This is Thomas Jenner. As a child, he loved science. Everyday he would go down to the river banks and look for fossils.
That is an interesting fossil!
At the age of 21, Jenner began training as a doctor. 2 years later Edward started practising to be a physician in his hometown in Berkeley, Gloucestershire.
You are now officially a doctor of Berkeley Health!
Everyone was scared of this horrible disease called smallpox. Country people believed that if anyone caught the mild disease cowpox from cows, they wouldn't get the more serious disease smallpox.
Jenner decided to carry out an experiment to see if the country people's belief was true. He got a sample from someone with cowpox and someone with smallpox. Then he got a boy (that his mother allowed) to test on.
He rubbed some cowpox on the boys hand and he of course got sick, but a few days later, the boy returned fully recovered and healthy. He then rubbed some smallpox on the boy and he did not get sick! All he got was a scab.
The Latin name for cow is 'Vacca' and since it was Jenner's discovery, he chose to call it Vaccinations as cows have just cured a deadly disease
You hoomans so disrespectful of us cows. We give you meat and milk and you don even say tanku!
Plus you now youse ower name for vaccination!
Jenner then vaccinated all the local children with cowpox to prevent them getting the more dangerous smallpox disease.
