Improvements in immunisation rates for 5 year old children
The following information focuses on immunisation rates for 5 year old children, as this is the age when all routine childhood immunisations in the Schedule are expected to be complete (Figure 2).
Measuring immunisation rates over time is important to determine if rates are improving as a result of efforts at the national, state and local levels.
Various initiatives have helped improve childhood immunisation rates. These include new laws requiring children to be immunised to enrol in child care or for parents to receive government rebates, as well as state and territory government programs and local action by healthcare professionals. Public reporting of immunisation rates at the local level may also encourage improvements in the percentage of children fully immunised.
Nationally, the percentage of fully immunised 5 year olds has steadily improved from 90.0% in 2011–12 to 92.9% in 2015–16.
Primary Health Network areas
Similarly, rates have improved amongst PHN areas. Immunisation rates for 5 year olds in all 31 PHN areas improved between 2012–13 and 2015–16. In 2015–16, for the first time, all 31 PHN areas had fully immunised rates over 90%, compared with 25 of the 31 PHN areas in 2012–13 (Figure 4).

What does fully immunised at 5 years mean?

It is assumed that all previous vaccinations were received.
