An Introduction to Active Immunity and Passive Immunity

Acquired immunity may be either natural or artificial in nature. Both natural and artificial immunity have passive and active components.

AP Biology: Immune System (First and Second Line of Defense)

Active immunity results from an infection or an immunization, while passive immunity comes from naturally or artificially gaining antibodies. Let's take a closer look at active and passive immunity and the differences between them. Active immunity requires exposure to a pathogen or to the antigen of a pathogen.

Exposure to the antigen leads to the production of antibodies. These antibodies essentially mark a cell for destruction by special blood cells called lymphocytes. Cells involved in active immunity are T cells cytotoxic T cells, helper T cells, memory T cells, and suppressor T cells , B cells memory B cells and plasma cells , and antigen-presenting cells B cells, dendritic cells, and macrophages.

There is a delay between exposure to the antigen and acquiring immunity.

The first exposure leads to what is called a primary response. If a person is exposed to the pathogen again later, the response is much faster and stronger. This is called a secondary response. Active immunity lasts a long time.

It can endure for years or an entire life. There are few side effects of active immunity. It can be implicated in autoimmune diseases and allergies, but generally doesn't cause problems. Passive immunity is conferred from outside the body, so it doesn't require exposure to an infectious agent or its antigen. There is no delay in the action of passive immunity.

Its response to an infectious agent is immediate. Passive immunity is not as long-lasting as active immunity. It is typically only effective for a few days. Home Sitemap.
