The PPSV23 was associated with a marginally significant reduction risk of bacteremic pneumococcal pneumonia in the age subgroup >=60 years (HR: 0.74; 95% CI: 0.56–0.97; p = 0.031) and immunocompetent persons (HR: 0.72; 95% CI: 0.53–0.98; p = 0.035), but no benefits emerged against all pneumococcal pneumonia and/or all-cause pneumonia.
