A vaccine that induces an immune response, which more closely resembles that of a natural infection, than that elicited by killed vaccines, as the organisms contained therein actively reproduce until held in check by the recipient's own antibodies, thus often conferring life-long immunity Examples Measles, mumps, polio, rubella.
