The Australian Childhood Immunisation Register-A model for universal immunisation registers?

The Australian Childhood Immunisation Register (ACIR) was established in 1996 as an opt-out register built on the platform of Medicare, the universal national health insurance scheme. Introduction of financial incentives for providers and parents, linked to the ACIR, followed from 1998. Over the subsequent decade, national levels for receipt of all vaccines by 12, 24 and 72 months of age have risen to 91%, 93%, and 88%, respectively. Conscientious objection to immunisation can be registered, with retention of eligibility for incentives. The ACIR has been important in implementation of a range of measures to improve childhood immunisation coverage in Australia. Linkage of a universal childhood immunisation register to national health insurance schemes has potential applicability in a variety of settings internationally.
