FIGURE 3.

Median antipneumococcal antibody levels in lung transplant recipients. Antibody levels are shown before vaccination, after vaccination (with 23vPPV, ie, after both vaccines in the current study) and 1 y after the vaccinations. Blue bars represent lung transplant recipients from the current study (n = 15), and green bars represent lung transplant recipients from a previously described cohort, who were vaccinated with 23vPPV alone (n = 49). All recipients had been vaccinated with 23vPPV before transplantation as well. 23vPPV, 23-valent pneumococcal polysaccharide vaccine.
