Asubstance that is usually prepared from killed or weakened pathogens or from genetic material and that is introduced into a body to produce immunity is called a(n)

There are four types of immunity that fall under two categories.

Whereas Natural Immunity occurs when a body  is unintentionally exposed to a disease causing agent,  Artificial Immunity is a means by which a body is given resistance to a disease by intentional exposure to small quantities, often deactivated form of the disease.

On the other hand, Passive Immunity is a short-term resistance to a disease caused from the introduction of antibodies from another person or animal, while Active Immunity refers to resistance acquired through the production of antibodies by the immune system  due to the presence of an antigen.

Based on these definitions, if a substance that is usually prepared from killed or weakened pathogens or from genetic material and that is introduced into a body to produce immunity is called Artificially-acquired Active Immunity.
