Using the Tailoring Immunization Programmes guide to improve child immunisation in Umina, New South Wales: we could still do better.

In the Central Coast Local Health District of New South Wales, Australia, childhood immunisation (CI) rates are around 95%, but pockets of underimmunisation exist. Using the World Health Organization's Tailoring Immunization Programmes, we identified areas of potential low vaccine coverage using Australian Immunisation Register (AIR) data (2016-18) and investigated factors that influence CI. Individual and group interviews with carers, community members and service providers (n=52 participants) were conducted. Data were analysed thematically and the themes presented to stakeholders for feedback before finalisation. During 2018, Umina had 218 children at least 1 month overdue for at least one vaccination. Five themes emerged: (1) broader socioeconomic factors may apply pressures that influence CI; (2) parents largely supported immunisation and knew of its benefits to their children and the community; (3) immunisation service providers are committed, experienced and collaborate with community partners; (4) there is potential to increase access to free immunisation services in Umina; and (5) AIR data and reminder systems could be better used to inform service delivery and prompt parents before immunisations are due. This study identified opportunities to improve CI coverage in Umina and new information useful in developing a tailored immunisation strategy. Awareness of the pressures socioeconomic factors may have on families could help plan and deliver supportive primary health care that includes equitable access to immunisation.
