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.
