Detailed explanation-1: -Vaccines contain weakened or inactive parts of a particular organism (antigen) that triggers an immune response within the body. Newer vaccines contain the blueprint for producing antigens rather than the antigen itself.
Detailed explanation-2: -Live-attenuated vaccines Live vaccines use a weakened (or attenuated) form of the germ that causes a disease. Because these vaccines are so similar to the natural infection that they help prevent, they create a strong and long-lasting immune response.
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.
Detailed explanation-4: -See the Vaccine and Immunization Glossary of Terms. Immunity: Protection from an infectious disease. If you are immune to a disease, you can be exposed to it without becoming infected. Vaccine: A preparation that is used to stimulate the body’s immune response against diseases.
