Fig. 3From: Pneumococcal vaccination responses in adults with subnormal IgG subclass concentrationsSummation of S. pneumoniae serotype-specific IgG antibodies. We measured the concentration of all serotype-specific antibodies per patient in subnormal IgGSc groups in a PPSV23 responders (IgG1, n = 6; IgG3, n = 15; and IgG1 + IgG3, n = 7) and b PPSV23 non-responders (IgG1, n = 7; IgG3, n = 18; and IgG1 + IgG3, n = 6)Back to article page
