• To determine the best vaccination strategy for early interventions that improve school readiness of Indigenous children and others at high risk of otitis media and hearing loss throughout the first 3 years of life.

Educational and health outcomes of Indigenous children are extremely poor, particularly in remote areas. High rates of ear disease, particularly 'runny ears' and 'glue ear', and hearing loss throughout early childhood contribute to developmental delay. Vaccines to prevent ear disease could be used more effectively.  This project is evaluating a novel combination schedule of two different licenced vaccine formulations to maximise protection and improve ear health, hearing, and school readiness.
