IMMUNOLOGY

Detailed explanation-1: -Natural immunity is acquired from exposure to the disease organism through infection with the actual disease. Vaccine-induced immunity is acquired through the introduction of a killed or weakened form of the disease organism through vaccination.

Detailed explanation-2: -There are two types of adaptive immunity: active and passive. Active Immunity-antibodies that develop in a person’s own immune system after the body is exposed to an antigen through a disease or when you get an immunization (i.e. a flu shot). This type of immunity lasts for a long time.

Detailed explanation-3: -The goal of vaccination is to induce long-term protective immunity, which is a hallmark of adaptive immunity. In contrast, innate immunity does not have immunological memory.

Detailed explanation-4: -Artificial active immunity is the result of vaccination. During a vaccination, a weakened, dead, or partial pathogen is injected into the body. The body then produces antibodies against that pathogen for later use. Common examples of vaccines include Polio, Hepatitis B, Chickenpox, and Smallpox.

Detailed explanation-5: -Artificial active immunity refers to immunity produced by intentional exposure of a person to antigens to produce antibodies and memory cells. For example, the administration of vaccination often leads to artificial active immunity.
