Can you test positive if you had chickenpox vaccine but never had chickenpox?
A person with a history of chickenpox or history of chickenpox vaccine will typically have a positive antibody test for chickenpox.
Why is the tuberculosis vaccine not routinely offered to patients?
There isn't a vaccine for TB. There's a TB test. And I agree, patients should be tested. Permission has to be given by the patients to conduct the test.
