Where it comes from
Learned borrowing from Latin vaccīnus (“of or derived from a cow”), from vacca (“cow (female cattle)”) + -īnus (suffix meaning ‘of or pertaining to’ forming adjectives). Sense 1 refers to the early use of the cowpox virus as a vaccination against smallpox: see New Latin variolae vaccīnae (“cowpox”, plural, literally “infectious diseases of cattle causing pustules”), coined by the British physician and scientist Edward Jenner (1749–1823).
