Detailed explanation-1: -How vaccines help. 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: -Vaccines protect everyone If a person infected with a disease comes in contact only with people who are immune (have been vaccinated), the disease will have little opportunity to spread. The type of protection created when most people are vaccinated is called “community immunity” (or herd immunity).
Detailed explanation-3: -Immunization primes the adaptive immune system to produce an immune response without actually being infected. Weakened or killed pathogens or antigenic components of a pathogen are administered to evoke a primary immune response of the adaptive immune system.
Detailed explanation-4: -Vaccines have greatly reduced diseases that once routinely harmed or killed babies, children, and adults. People all over the world-including in the United States-still become seriously ill or even die from diseases that vaccines can help prevent. It is important that you stay up to date on recommended vaccines.
