IMMUNOLOGY

Detailed explanation-1: -Vaccine-induced immunity is acquired through the introduction of a killed or weakened form of the disease organism through vaccination.

Detailed explanation-2: -Vaccines provide active immunity to disease. Vaccines do not make you sick, but they can trick your body into believing it has a disease, so it can fight the disease. Here is how a vaccination works: The vaccine is administered.

Detailed explanation-3: -Varicella-Zoster and hepatitis B gammaglobulin (IgG) preparations are examples of passive immunity which have considerable applications to the occupational health situation.

Detailed explanation-4: -Active immunization typically involves administration of a primary series of injections of one or more doses of vaccine to “prime” the immune system and generate effector proteins (antibodies) and cells.

Detailed explanation-5: -Two types of immunity exist-active and passive: Active immunity occurs when our own immune system is responsible for protecting us from a pathogen. Passive immunity occurs when we are protected from a pathogen by immunity gained from someone else.
