During an infection your T and B cells that recognize the bug that's infecting you will divide ALOT, such that you may start with as few as 10 cells that recognize a specific part of the bug but end with over 100,000 cells. T cells will do there jobs in helping to rid the body of the infection and B cells will start producing antibodies against them. After the infection is cleared the T and B cell populations will shrink and will become memory cells. These memory populations will live for a very long time, in some cases the rest of your life. While these cells are hanging out waiting for the next infection they will become better responders to the bug they recognize. So once you're reinfected they can respond faster and with more precision.
