Now, the response will be different. The question is why? Well, because during the primary response not only was the adaptive immune system producing plasma cells but it was also producing memory cells. And recall that memory cells are those white blood cells that actually store a copy of that antibody for that specific antigen. And the reason the memory b cells store that antibody is in case reinfection actually ever reoccurs actually ever takes place again. So what happens when the body is reinfected by the same type of pathogen?
