Geometric mean concentrations (GMC) and 95% confidence interval (CI) of the serological immunoglobulin (Ig)G responses to DTaP vaccine antigens; DT (diphtheria toxoid), TT (tetanus toxoid) and PT (pertussis toxoid) in stringent otitis-prone (sOP) (n = 15) and non-otitis-prone (NOP) (n = 20) children.
