The History of Vaccination

Edward Jenner, an English physician, is credited with developing the first vaccine in 1796. He used cowpox to immunize against smallpox.

Smallpox was the first disease to be prevented by a vaccine. Edward Jenner's vaccine, developed in 1796, was effective in preventing smallpox infection.

Jonas Salk, an American virologist, developed the first polio vaccine in 1955. His vaccine was an inactivated poliovirus vaccine, which was administered by injection.

The measles vaccine was introduced in 1963. It was a live attenuated vaccine, which was administered by injection.

Smallpox was the first disease to be eradicated globally through vaccination. The World Health Organization (WHO) declared smallpox eradicated in 1980.
