Description:Help on this term

The proportion of 1-, 2- and 5-year-olds who have been assessed as fully immunised according to information recorded in the Australian Immunisation Register.

Rationale:Help on this term

Immunisation is highly effective in reducing morbidity and mortality caused by vaccine-preventable diseases such as measles, meningococcal disease and poliomyelitis. Vaccinations are an effective strategy for reducing disease disparities between population groups.

Methodology:Help on this term

A full description of the methodology used can be found in Methodology for measuring Australia's childhood immunisation coverage (O'Brien et al. 1998).

For each age it is assumed that earlier vaccinations in the series have been given.

A change in the definition of fully immunised for 2 year olds occurred from the quarter ending 31 December 2014 when meningococcal C vaccination (given at 12 months), dose 2 measles, mumps, rubella (MMR), and dose 1 varicella vaccination were included in the definition of 'fully immunised'. A second change for this age group occurred from the quarter ending 31 March 2017 when dose 4 diphtheria, tetanus, pertussis (DTP) was included in the definition of ‘fully immunised’. The inclusion of these additional vaccines caused decreases in the reported immunisation coverage rates at 2 years of age.
