He tried it on a eight year old boy because he was sick.
no they did not agree with the advancement of his medical studies. they potrayed it as wizardry
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.
Edward Jenner did not discover germs, he developed vaccination for smallpox (using cowpox pustules) which was much safer than the inoculation for smallpox (using smallpox pustules) then in use. However he had no idea what actually caused smallpox, only that it was something invisible in the pus from the pustules.
what gave him the idea how to stop the disease
one of his freinds had come down with it and he felt sad for him so he wanted to make him feel better.
It was a new idea and most people thought it was illogical to intentionally make someone sick in order to prevent them from getting sicker.
