Epidemiology of community-acquired pneumonia hospitalizations and associated complications before and after the implementation of the heptavalent pneumococcal conjugate vaccine in Athens, Greece

We determined the rates of community-acquired pneumonia (CAP)-associated hospitalizations and complications in Athens, over a period covering 4 years before and 4 years after the implementation of the 7-valent pneumococcal vaccine (PCV7) in Greece. PCV7 had no impact on pediatric CAP rates, whereas there was an increase in CAP-associated complications. © The Author 2014.
