Question: What Happens In Naturally Acquired Passive Immunity?

What is an example of artificially acquired passive immunity?

Artificial passive immunity comes from injected antibodies created within a different person or an animal.

These antibody-containing preparations are termed antiserum.

The rabies vaccine and snake antivenom are two examples of antiserums that yield passive immunity..

What is active acquired immunity and passive acquired immunity?

Vaccine Education Center 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.

What are examples of passive immunity?

The recipient will only temporarily benefit from passive immunity for as long as the antibodies persist in their circulation. This type of immunity is short acting, and is typically seen in cases where a patient needs immediate protection from a foreign body and cannot form antibodies quickly enough independently.
