This 10th annual immunisation coverage report shows data for the calendar year 2016 derived from the Australian Immunisation Register (AIR) and the National Human Papillomavirus (HPV) Vaccination Program Register. After a decade of being largely stable at around 90%, ‘fully immunised’ coverage at the 12-month assessment age increased in 2016 to reach 93.7% for the age assessment quarterly data point in December 2016, similar to the 93.4% for the age assessment quarterly data point in December 2016 for 60 months of age.
Implementation of the No Jab No Pay policy may have contributed to these increases. While ‘fully immunised’ coverage at the 24-month age assessment milestone decreased marginally from 90.8%, in December 2015, to 89.6% for the age assessment quarterly data point in December 2016, this was likely due to the assessment algorithm being amended in December 2016 to include 4 doses of DTPa vaccine instead of 3, following reintroduction of the 18-month booster dose. Among Indigenous children, the gap in coverage assessed at 12 months of age decreased 4-fold, from 6.7 percentage points in March 2013 to only 1.7 percentage points lower than non-Indigenous children in December 2016.
