Reference: AQA
Formed when a B cell with a complementary antibody is selected and clones after the antigen triggers a primary immune response, so a later infection meets a faster, larger secondary response.
Cells produced in the primary response; memory B and T cells are responsible for the speed and size of the secondary response and mean the person is often immune to that pathogen.
