Detailed explanation-1: -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-2: -Vaccine-induced immunity Also known as artificial active immunity, a person can build resistance to a disease following an immunization. Immunization is the process that happens in the body following the administration of a vaccine aimed at conferring immunity to a pathogen.

Detailed explanation-3: -Adaptive immunity: Adaptive (or active) immunity develops throughout our lives. We develop adaptive immunity when we’re exposed to diseases or when we’re immunized against them with vaccines. Passive immunity: Passive immunity is “borrowed” from another source and it lasts for a short time.

Detailed explanation-4: -The acquired immune system, with help from the innate system, makes special proteins (called antibodies) to protect your body from a specific invader. These antibodies are developed by cells called B lymphocytes after the body has been exposed to the invader.

Detailed explanation-5: -(ih-MYOO-nih-tee) In medicine, the immune system’s way of protecting the body against an infectious disease. The three types of immunity are innate, adaptive, and passive.
