ac·quired im·mu·ni·ty

resistance resulting from previous exposure of an individual in question to an infectious agent or antigen; it may be active and specific, as a result of naturally acquired (apparent or inapparent) infection or intentional vaccination (artificial active immunity); or it may be passive, being acquired through transfer of antibodies from another person or from an animal, either naturally, as from mother to fetus, or by intentional inoculation (artificial passive immunity).

passive immunity

n.
Immunity acquired by the transfer of antibodies from another individual, as through injection or placental transfer to a fetus.

passive immunization n.

passive immunity

passive immunity

Immunity, especially to specific infections, resulting from the acquisition of ANTIBODIES, either by injection or by transfer through the PLACENTA or ingestion in the breast milk. Sensitized T cells can also confer passive immunity.
