Question

who discovered vaccination and how

Answer 1

Smallpox vaccine, the first successful vaccine to be developed, was introduced by Edward Jenner in 1796. He followed up his observation that milkmaids who had previously caught cowpox did not later catch smallpox by showing that inoculated cowpox protected against inoculated smallpox.

Answer 2

Edward Jenner had discovered a cure for smallpox! Jenner named this inoculation process, “vaccination”, from the Latin name for cow (vacca) and cowpox (vaccinia).

Vaccination at first had many opponents, but eventually its value became firmly established. Today not only has smallpox been nearly wiped out but you can get vaccinated or immunised against many other diseases too! And it is usually performed right from the birth of the child.
