This is an example of passive immunization, where pre-formed antibodies are transferred from one individual (the rabbit) to another (the human) to provide immediate protection against a pathogen. Active immunization involves stimulating a person's own immune system to produce antibodies by giving them a vaccine. Innate immunity is the body's natural defense mechanisms against pathogens, and natural immunity refers to immunity that is acquired through natural exposure to a pathogen. Alloimmunity refers to immune responses against tissues and cells from another individual of the same species.
