Secondary Response

• What happens if the same pathogen enters the body again?


  the immune system will produce a quicker, stronger immune response- the secondary response
• What happens in the secondary response?

  • Clonal selection happens faster
  • memory B-cells are activated and divide into plasma cells that produce the right antibody to the antigen.
  • memory T-cells are activated and divide into the correct type of T-cells to kill the cell carrying the antigen
• what cells are activated?

  memory B-cells and memory T-cells
• What does the secondary response OFTEN do?


  gets rid of the pathogen before you begin to show any symptoms (you are immune to the pathogen)
