About these tables

These tables provide the latest annualised quarterly report on childhood immunisation coverage for the June 2017, September 2017, December 2017 and March 2018 assessment quarters from the Australian Immunisation Register (AIR)

The data show the proportion of children fully immunised at one, two and five years of age according to the National Immunisation Program Schedule.

A full description of the methodology used can be found in Communicable Diseases Intelligence 1998, volume 22, issue 3 (pages 36 to 37).

One year olds

This data table is for the one year old cohort (12 to less than 15 months old).

Analysis of data: The rolling annualised percentage of all children 'fully immunised' by 12 months of age increased slightly from the previous report to 94.05 per cent. For individual antigens due by 12 months of age, all states and territories achieved coverage greater than 93.5 per cent.

*From quarter ending 31 December 2013, pneumococcal (dose 3) was included in the definition of fully immunised for the 12 to less than 15 months cohort.

Two year olds

This data table is for the two year old cohort (24 to less than 27 months old).

Analysis of data: The rolling annualised percentage of all children 'fully immunised' by 24 months of age remains steady at 90.52 per cent. Four states and territories (Victoria, Queensland, South Australia and the Northern Territory) experienced increases in fully immunised coverage for this age group. The observed decreases 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 per cent or above in all states and territories.

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

The inclusion of these immunisations to the coverage calculation in December 2014 and March 2017 caused a drop in the 24 to 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.

Five year olds

This data table is for the five year old cohort (60 to less than 63 months old).

Analysis of data: The rolling annualised percentage of all children 'fully immunised' by 60 months of age for Australia increased since the previous report to 94.23 per cent. All jurisdictions (except Queensland) 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 per cent in all states and territories.
