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. [4] In humans, maternal antibodies (MatAb) are passed through the placenta to the fetus by an FcRn receptor on placental cells. Explanation of artificial passive immunity [1] Passive immunization is used when there is a high risk of infection and insufficient time for the body to develop its own immune response, or to reduce the symptoms of ongoing or immunosuppressive diseases. Protection from passive immunity diminishes in a relatively short time, usually a few weeks or months. Naturally acquired passive immunity occurs during pregnancy, in which certain antibodies are … [7], Passive immunity is also provided through colostrum and breast milk, which contain IgA antibodies that are transferred to the gut of the infant, providing local protection against disease causing bacteria and viruses until the newborn can synthesize its own antibodies. For example, antibodies passed from the mother to the baby before birth confer passive immunity to the baby for the first 4-6 months of life. An artificial immune system, not to be confused with artificial immunity, is any computing system based off of the various principles, processes and theories of the natural immune system. Nevertheless, passive immunity “can be life saving,” Oltz says. Immunoglobulin therapy continued to be a first line therapy in the treatment of severe respiratory diseases until the 1930s, even after sulfonamides were introduced.[12]. Artificial passive immunity is acquired by injection of either serum from immunized (or infected) individuals or antibody preparations. An example of artificial passive immunity is getting an injection of antisera, which is a suspension of antibody particles. ):S18-S23, Microbiology and Immunology On-Line Textbook, "Passive Immunization - Infectious Diseases", "Influenza prevention and treatment by passive immunization", "Centers for Disease Control and Prevention", Centers for Disease Control and Prevention, "Active and passive immunity, vaccine types, excipients and licensing", "Passive Immunization — History of Vaccines", "Report of the Lancet Special Commission on the relative strengths of diphtheria antitoxic serums", "Centers of Disease Control and Prevention", Table 8-2. vaccination. [18], Prior to the advent of vaccines and antibiotics, specific antitoxin was often the only treatment available for infections such as diphtheria and tetanus. These antibodies are developed in another individual or … Certain pathogens cause disease by secreting an exotoxin: these include tetanus, diphtheria, botulism and cholera—in addition, some infections, for example pertussis, appear to be partly toxin mediated [3,4].In tetanus, the principal toxin (termed tetanospasmin) binds to specific membrane receptors located only on pre-synaptic motor nerve cells. Post-exposure prophylaxis (administered with rabies vaccine). [2] Immunity derived from passive immunization lasts for a few weeks to three to four months.

Immunization is often required shortly following birth to prevent diseases in newborns such as tuberculosis, hepatitis B, polio, and pertussis, however, maternal IgG can inhibit the induction of protective vaccine responses throughout the first year of life. In comparison to humans in which a significant amount of immunoglobulins are transferred transplacentally, dogs have an endotheliochorial placenta with four layers separating fetal and maternal blood. The one exception to passive humoral immunity is the passive transfer of cell-mediated immunity, also called adoptive immunization which involves the transfer of mature circulating lymphocytes.
