<h3>Background</h3> Although recent reports suggest that the incidence of parapneumonic empyema has increased in several regions USA, national trends disease burden are unknown. National hospitalisations and changes by associated pathogens were examined. <h3>Methods</h3> hospitalisation data (1996–2008) analysed rates estimated using census estimates as denominators. Incidence rate ratios (IRR) compared 2008 with 1996 rates. Discharge diagnosis codes used to characterise hospitalisations....

The incidence of childhood pneumonia decreased following introduction 7-valent pneumococcal conjugate vaccine (PCV7) in the United States. Recent regional reports suggest an increase complicated by empyema. We assessed whether early decreases hospitalization rates were sustained and trends such hospitalizations empyema States children aged <5 years.Nationwide Inpatient Sample Census data used to calculate annual all-cause for pre-PCV7 (1996-1999) post-PCV7 years (2001-2007) analyze national...

OBJECTIVE. Streptococcus pneumoniae is an important cause of otitis media in children. In this study we estimated the effect routine childhood immunization with heptavalent pneumococcal conjugate vaccine on frequent (3 episodes 6 months or 4 1 year) and pressure-equalizing tube insertions.

Background. Although hospitalizations due to invasive pneumococcal disease decreased after routine vaccination of young children with a 7-valent conjugate vaccine (PCV7) began in 2000, information on the trends meningitis is limited.

Background Pneumococcal conjugate vaccines (PCVs) have the potential to prevent pneumococcal disease through direct and indirect protection. This multicentre European study estimated effects of 5-year childhood PCV10 and/or PCV13 programmes on invasive (IPD) in older adults across 13 sites 10 countries, support decision-making vaccination policies. Methods For each site we calculated IPD incidence rate ratios (IRR) people aged ≥65 years by serotype for PCV10/13 year (2011–2015) compared with...

Background The ten-valent pneumococcal conjugate vaccine (PCV10) was introduced into the Finnish National Vaccination Program (NVP) in September 2010 with a 2+1 schedule (3, 5, 12 months) without catch-up vaccinations. We evaluated direct and indirect effects of PCV10 on invasive disease (IPD) among children ≤5 years age during first three after NVP introduction. Methods conducted population-based, observational follow-up study. cohort vaccine-eligible (all born June 1, or later) followed...
