Detailed explanation-1: -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: -After immunization, dendritic cells take up microbial antigens and traffic to draining lymph nodes where they present processed antigens to naïve T cells. These naïve T cells are stimulated to proliferate and differentiate into effector and memory T cells.
Detailed explanation-3: -Vaccination aims to create memory cells. A vaccination basically injects an inactive form of a pathogen into the body. This will activate an immune response and antibody production, which means that memory cells are made. This protects the individual incase the real pathogen enters the blood again.
Detailed explanation-4: -Vaccines contain dead or weakened microbes of a particular disease. When a vaccine is introduced into a healthy body, the body fights and kills them by producing suitable antibodies. These antibodies remain in the body and protects it from the microbe when it invades the body again.
