active immunities การใช้

• Both provide active immunity against a future infection.
• In Europe, the induction of active immunity emerged in an attempt to contain smallpox.
• The use of vaccine is the only way to ensure that gilts develop active immunity before conception.
• A vaccine induces active immunity when antigens are injected into an animal that cause it to produce desired antibodies itself.
• A vaccine is an antigenic preparation used to produce active immunity to a disease, in order to prevent or reduce the effects of infection by any natural or " wild " pathogen.
• Passive immunity provides immediate protection, but the body does not develop memory, therefore the patient is at risk of being infected by the same pathogen later unless they acquire active immunity or vaccination.

• Vaccines should be administered several weeks before conception to provide immunity throughout the susceptible period of gestation but after the disappearance of passively acquired colostral antibody, which could interfere with the development of active immunity.
• A "'vaccine "'is an antigenic preparation used to produce active immunity to a disease, in order to prevent or ameliorate the effects of infection by any natural or " wild " strain of the organism.
• The first course of vaccinations ( commonly anti-clostridial ) is commonly given at an age of about 10 to 12 weeks; i . e . when the concentration of maternal antibodies passively acquired via colostrum is expected to have fallen low enough to permit development of active immunity.
• :If my understanding is correct, memory B cells and memory T cells are where active immunity is " stored ", so that implies they can live at least as long as the organism they're a part of, since immunity can be lifelong .-- talk ) 18 : 27, 21 September 2015 ( UTC)
• Both naturally and artificially acquired immunity can be further subdivided depending on whether immunity is induced in the host or passively transferred from an immune host .'Passive immunity'is acquired through transfer of antibodies or activated T-cells from an immune host, and is short lived usually lasting only a few months whereas'active immunity'is induced in the host itself by antigen and lasts much longer, sometimes lifelong.
