After a vaccine is given,it is possible to determine the antibody titer (the amount of antibody present in a sample of plasma).After the first exposure to a vaccine,a primary response occurs.For a period of several days,no antibodies are present;then the titer rises slowly,followed by first a plateau and then a gradual decline as the antibodies bind to the antigen or simply break down (Fig.31.6B).
