Detailed explanation-1: -Immunoprophylaxis. Immunoprophylaxis against viral illnesses includes the use of vaccines or antibody-containing preparations to provide immune protection against a specific disease.

Detailed explanation-2: -Vaccines stimulate the human body’s own protective immune responses so that, if a person is infected with a pathogen, the immune system can quickly prevent the infection from spreading within the body and causing disease.

Detailed explanation-3: -The main types of vaccines that act in different ways are: Live-attenuated vaccines. Inactivated vaccines. Subunit, recombinant, conjugate, and polysaccharide vaccines.

Detailed explanation-4: -When you get a vaccine, it sparks your immune response, helping your body fight off and remember the germ so it can attack it if the germ ever invades again. And since vaccines are made of very small amounts of weak or dead germs, they won’t make you sick.
