FIGURE 1.

Median serotype-specific antibody levels in lung transplant candidates before vaccination, after vaccination with 13vPCV, before vaccination with 23vPPV (thus 8 wk after 13vPCV), and after vaccination with 23vPPV. Note that the scale of the y-axis is different for all serotypes. Median antibody levels were significantly higher compared with baseline after vaccination with 13vPCV (Wilcoxon signed ranks test; P < 0.01 for all serotypes). 23vPPV, 23-valent pneumococcal polysaccharide vaccine; 13vPCV, 13-valent pneumococcal conjugate vaccine.
