Adaptive immune system exposure leads to immunological memory:

Adaptive immune system exposure leads to immunological memory:

• A. leads to immunological memory
• B. decreases immunological memory
• C. no effect on memory
• D. eliminates memory

Answer: (A)

Exposure to an antigen activates the adaptive immune response and creates memory B cells and memory T cells. These memory cells persist long after the initial encounter and respond much more rapidly and effectively if the same antigen appears again, providing lasting immunological memory. That’s why vaccines work—they expose the immune system to an antigen to build this memory without causing disease. Saying memory decreases, has no effect, or is eliminated does not fit with how memory formation actually happens through the adaptive arm of the immune system.
