Detailed explanation-1: -How do vaccines work? Vaccines help your immune system fight infections faster and more effectively. 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.

Detailed explanation-2: -Vaccines train your immune system to create antibodies, just as it does when it’s exposed to a disease. However, because vaccines contain only killed or weakened forms of germs like viruses or bacteria, they do not cause the disease or put you at risk of its complications.

Detailed explanation-3: -Vaccination is the injection of a dead or weakened organism that forms immunity against that organism in the body. Immunization is the process by which an animal or a person stays protected from diseases.

Detailed explanation-4: -Vaccines mimic the virus or bacteria that causes disease and triggers the body’s creation of antibodies. These antibodies will provide protection once a person is infected with the actual disease-causing virus or bacteria.
