NCIRS plays a pre-eminent role in the analysis and reporting of data from the Australian Childhood Immunisation Register (ACIR) and the use of these data for research, surveillance and program evaluation. NCIRS receives de-identified data from the ACIR every 3 months from the Australian Government Department of Human Services.
Some NCIRS reports based on ACIR data are summarised below.
Annual immunisation coverage reports, Australia
Immunisation coverage reports are produced annually to highlight important trends and issues in immunisation coverage in Australia. They provide a detailed summary of vaccination coverage at standard milestone ages, coverage for vaccines not included in standard coverage assessments, timeliness of vaccination, coverage for Indigenous children, analysis of ‘partially immunised’ children, and data for small geographic areas on the prevalence of vaccination objection. These reports also include data on adolescents outside the Australian Childhood Immunisation Register (ACIR) age group from other sources.
The 2014 annual immunisation coverage report is available below along with a summary of key findings and accompanying slideset containing tables and figures from the report.

Annual immunisation coverage reports, New South Wales
Immunisation coverage reports are also produced annually for New South Wales. The 2013 annual NSW immunisation coverage report, available below, documents trends in immunisation coverage in NSW for children, adolescents and the elderly up to 2013. Data from the Australian Childhood Immunisation Register, the NSW School Immunisation Program and the NSW Population Health Survey were used to calculate various measures of population coverage. Greater than 90% coverage has been reached for children at 12, 24 and 60 months of age. Delayed receipt of vaccines is still an issue for Aboriginal children. For adolescents, coverage for the third dose of HPV vaccine for females in the school program was 79% by age 15, an increase of 6 percentage points from 2012 (73%). For males it was 56% by age 15. Pneumococcal vaccination coverage in the elderly remained lower than for influenza.

Trends and patterns in vaccination objection, Australia, 2002–2013
Considerable media and public attention has been focused in recent years on the refusal by some parents to vaccinate their children as recommended by health authorities. Vaccination coverage has often been purported to be declining nationally as a result. This NCIRS study aimed to examine trends in registered vaccination objection and differences in geographic and demographic distribution across Australia, and to assess the contribution of unregistered objection to incomplete vaccination. The study found that the proportion of children affected by registered vaccination objection increased from 1.1% in 2002 to 2.0% in 2013. Children with registered objection were clustered in regional areas, while the proportion was lower among children living in areas in the lowest decile of socio-economic status (1.1%) compared to areas in the highest socio-economic decile (1.9%). The study estimates that 3.3% of children aged 1-6 years are affected by registered or presumptive (unregistered) vaccination objection, which suggests that the overall impact of vaccination objection on vaccination rates has remained largely unchanged since 2001.
