Abstract(s)

Pneumonia is an important cause of morbidity, mortality and expenditure of health resources. Since the introduction of conjugated pneumococcal vaccines (PCV) in infant immunization programs in 2000s, there is consistent evidence of pneumonia reduction in vaccinated children1. Limited data are available on indirect effect of infant immunization on pneumonia burden in unvaccinated population subgroups. This study aims to assess the indirect effect of the introduction of infant 7-valent (PCV7) and 13-valent (PCV13) pneumococcal conjugated vaccines on the pneumonia burden among adults aged 65 or more years in Portugal, comparing trends in Pneumococcal Pneumonia (PP) hospitalization rates before and after the introduction of the PCV7/PCV13.
