Quantification of postimmunization, antipneumococcal polysaccharide serum IgG (a), IgA (b), and IgM (c) antibody levels. The adults received a single dose of Pnc7 (n = 20; triangles), and the 12-month-old toddlers received a single dose (n = 23; closed circles), followed by a second dose (n = 23; open circles) 2 months later. The levels of antibodies against pneumococcal serotypes 4, 14, and 23F were quantified by ELISA. The data are plotted as the log of the individual antibody concentrations (in μg/ml), and the bars represent the GMCs.
