inoculation
ih-nok-yuh-LAY-shuhn
/ɪˌnɒkjʊˈleɪʃən/
The action of inoculating or of being inoculated; vaccination.
Historically, inoculation specifically referred to 'variolation' (using actual smallpox material), while vaccination (from 'vacca', cow) used the milder cowpox.
The story behind the word. This word has a surprising agricultural origin. It comes from the Latin 'inoculare', which meant to 'graft a bud' from one plant onto another. Doctors adopted the term because early smallpox prevention involved 'grafting' the disease into a healthy person's skin.
