Wiktionary
Pronunciation: /vækˈsin/ / /ˈvækˌsin/
adj
Etymology: 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).
- Of, pertaining to, caused by, or characteristic of cowpox.
- Of or pertaining to cowpox as a source of material for vaccination against smallpox; also, of or pertaining to such material used for vaccination.
“I will call upon them: they are healthy children, we can have the vaccine infection from them, and I will inoculate the boy myself.”
- Of, pertaining to, or derived from cattle.
“[M]y play could not have been written but for the work done by Sir Almroth Wright in the theory and practice of securing immunization from bacterial diseases by the inoculation of "vaccines" made of their own bacteria: a practice incorrectly called vaccinetherapy (there is nothing vaccine about it) apparently because it is what vaccination ought to be and is not.”
noun
Etymology: The noun is probably partly: * derived from vaccine (adjective) (see etymology 1); and * borrowed from French vaccine (“cowpox (short for variole vaccine); vaccination against smallpox using material from cowpox”), vaccin (“cowpox material used for smallpox vaccination”), both noun uses of vaccin (adjective), from Latin vaccīnus (see etymology 1). The verb is derived from the noun. Cognates * Italian vaccina * Portuguese vacina * Spanish vacuna
