The secondary immune response is also known as what?

The secondary immune response is known as the memory response because it occurs when the immune system encounters a specific antigen for the second time. During the initial exposure to an antigen, the immune system develops a primary response, during which it generates specific antibodies and memory cells. These memory cells remain in the body, allowing for a quicker and more robust activation of the immune system upon subsequent exposures to the same antigen.

This memory response is characterized by a faster production of antibodies and a higher affinity for the antigen compared to the primary response, due to the prior exposure and the presence of these memory cells. Thus, understanding the concept of the memory response is vital for comprehending how vaccinations work and how the body protects itself against previously encountered pathogens.
