Vaccination is the application of antigenic material (vaccine) to stimulate the body's immune system and to develop an immunity to a pathogen (germ).
Smallpox was the first ever disease for which a vaccine was developed. It was invented in 1976 by the English physician<em> Edward Jenner.</em> Jenner was the first person to publish evidence that the vaccine was effective. The name vaccination derives from Latin<em> vacca </em>(cow), because it was derived from a virus affecting cows.
