The secondary immune response is faster and stronger than the primary response. This is because memory B and T cells have already been produced during the primary response and are able to quickly recognize and respond to the antigen upon re-exposure. In contrast, during the primary response, it takes time for the immune system to produce specific B and T cells for a first-time encounter with the antigen.
