Explanation:
Detailed explanation-1: -Active immunity is a disease resistance that results from the protection of proteins called antibodies. Examples of active immunity include a person’s resistance to strep throat due to a previous infection or a person’s immunity to polio due to the polio vaccine.
Detailed explanation-2: -Active Immunity results when exposure to a disease organism triggers the immune system to produce antibodies to that disease. Active immunity can be acquired through natural immunity or vaccine-induced immunity.
Detailed explanation-3: -In general, the immune system can be activated to generate two types of immune responses: nonspecific response (innate immunity) and specific adaptive response (acquired immunity).
