Vaccines are prophylactic or therapeutic antigenic preparations administered to activate the adaptive immune response.

The term 'vaccine' derives from the Latin for cow, an etymology that reflects the 1798 observation by British physician Edward Jenner that prior infection with cowpox protected milkmaids from smallpox. Vaccination takes advantage of immunological memory in that the individual is primed for efficient, rapid response to epitopes associated with disease producing organisms.
