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: -Artificially acquired active immunity is protection produced by intentional exposure of a person to antigens in a vaccine, so as to produce an active and lasting immune response.

Detailed explanation-3: -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-4: -The two types of acquired immunity are adaptive and passive. Adaptive immunity occurs in response to being infected with or vaccinated against a microorganism. The body makes an immune response, which can prevent future infection with the microorganism.

Detailed explanation-5: -Artificially-acquired passive immunity is an immediate, but short-term immunization provided by the injection of antibodies, such as gamma globulin, that are not produced by the recipient’s cells. These antibodies are developed in another individual or animal and then injected into another individual.
