Detailed explanation-1: -Memory T and B cells remain, however, and maintain a heightened ability to mount a response to a recurrence of infection with the same pathogen. The antibody and memory T cells remaining in an immunized individual also prevent the activation of naive B and T cells by the same antigen.

Detailed explanation-2: -Lymphocytes are cells that circulate in your blood that are part of the immune system. There are two main types lymphocytes: T cells and B cells. B cells produce antibody molecules that can latch on and destroy invading viruses or bacteria.

Detailed explanation-3: -In addition to the spleen and lymph nodes, memory B cells are found in the bone marrow, Peyers’ patches, gingiva, mucosal epithelium of tonsils, the lamina propria of the gastro-intestinal tract, and in the circulation (67, 71–76).

Detailed explanation-4: -Memory B cells, like memory T cells, help the immune system respond more quickly to future invasions by the same agent.

Detailed explanation-5: -B lymphocytes are the cells of the immune system that make antibodies to invading pathogens like viruses. They form memory cells that remember the same pathogen for faster antibody production in future infections.
