Bacterial exotoxins: bacterial proteins (enzymes, destroy host cellular structures. Caused by bacteria that could be found anywhere: usually results in part of the toxin (deactivated), which can be injected in the body to improve the immune response. Small fragments: the virulent parental virus is exposed (good target for antibodies, fractionation (getting the end pieces from the virus, purified subunit vaccine. Artificially (taking antibodies from someone else: used as a drug: active: Artificially (vaccination activating our own cells: both passive and active methods are handled by our acquired immunity, natural modes: Woman exposed to breast cancer: her 2 positive.
