## Definitions
1. Inoculation with a vaccine, in order to protect from a particular disease or strain of disease.

## Etymology
From vaccinia, a cowpox infection. Ultimately from Latin vacca (“cow”). Coined by Edward Jenner (1749-1823) in 1798. Jenner infected people with weakened cowpox viruses (vaccinia), to immunise them against smallpox. It is now known that vaccinia and cow pox are separate conditions, but at the time of Jenner, they were considered the same condition.
