And so what that means is the latent period will be much shorter because our adaptive immune system already consists of those memory B cells and memory T cells that contain that specific antibody. And so the latent period will be much shorter. On top of that, the concentration of the peak, the highest amount, the highest concentration of immunoglobulins that we produce will be much greater than in the primary case as a result of the presence of those memory cells. And also notice what happens in this phase. In this case, we have a very sharp decline in the concentration and it drops to very low undetectable level. But in this particular case, it doesn't drop to low value, it remains relatively high.
