IMMUNOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -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.

Detailed explanation-3: -Passive immunity can occur naturally, such as when an infant receives a mother’s antibodies through the placenta or breast milk, or artificially, such as when a person receives antibodies in the form of an injection (gamma globulin injection).

Detailed explanation-4: -Passive immunization with serum or globulin (antibodies) from immune persons has been used to prevent viral infections. Immunoglobulins, such as those used against hepatitis and respiratory syncytial virus, are effective only for prevention, not for treatment.

Detailed explanation-5: -A type of immunity that occurs when a person is given antibodies rather than making them through his or her own immune system. For example, passive immunity occurs when a baby receives a mother’s antibodies through the placenta or breast milk.

Detailed explanation-6: -Artificial passive immunization is the injection of preformed antibody solution when a patient is incapable of producing antibodies fast enough to combat a disease. Natural passive immunization is the transfer of antibodies through the placenta of a pregnant woman to the fetus.
