PT- (A) and Prn-specific (B) plasma IgE values in wP- (circles) and aP-primed (triangles) children prebooster (n = 46 and n = 32, respectively) and at 28 days after a low-dose booster (gray symbols) (n = 46 and n = 16, respectively) or a high-dose booster (black symbols) (n = 52 and n = 35, respectively). A horizontal line indicates the geometric mean per group. *, significantly increased values postbooster compared to prebooster; #, significantly increased values in aP-primed children compared to wP-primed children. MFI, mean fluorescence intensity.
