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: -Also known as artificial active immunity, vaccine-induced immunity gives our bodies a controlled way to create an immune response. When a weakened or dead form of a disease organism is injected into our bodies or administered via the mouth or as a nasal spray, that’s vaccine-induced immunity.

Detailed explanation-3: -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-4: -Active artificially acquired immunity refers to any immunization with an antigen. During artificially acquired active immunity, one is immunized with one or more of the following: attenuated microbes, killed organisms, fragmented microorganisms, or antigens produced by recombinant DNA technology, or toxoids.

Detailed explanation-5: -Because vaccines are made using parts of the viruses and bacteria that cause disease, the ingredient that is the active component of the vaccine that induces immunity is natural.

Detailed explanation-6: -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.
