Background: Aboriginal children living in remote communities are at high risk of early and persistent otitis media. Streptococcus pneumoniae and non-typeable Haemophilus influenzae (NTHi) are primary pathogens. Vaccines with potential to prevent early OM have not been evaluated in this population. We compared immunogenicity (ELISA and opsonophagocytic activity) of a combination of Synflorix™ (PHiD-CV10, 10 serotypes and protein D of NTHi) and Prevenar13™ (PCV13, 10 serotypes plus 3, 6A, and 19A), with recommended schedules. Methods: This open-label superiority trial randomised (1:1:1) Aboriginal infants at 28 to 38 days of age, to PCV13 (P) at 2-4-6 months (_PPP), PHiD-CV10 (S) at 2-4-6 mont..View full abstract
