Genetic Variation in the Magnitude and Longevity of the IgG Subclass Response to a Diphtheria-Tetanus-Acellular Pertussis (DTaP) Vaccine in Mice.

In contrast, the longevity of IgG subclasses to the same vaccine antigen did not correlate with each other, or only with a low to medium level of significance ( Figure 2 b and Figure S4 ), e.g., a longer duration of PT-specific IgG1 did not point toward a longer duration of IgG2b nor IgG3 to PT.
