About these tables

These tables provide the latest annualised quarterly report on childhood immunisation coverage from the Australian Immunisation Register (AIR), which combines the September 2020, December 2020, March 2021 and June 2021 assessment quarters. 

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 is 94.85%.

For individual antigens due by 12 months of age, all states and territories achieved coverage greater than or equal to 94.63%.

  • * 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 months coverage rates. The coverage rate has dropped because the criteria to be assessed as fully immunised now includes more antigens.
  • 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 is 95.18%.

Coverage for individual antigens due by 60 months was greater than or equal to 94.44% in all states and territories.
