Question

Name the kind of immunity attained when instead of antibodies weakened antigens are introduced into the body.

Answer 1

The kind of immunity attained when weakened antigens (also called attenuated or modified antigens) are introduced into the body is called artificial active immunity.

This type of immunity is achieved through vaccination by injecting small amounts of weakened or killed antigens (vaccines) into an individual, which stimulates the body’s immune system to produce antibodies and memory cells. This prepares the immune system to respond rapidly and effectively if exposed to the actual pathogen in the future.
