IMMUNOLOGY

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: -Immunization is the process whereby a person is made immune or resistant to an infectious disease, typically by the administration of a vaccine. Vaccines stimulate the body’s own immune system to protect the person against subsequent infection or disease.

Detailed explanation-3: -Immunity means com-plete resistance to disease; immune means not subject to attack by a path-ogenic organism or virus.

Detailed explanation-4: -A type of immunity that develops when a person’s immune system responds to a foreign substance or microorganism, or that occurs after a person receives antibodies from another source. The two types of acquired immunity are adaptive and passive.

Detailed explanation-5: -Types of immunity: Active natural: Body produces antibodies in response to exposure to a live pathogen. Active artificial: Body produces antibodies in response to a vaccine. Passive natural: Antibodies are passed from the mom to her baby through the placenta and breastmilk.
