Decline in early childhood respiratory tract infections in the norwegian mother and child cohort study after introduction of pneumococcal conjugate vaccinationArchived
The findings of this population-wide study, describing a declining incidence of respiratory tract infections by year of birth after the implementation of PCV7, confirm the efficacy of PCV7 vaccination in the prevention of AOM and pneumonia that has been shown by earlier randomised controlled trials.

The findings of this population-wide study, describing a declining incidence of respiratory tract infections by year of birth after the implementation of PCV7, confirm the efficacy of PCV7 vaccination in the prevention of AOM and pneumonia that has been shown by earlier randomised controlled trials. The study design and analysis controlled for influence of potentially confounding trends, such as improvement of day-care carriage and decreasing prevalence of smoking during the study period. The inclusion of asthma in the outcome markers was worth of, given that an earlier trial from South Africa had reported an increase in hospital admissions due to asthma symptoms among children immunized with a 9-valent PCV (Klugman KP, et al. N Engl J Med 2003;349:1341). Limitations of the study included potential misclassification through maternal report and selection bias, given that children with follow-up information of up to 36 months might well constitute a distinct group of the cohort.

Four years of universal pneumococcal conjugate infant vaccination in Germany: Impact on incidence of invasive pneumococcal disease and serotype distribution in childrenArchived
16 Aug 2012 - The study compares the incidence and serotype distribution of invasive pneumococcal disease (IPD) for pneumococcal meningitis and non-meningitis IPD in children from 2007 to 2010 with reference to the pre-vaccination period from 1997 to 2001 in Germany.
Nasopharyngeal flora in children with acute otitis media before and after implementation of 7 valent pneumococcal conjugate vaccine in FranceArchived
28 Mar 2012 - This study found a marked reduction in vaccine serotype carriage after PCV7 implementation. The overall pneumococcal, H. influenzae and S. aureus carriage decreased slightly, but not significantly.
