Question
Which of the following is used during a second interaction with an antigen, and results in a heightened state of immunity after? Group of answer choicesImmunological MemoryTolerancePathogenInnate Immunity
Solution
The correct answer is Immunological Memory. This is the aspect of the immune system that learns from the first encounter with an antigen and responds more effectively during subsequent encounters. This is why, for example, if you've had chickenpox once, you're generally immune for life - your body 'remembers' the antigen and can mount an effective response immediately if it encounters it again.
