The humoral immune response is divided into two phases, primary and secondary. These phases differ in the relative amounts of IgG produced-the secondary response having a significantly higher proportion of IgG relative to IgM. The two phases also differ in the speed with which each occurs after the antigen challenge-the secondary phases is significantly more rapid than the primary phase because of the presence of memory cells in the secondary phase.
