Vaccine, How Works In The Human Body

A vaccine is a biological preparation that provides active acquired immunity to a particular infectious disease. The terms vaccine and vaccination are derived from Variolae vaccinae known as cow pox. A term devised by Edward Jenner, who by 1798 used it as a title for his research for the development of the concept of vaccines and the creation of the first vaccine to file smallpox.

In 1881, Louis Pasteur proposed that the terms vaccine and vaccination be extended to cover the new protective inoculations that were being developed in Jenner's honor.
