Secondary immune response

• What is the secondary immune response?


  • relies on memory cells and can protect us against the identical antigen for decades
  • on re-exposure to the antigen after a short latent period, memory cells undergo clonal expansion, but faster than in the primary response
  • antibodies are made more quickly and their concentration is up to 100 times that of the primary response
  • they remain in high concentration for longer and no symptoms develop
• Label this graph of the secondary immune response

  A) concentration of antibodies

  B) time

  C) initial exposure
