Adaptive immunity, Alternatively, is antigen-dependent and antigen-distinct, which means it responds to an exceedingly specific chemical structure(s) (antigen[s]), and will involve a lag time concerning exposure into the antigen and maximal reaction. The significant hallmark of adaptive immunity will be the ability for memory, which enables the host to mount a more rapid and effective immune reaction upon subsequent publicity for the antigen.
