Not really. Antibody levels pretty much always peak after infection has been controlled. Antibodies are not in themselves of great value as a protection against a first infection - their production is too slow. They are there to prevent a second infection with the same organism getting hold and to protect newborn babies (maternal antibodies). And antibody levels, once maximal, tend to remain pretty much the same for years. They decline over decades but pretty slowly. I have removed all new production of B cells from people for up to five years - so that they cannot 'restock' antibody production from new B cells in response to antigen. They continue on the antibody production from the old plasma cells they had at the start. For things like tetanus antibodies there is often hardly any fall at all over the period of B cell depletion.
