Vaccines are very common among livestock. The earliest record of protective immunity dates from 430 BCE. The word vaccine, and vaccination, actually comes from the name for a pox virus—the cowpox virus, vaccinia, to be exact.https://veteriankey.com/a-brief-history-of-veterinary-vaccines/ https://www.sciencefriday.com/articles/the-origin-of-the-word-vaccine/
