1 what type of immunity results from vaccination

Active Immunity results when exposure to a disease organism triggers the immune system to produce antibodies to that disease. Active immunity can be acquired through natural immunity or vaccine-induced immunity.

Either way, if an immune person comes into contact with that disease in the future, their immune system will recognize it and immediately produce the antibodies needed to fight it. Active immunity is long-lasting, and sometimes life-long. Passive immunity is provided when a person is given antibodies to a disease rather than producing them through his or her own immune system.

The major advantage to passive immunity is that protection is immediate, whereas active immunity takes time usually several weeks to develop. However, passive immunity lasts only for a few weeks or months. They realized that they needed to immunize large animals, such as horses and sheep, to produce enough antitoxin to protect humans. Which of the following is not a disadvantage of passive immunization? True or false? In certain cases, passive and active immunization can be used together.

Vaccines are given to prevent and eventually wipe out diseases. When a vaccine is given to a significant portion of the population, it protects those who receive the vaccine as well as those who cannot receive the vaccine.

This concept is called "herd immunity. This herd immunity protects the unvaccinated population from contagious spread from person to person diseases for which there is a vaccine.

Adaptive Immunity Adaptive immunity is protection that your body builds when it meets and remembers antigens, which is another name for germs and other foreign substances in the body. There are two types of adaptive immunity: active and passive.

Active Immunity - antibodies that develop in a person's own immune system after the body is exposed to an antigen through a disease or when you get an immunization i. This type of immunity lasts for a long time.
