Edward Jenner was a country Doctor Who had studied nature and his natural surroundings since childhood. He had always been fascinated by the rural old wives tale that milkmaids could not get smallpox. He believed that there was a connection between the fact that milkmaids only got a weak version of smallpox - the non-life threatening cowpox - but did not get smallpox itself. A milkmaid who caught cowpox got blisters on her hands and Jenner concluded that it must be the pus in the blisters that somehow protected the milkmaids.
Jenner decided to try out a theory he had developed. A young boy called James Phipps would be his guinea pig. He took some pus from cowpox blisters found on the hand of a milkmaid called Sarah. She had milked a cow called Blossom and had developed the tell-tale blisters. Jenner 'injected' some of the pus into James. This process he repeated over a number of days gradually increasing the amount of pus he put into the boy. He then deliberately injected Phipps with smallpox. James became ill but after a few days made a full recovery with no side effects. It seemed that Jenner had made a brilliant discovery.
I give up! What DID Ed Jenner think about cowpox??
milkmaids and farmers where much less likely to get smallpox. The symptoms for cowpox and smallpox are similar initially, so he theorized that cowpox was a less severe variant of smallpox.
He saw that cow maids don't get small pox, so he investigated and he found that when someone have the mild cowpox disease they don't get smallpox, later he invented the first vaccine.
Edward Jenner Began his theory on a Farmers 8 yr old son, after the child had cowpox, Jenner tried again and again to infect he boy with Smallpox but his child never got sick!
James Phipps
He tried it on a eight year old boy because he was sick.
Edward Jenner tried his earliest vaccination attempts on a boy named James Phipps. After numerous injections of the cowpox virus, the boy recovered rapidly from exposure to smallpox. See the related link for more information
It was on May 14, 196, that Edward Jenner from Berkely, Gloucestershire, England first atempt to create a vaccine. He extracted the contents of a pustule fro the arm of a cowpox infected milkmaid, Sarah Nelmen, and injected it into the arm of eight-year-old James Phipps. As Jenner expected, immunization or vaccination with the cowpox virus caused only mild symptoms in the boy. When he subsequently inoculated the boy with smalllpox virus, the boy showed no symtomps of disease. The procedure is repeated to many paptients. By 1800 the practice is known as variolationhad began in America and by 1805 Napoleon Bonaparte had oredered all French solders to be vaccinated.
what gave him the idea how to stop the disease
I'll not try another experiment like that!
trial, test try out
no he does not.
No, Jacob Black doe not try to kill Edward Cullen
Yes, Harold Godwinson did not try to kill King Edward. In fact, Harold was a prominent English nobleman who served as an advisor to King Edward before becoming King of England himself.
Yes they do eventually try.
