Concept essentials

  • Immunity from memory cells has to be linked to the exact pathogen, cell, molecule or population process involved.
  • The biological effect of immunity from memory cells depends on the sequence from trigger to protective outcome.
  • Clear distinctions within immunity from memory cells prevent confusion with neighbouring immune responses.
  • Evidence for immunity from memory cells is strongest when mechanism and consequence are explained together.
