When vaccines are introduced in our body they produce an antigenic response, and antibody starts work against the antigen, known as a primary immune response. Antibodies are protein molecule produced in our body against an antigen. There are many types of antibodies one of them is memory cell which is responsible for the secondary immune response of the immune system.

The secondary immune response is the response of our immune system when the same antigen attacks again then our antibody produces rapidly antibody and kill them.
