The purpose of this study was to look at the validity of parent-reported influenza vaccination and provider reporting to the Australian Immunisation Register (AIR) in children with high-risk medical conditions (SRMC). From September 2015 to February 2016, a cross-sectional survey was conducted with parents of children with SRMC aged 6 months to 18 years who were visiting the Women’s and Children’s Hospital in Adelaide, Australia. Data from 7-year-old children was collected to evaluate provider-AIR reporting. The influenza vaccination status of the kid was obtained from the child’s parent, immunisation provider, and AIR. The Kappa index was used to determine concordance, and the sensitivity, specificity, positive predictive value, and negative predictive value were computed. For 2014 and 2015, 389 and 395 parent-provider influenza vaccination data were available, respectively. Discordance was greater in 2014, owing mostly to parental misreporting of immunisation. When compared to moms, fathers overreported. There were 241 records of provider-AIR influenza vaccinations. The AIR’s sensitivity to reflect a child’s influenza immunisation status was poor.

Parental report overestimates verified influenza vaccination status and is influenced by time and the child’s connection to the parent. The AIR received reports on just one-third of all influenza vaccines. It is important to have up-to-date, accurate data in order to allow immunisation and evaluate programme coverage.
