Quizplus · Accepted Answer

This statement is true. Immunological memory is formed when the immune system is exposed to an antigen, and specific leukocytes and circulating antibodies remember the antigen and can quickly mount a response upon re-exposure. This is the basis for the effectiveness of vaccines, which expose the immune system to a harmless form of an antigen to create immunological memory and provide protection against the actual pathogen.
