Detailed explanation-1: -Once B cells and T cells are formed, a few of those cells will multiply and provide “memory” for your immune system. This allows your immune system to respond faster and more efficiently the next time you are exposed to the same antigen.
Detailed explanation-2: -Vaccines use a weakened or dead form of a pathogen or subunits from it that are known to stimulate the immune system to generate an immune response. Vaccines are typically administered using an injection, but some are also routinely administered via the mouth or as a nasal spray.
Detailed explanation-3: -Passive Immunity. Passive immunity is provided when a person is given antibodies to a disease rather than producing them through his or her own immune system.
Detailed explanation-4: -Because our memory cells are “experienced, ” we will respond to a second (or subsequent) encounter more quickly. Whereas in a primary encounter, antibodies are not generated for several days, during a memory response antibodies appear in just a few days.
