Annual Immunisation Coverage Report 2022

Vaccination coverage in children and adolescents decreased modestly in 2022, reflecting impacts of the COVID-19 pandemic, but remained relatively high in global terms. The decrease in coverage was greater in Indigenous children and adolescents, with timeliness of vaccination an ongoing issue exacerbated by the pandemic. While adult coverage increased in 2022 - likely, in part, due to the introduction of mandatory reporting to AIR resulting in more accurate estimates - it remains suboptimal. Limited evidence suggests the lower coverage in children and adolescents is due to a combination of acceptance and access factors. Particularly given the evidence that these modest declines in coverage have continued into the first half of 2023, further exploration is needed to better understand these factors and to inform approaches to effectively address barriers and increase vaccine uptake.
