Active immunity provides resistance by actively participating in producing memory b cells and t cells after being exposed to an antigen.

What is active acquired immunity?

It is the reaction of the immune system to produce antibodies when exposed to a disease-causing organism. It is a lifetime immunity (long-lasting immunity). But it is slow and takes time to show its fully effective response.

It is of two types

Natural active immunity:

It is developed from the exposure of an organism causing disease through natural infection.

Ex: lifetime immunity acquired by an individual after recovering from infections like smallpox, chicken pox, etc.

Artificial active immunity:

The immunity developed by an individual due to the inoculation of weakened antigens into the body.

Ex: immunity develops due to vaccination.

During a primary immune response, it produces effector cells and long-lived memory cells. Memory B and T cells are antigen-specific and on encountering antigen again they show a more rapid and effective immune response known as a secondary immune response.

Hence active acquired immunity is an immunity that was acquired during a lifetime and produces memory b and t cells after being exposed to antigen.
