Word Origin & History

vaccination 
1803, used by British physician Edward Jenner for the technique he devised of preventing smallpox by injecting people with the cowpox virus (variolæ vaccinæ), from vaccine (adj.) "pertaining to cows, from cows" (1798), from L. vaccinus "from cows," from vacca "cow" (bos being originally "ox," "a loan word from a rural dialect" according to Buck, who cites Umbrian bue). "The use of the term for diseases other than smallpox is due to Pasteur (Trans. 7th Session Internat. Med. Congr. (1881) I.90)" [OED]. The noun vaccine "matter used in vaccination" is recorded from 1846; vaccinate is an 1803 coinage.
