The History of Vaccine

Inoculation with various types of material from organisms has been around for centuries. Have you ever wondered where vaccines got their popularity? In 1796 Edward Jenner introduced cowpox in 13 people to help prevent them from being infected by smallpox. He did so by taking the pustules or scabs produced by the infection from people who currently were exposed to cowpox. This conferred immunity against the smallpox. Thus vaccine can be broken down into its Latin form vacca meaning cow. And now you know!
