Question

What disadvantages would there be if adaptive immunity were to be engaged as quickly at innate immunity?

Answer 1

Ans: Adaptive immunity is triggered when an infection eludes the innate defense mechanisms and generates a threshold dose of antigen. This antigen then initiates an adaptive immune response, which becomes effective only after several days. The time is required for antigen- specific T cells and B cells to locate their specific foreign antigen, to proliferate, and to differentiate into armed effector cells. in my opinion, if adaptive immunity were to be engaged as quickly as innate immunity, the response would be very fast and vigorous and hypersensity like reaction may occur.
