Passive Immunity- Definition, Characteristics, Types, Examples


Passive immunity is a type of immunity that does not involve the production of antibodies by the immune system of the individual. Instead, it relies on the transfer of antibodies from another source, such as another person or an animal, into the body of the recipient. These antibodies can bind to and neutralize the antigens of foreign invaders, such as bacteria, viruses, toxins, or parasites, and protect the individual from infection or disease.
