Co-designing an intervention to improve the childhood catch-up vaccination process for migrant parents in Australia.

Background: Catch-up vaccination is a personalised process through which children with missing recommended vaccinations or incomplete vaccination records are brought up to date with the Australian vaccination schedule. Navigating childhood catch-up vaccination can be difficult for migrant parents with inadequate health system knowledge and competing priorities during settlement. This study aimed to understand the experiences of migrant parents with childhood catch-up vaccination and co-design an intervention to improve the process.
