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: -To trigger an immune response, many vaccines put a weakened or inactivated germ into our bodies. Not mRNA vaccines. Instead, mRNA vaccines use mRNA created in a laboratory to teach our cells how to make a protein-or even just a piece of a protein-that triggers an immune response inside our bodies.

Detailed explanation-3: -Vaccination gives you immunity to a specific pathogen. Immunization is the process of developing immunity. The word usually refers to immunity through vaccination, but it can occur through infection, as well. Inoculation is a synonym for vaccination and immunization.

Detailed explanation-4: -Another way to produce active immunity is by vaccination. Vaccines contain antigens that stimulate the immune system to produce an immune response that is often similar to that produced by the natural infection.
