About the data
These data were sourced from the Australian Immunisation Register (AIR), which is administered by the Australian Government Department of Human Services (Medicare). The AIR is estimated to cover 99% of children in Australia. The AIR may underestimate coverage due to incomplete submission of immunisation records or the inclusion of children who no longer reside in an area but have not been updated on the register.
The data reported are for children aged 1, 2 and 5 years for the period 1 April 2015 to 31 March 2016, assessed at 30 June 2016. Data were supplied on 2 March 2017.
See the Technical Note for further information.
Changes to the Australian Immunisation Register
The Australian Immunisation Register (AIR) is a national register that records details of vaccinations given to individuals of all ages who live in Australia. The AIR captures all the National Immunisation Program (NIP) vaccines, and most privately purchased vaccines, given to people of all ages.2
The Register was established in 1996 as the Australian Childhood Immunisation Register (ACIR). Following its expansion in 2016 to include individuals of all ages, its name was revised to the Australian Immunisation Register.
