Pneumococcus is the most important cause of bacterial pneumonia in children.
Vaccinating against pneumococcus appears to have reduced admissions for pneumonia overall, but its impact against severe pneumonia is not clear cut. Pneumococcus may have changed in recent years, shifting toward strains which are not impacted by vaccination.
We are working with UNSW on this multi-centre study in Australian children.We aim to work out how effective vaccination is for preventing pneumonia, and which strains of pneumococcus are responsible. This should help to improve the vaccine program.
