Study population: Young people aged 15-24 years of all genders who have been referred to the Young People's Health Service immunisation nurse will be included. They have accessed a homeless youth service, refuge, or flexible learning centre in Melbourne, Australia. The study will include those who were referred between 19th February 2019 to 19th July 2020.

Brief summary: This retrospective audit will investigate if young people who are homeless or at risk of homelessness in Melbourne were up-to-date with routine childhood and adolescent vaccines on first encounter with a nurse-led primary health clinic (the Young People's Health Service), and if they commenced and completed immunisation catch-up plans following referral to the Young People's Health Service immunisation nurse.

The purpose of the proposed study is to establish baseline immunisation coverage within the targeted population, then to explore the impact of an immunisation nurse role on immunisation coverage in a population of young people aged 15-24 years who are experiencing or at risk of homelessness.

The Young People's Health Service is a program of the Royal Children's Hospital Department of Adolescent Medicine. The data collected will be sourced solely from the Royal Children's Hospital Electronic Medical Records.
