Pneumococcal Vaccine and Pneumonia
The Question: Does vaccination with the pneumococcal vaccine (PCV7) reduce hospitalizations for community-acquired pneumonia?
The Study: Uruguay began vaccinating children with the 7-valent pneumococcal conjugated vaccine (PCV7) and in 2010 changed to the 10-valent vaccine (PCV10). Pneumococcus is a bacterium that often causes pneumonia. “7 valent” means the vaccine is effective against seven strains of the bacteria, and 10 valent is effective against an additional 3 strains.
The researchers calculated the hospitalization rate for children newborn to fourteen years old for any community-acquired pneumonia. This included both bacterial and viral pneumonia affecting children not in the hospital.
The Results: The results were stunning. Comparing pre-vaccine years to post-vaccine years, the hospitalization rate for any community-acquired pneumonia fell by 78% and for pneumococcal pneumonia by 92%.
Comment: Pneumonia is a one of the most frequent causes of death of children under five years old. Vaccinations, while not perfect, do work. They save lives and lessen the chances of hospitalizations.
