In doing so, they can often gain an advantage over other bacteria, and thus reproduce more. With active immunity, antigens enter the body and the body responds by making its own antibodies and B-memory cells .In this case, immunity is longer lived although duration depends on the persistence of the antigen and the memory cells in the body.
