2. FIG. 1
Fold-increase of anti-pneumococcal surface protein (PSP) antibody concentrations in bacteraemic children. The ratio of convalescent to acute anti-PSP antibody geometric mean concentration (GMC) is illustrated for each PSP and age group. PcpA, pneumococcal choline-binding protein A; PhtD, pneumococcal histidine triad D; PrtA, serine proteinase precursor A.

3. FIG. 2
Proportion of seroresponders among bacteraemic children by age category. The proportion of bacteraemic children with a ≥2-fold increase in anti-PSP antibody concentration is illustrated for each pneumococcal surface protein and age group. PcpA, pneumococcal choline-binding protein A; PhtD, pneumococcal histidine triad D; PrtA, serine proteinase precursor A.
