Monitoring of community-acquired pneumonia hospitalisations before the introduction of pneumococcal conjugate vaccine into Polish National Immunisation Programme (2009-2016): A nationwide retrospective database analysis

摘要

Purpose: Community-acquired pneumonia (CAP) is a common infection with significant morbidity and mortality. In January 2017, Poland introduced pneumococcal conjugate vaccine (PCV) into their national immunisation programme to protect children against invasive pneumococcal disease. This study was designed to investigate pneumonia-related hospitalisation rates and trends from 2009 to 2016 prior to the introduction of nationally funded PCV vaccination.
