Vaccinations Don’t Eliminate Pneumonia Risk, BU Study Finds

Children and adults in Germany with chronic medical conditions continue to have increased rates of all-cause pneumonia despite the introduction of widespread pneumococcal vaccination nearly a decade ago, a study led by researchers from Boston University School of Public Health (BUSPH) and Boston University School of Medicine (BUSM) has found.

The study, in the journal BMC Infectious Diseases, found that all-cause pneumonia rates among children and adults with “at-risk” conditions were 1.7 times the rates of their healthy counterparts. The rates for children and adults with “high-risk” conditions were 1.8 to 4.1 times the rates of healthy counterparts.

Infection with Streptococcus pneumoniae (pneumococcus) has been reported to be one of the most common causes of severe pneumonia among adults throughout Europe. While childhood immunization has led to declines in the incidence of invasive pneumococcal disease in U.S. adults — via indirect or “herd” effects — the impact of childhood vaccination in western Europe has been more variable, the authors said.

“German children and adults with a spectrum of medical conditions [. . .] continue to suffer a disproportionate burden of pneumonia in the era of widespread pneumococcal vaccination,” according to the study.
