Figure 2.

Pneumococcal OPA titer reverse cumulative distribution curves before and 1 month after PCV13 administration.

PCV13 = 13-valent pneumococcal conjugate vaccine; QIV = quadrivalent inactivated influenza vaccine. Reverse cumulative distribution curves displaying pneumococcal OPA titers for PCV13 serotypes before (solid lines) and after (dotted lines) PCV13 immunization are shown (evaluable immunogenicity population). Black line, PCV13+QIV/placebo; gray line, placebo+QIV/PCV13. Vertical line, OPA lower limit of quantitation titers for each serotype.
