Q. 25

Who discovered ‘vaccine’ for the first time? Name two diseases which can be prevented by using vaccines.

Answer :

In the year 1796, Sir Edward Jenner carried out an experiment on an eight-year-old boy named James Phipps. Sir Edward took fluid from a cowpox blister and rubbed it on the skin of the boy and the boy recovered. In 1798, the results were finally published and Jenner coined the word vaccine from the Latin 'vacca' for cow.

Smallpox and Polio are the two diseases that can be prevented using vaccines.


The Smallpox vaccine was the first successful vaccine which was developed by Edward Jenner in 1796..
