There have continued to be modest but concerning declines in vaccination coverage in children and adolescents relative to pre-pandemic peaks, with decreases greater in Indigenous children and adolescents. Evidence suggests that the factors contributing to these ongoing declines are complex and variable but include both vaccine acceptance and access issues. The picture for adult coverage is more mixed, with coverage increasing for 13vPCV, stable for zoster and decreasing for influenza vaccination, though consistently suboptimal across all vaccines. Ongoing monitoring of vaccination coverage, and further exploration of the reasons underpinning these decreases and suboptimal coverage, are needed to inform approaches to address barriers effectively and to increase vaccine uptake and equity of coverage.
