Passive immunization
Passive immunization imparts immediate, but not long-lasting, protection against a pathogen and may arise naturally, such as when a fetus receives antibodies from the mother across the placenta or when a breast-feeding infant ingests antibodies in the mother's milk. Passive immunization against a particular pathogen, such as the hepatitis B virus (HBV), also can be conferred artificially. A person lacking immunity to HBV can receive a preparation called immune serum globulin that contains antibodies formed against the virus. These antibodies are obtained from serum taken from animal or human donors who previously were infected by or immunized against the virus.
