ANATOMY

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: -If you’re wondering why vaccine-induced immunity is considered a form of active immunity, while immune globulin shots are passive, it is because immune globulin is a substance made up of antibodies that are naturally made by the body to provide protection from certain diseases.

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: -Several products have been approved by the U.S. Food and Drug Administration (FDA) for passive immunization and immunotherapy, including antibodies against botulism, diphtheria, hepatitis A, hepatitis B, measles, rabies, Kawasaki disease, and tetanus.

Detailed explanation-5: -Acquired immunity makes your immune system stronger. Vaccines, for example, expose your immune system to small amounts of pathogens that won’t make you sick. Your immune system learns how to recognize those germs, so the next time it encounters them, your immune system will know how to naturally fight them off.
