secondary immune response

• if the same antigen enters the body again, the immune response will be quicker and stronger - the secondary response
• clonal selection can happen faster
• memory B-cells are activated and divide into plasma cells which release the specific antibody for the antigen
• memory T-cells are activated and divide into the correct type of T-cell to kill the cell carrying the antigen
• often the secondary response removes the pathogen before you show symptoms
