Detailed explanation-1: -Passive Immunity. Passive immunity is provided when a person is given antibodies to a disease rather than producing them through his or her own immune system. A newborn baby acquires passive immunity from its mother through the placenta.

Detailed explanation-2: -Two types of immunity exist-active and passive: Active immunity occurs when our own immune system is responsible for protecting us from a pathogen. Passive immunity occurs when we are protected from a pathogen by immunity gained from someone else.

Detailed explanation-3: -In passive immunization a person receives antibodies or lymphocytes that have been produced by another individual’s immune system; in active immunization the individual’s own immune system is stimulated to produce antibodies and lymphocytes.

Detailed explanation-4: -Vaccines provide active immunity to disease. Vaccines do not make you sick, but they can trick your body into believing it has a disease, so it can fight the disease. Here is how a vaccination works: The vaccine is administered.

Detailed explanation-5: -Artificially-acquired passive immunity is an immediate, but short-term immunization provided by the injection of antibodies, such as gamma globulin, that are not produced by the recipient’s cells. These antibodies are developed in another individual or animal and then injected into another individual.
