AIR - Current Data

This page provides a State Summary table of current data showing the percentage of fully immunised children.

Page last updated: 27 October 2017

The following tables provide the latest annualised quarterly report on childhood immunisation coverage for the December 2016, March 2017, June 2017 and September 2017, assessment quarters from the Australian Immunisation Register (AIR).

The data show the proportion of children fully immunised at age 12 months, 24 months and 60 months according to the National Immunisation Program Schedule.

A full description of the methodology used can be found in Communicable Diseases Intelligence 1998;22(3), 36-37.

*From quarter ending 31 December 2013, pneumococcal (dose 3) was included in the definition of fully immunised for the 12-<15 month cohort.

Analysis of data: The rolling annualised percentage of all children 'fully immunised' by 12 months of age for Australia increased marginally from the previous report by 0.1 percent to 93.9%. For individual antigens due by 12 months of age all jurisdictions achieved coverage greater than 93.0%.

**From quarter ending 31 March 2017, DTP dose 4 (given at 18 months) was included in the definition for fully immunised for 24-<27 months.

***From quarter ending 31 December 2014, meningococcal C (given at 12 months), and dose 2 measles, mumps, rubella (MMR) and dose 1 varicella (given as MMRV at 18 months) were included in the definition of fully immunised for the 24-27 month cohort.

The inclusion of these immunisations to the coverage calculation in December 2014 and March 2017 caused a drop in the 24-27 month coverage rates. The more antigens included in the assessment, the higher the likelihood of reduced coverage rates. This usually resolves over time as the changes become more routine.


Analysis of data: The rolling annualised percentage of all children 'fully immunised' by 24 months of age for Australia decreased by 0.2 percent to 90.7%. All jurisdictions, except the ACT and the NT, experienced decreases in fully immunised coverage for this age group. The observed decrease in coverage is because of the change in the definition of fully immunised. This usually resolves over time as the changes become more routine. Coverage for individual antigens due by 24 months of age was 91.0% or above in all jurisdictions.

Analysis of data: The rolling annualised percentage of all children 'fully immunised' by 60 months of age for Australia increased since the previous report by 0.2% to 93.7%. All jurisdictions except the NT experienced small increases in the percentage of children ‘fully immunised’ by 60 months of age. Coverage for individual antigens due by 60 months remained greater than 92.0% in all jurisdictions.
