And that means, at least initially, during the latent period, we're going to have a zero concentration of antibody in our blood because we're not going to have those antibodies that can bind specifically to that infecting antigen. However, over time, when the adaptive immune system actually is mobilized, it will have those plasma cells that will be able to produce those antibodies. And at that moment in time, we have the logarithmic phase taken to effect. And what the logarithmic phase describes is these plasma cells producing and releasing the antibodies into our blood. And so we see a sharp increase in our concentration of immunoglobulins. But eventually, we have this leveling off process taking place, and then we have the decline phase.
