Summary
Aboriginal children experience the highest rates of acute and chronic ear infections in the world, with resultant permanent ear damage, hearing loss and educational disadvantage. These infections are mainly bacterial, and Streptococcus pneumoniae (pneumococcus) is the predominant pathogen. Pneumococcal colonisation and infection begins within days of birth, many months before any potential immunological protection from infant pneumococcal conjugate vaccine may be expected.

These infections are mainly bacterial, and Streptococcus pneumoniae (pneumococcus) is the predominant pathogen. Pneumococcal colonisation and infection begins within days of birth, many months before any potential immunological protection from infant pneumococcal conjugate vaccine may be expected. New strategies are needed to eliminate, or at least delay, this early-onset pneumococcal colonisation. One such strategy is the administration to the mother of pneumococcal vaccine, which may protect the newborn infant by leading to higher titres of transplacental or breast milk pneumococcal antibodies and-or by reducing carriage (and transmission to the infant) of maternal pneumococci. Previous small studies using this strategy have been encouraging, but there have been no studies properly evaluating carriage or disease endpoints in infants. The polysaccharide pneumococcal vaccine is currently recommended for all Aboriginal and Torres Islander persons aged 15 years or more in the Northern Territory but uptake of the vaccine has been poor. We propose to conduct a pilot study to determine if maternal immunisation with this vaccine, either in the third trimester of pregancy of immediately following delivery, can reduce pneumococcal carriage and the prevalence of middle ear disease among Aboriginal infants at seven months of age. We aim to recruit 210 Aboriginal women who have uncomplicated pregnancies from Darwin and remote communities in the Top End of the Northern Territory. Each subject and their infant offspring will be followed-up after vaccination and at birth, one , two and seven months after birth.Read moreRead less

This project aims to minimise incorrect use of child restraints, which triple the risk of injury to children in car crashes. One in two children travelling in cars are incorrectly restrained. Using naturalistic and epidemiological studies, this project will characterise child restraint design features that minimise errors related to the real world interaction between restraint design, parents and children, and determine the effectiveness of using optimally designed restraints. This research will help child restraint manufacturers to improve their products and design better child restraint systems, that reduce injury to children in crashes.Read moreRead less
