          Impact of COVID-19 on School-based Vaccination Programs

          2023

          This NCIRS evaluation has found that overall, pandemic impacts on vaccination uptake in adolescents were relatively limited in Australia compared to other countries; however, the number of adolescent vaccinations given in 2020 and 2021 was lower than in 2019.

          Key findings - Annual Immunisation Coverage Report 2021

          2022

          This summary report presents key findings from the Annual Immunisation Coverage Report 2021 which focused on changes in immunisation coverage among all children aged <5 years, adolescents and adults between 2020 and 2021. The summary report also shows vaccination coverage among Aboriginal and Torres Strait Islander children and the impact of remoteness and socioeconomic status on vaccination coverage rates. This is the first report in the series to comprehensively document the impact of the COVID-19 pandemic and associated public health response measures on vaccination coverage.

          Annual Immunisation Coverage Report 2021

          2022

          The Annual Immunisation Coverage Report 2021, released by the National Centre of Immunisation Research and Surveillance (NCIRS), examines Australian Immunisation Register (AIR) data for children, adolescents and adults and is the first to comprehensively document the impact of the COVID-19 pandemic and associated public health response measures on vaccination coverage. Vaccination coverage in children in Australia remained relatively high overall in 2021, despite the major disruptions associated with the COVID-19 pandemic, however pandemic impacts on coverage were greater in some areas, particularly remote areas with a high proportion of Aboriginal and Torres Strait Islander people, the report has found.

          Paediatric SARS-CoV-2 serosurvey 2022, Australia: Summary report

          2022

          The Paediatric Active Enhanced Disease Surveillance (PAEDS) Network and the National Centre for Immunisation Research and Surveillance (NCIRS) conducted a study to estimate the seroprevalence of SARS-CoV-2 antibodies in children and adolescents aged 0–19 years until August 2022. The study findings suggest there have been high rates of infection in children and adolescents of all ages across Australia, including those whose parents had not suspected infection and in vaccinated children. However, hospitalisation rates are lower, indicating children, especially those who are vaccinated, rarely experience severe disease.

          Summary of National Surveillance Data on Vaccine Preventable Diseases in Australia, 2016-2018

          2022

          This summary report on vaccine preventable diseases (VPDs) in Australia brings together the three most important national sources of routinely collected data on VPDs – notifications, hospitalisations and deaths – for all age groups for the three-year period 1 January 2016 to 31 December 2018. This report, prepared by NCIRS, has been published as a supplement in the Communicable Diseases Intelligence journal. NCIRS has published six of these reports since 2000. These reports serve as a national resource to support surveillance and control of VPDs in Australia, particularly VPDs targeted by the National Immunisation Program.

          Summary report - Increasing COVID-19 vaccine uptake in children aged 5-11 years: behavioural insights from the field

          2022

          This report summarises the reflections from an online forum convened by COSSI and NCIRS, and supported by the Australian Government Department of Health, on 3 March 2022. The forum, titled ‘Increasing COVID-19 vaccine uptake among children aged 5-11 years: behavioural insights from the field’ aimed to identify the drivers of COVID-19 vaccination in children aged 5-11 years and discuss strategies for increasing coverage.

          Annual Immunisation Coverage Report 2020

          2021

          The Annual Immunisation Coverage Report 2020 is the 14th in the series, and the first to present adolescent and adult vaccination data from the Australian Immunisation Register, in addition to childhood vaccination data. The report shows 'fully vaccinated' coverage increased at all three age milestones in all children and Aboriginal and Torres Strait Islander children between 2019 and 2020. Human papillomavirus (HPV) vaccination coverage in adolescents by 15 years of age continued to increase, as did recorded influenza vaccination coverage in adults. However, recorded zoster vaccination coverage among older adults remained low. The report also shows persisting issues with timeliness of childhood vaccination, particularly for Aboriginal and Torres Strait Islander and socioeconomically disadvantaged children, and those living in remote areas.
