Vaccine found effective against most severe type of pneumonia
Streptococcus pneumoniae (the pneumococcus) is estimated to cause over half of all pneumonia-related deaths in children under five years old.
Researchers have found in a new case study that a pneumococcal vaccine was effective at protecting children in Laos against the most severe type of pneumonia.
The research led by the Murdoch Children's Research Institute (MCRI) and published in The Lancet Regional Health -- Western Pacific, found the PCV13-vaccine reduced hypoxic pneumonia and pneumonia requiring oxygen support by 37 per cent.
MCRI Dr Cattram Nguyen said although pneumococcal vaccines were known to reduce severe cases of childhood pneumonia, no studies from Asia had measured their effectiveness until now.
The study involved 826 children, aged up to five years, admitted to hospital with pneumonia. PCV13 reduced hypoxic pneumonia and pneumonia requiring extra oxygen by 37 per cent.
Dr Nguyen said because pneumonia was a leading cause of childhood deaths in Laos, the PCV13 vaccine had great potential to alleviate this burden of disease on the most vulnerable. Pneumonia that requires oxygen therapy is one of the severest manifestations of pneumonia.
