Participatory transferability analysis of vaccination interventions with underserved communities

BACKGROUND: The Horizon 2020 project RIVER-EU will remove health system barriers to childhood vaccination in the migrant community in Greece, the Turkish and Moroccan communities in the Netherlands, the Ukrainian minority in Poland, and the marginalized Roma community in Slovakia. In order to identify transferable vaccination interventions for HPV and MMR, our aim was to establish a collaboration with various stakeholders from these communities. METHODS: For the transferability analysis, we used the participatory action approach (PAR) to stimulate meaningful participation of different key stakeholder groups in discussing evidence-based interventions and the specific contextual conditions of the underserved communities. Based on the PIET-T models, we collaboratively explored characteristics of the populations (P), interventions (I), environments (E) as well as options for intervention transfer (T) to understand transferability (T), need for intervention adaptations or new interventions. RESULTS: Six interventions were pre-selected for decision-making. These addressed elements of involving community members to support vaccination, education in schools, providers’ vaccine communication, and educational videos. All partners co-created knowledge through their expertise: Community members contributed through their experiences with vaccination services, provided valuable arguments for or against interventions, as well as ideas for improvement. Country coordinators in each context were mediators for knowledge-co-creation between all partners involved. Transferability researchers guided the process and analysed the results of discussions through workshops, interviews and focus groups. CONCLUSIONS: Establishing trust between partners was a key issue in all contexts. Participatory transferability analysis required the consideration of a complex interplay between understanding content of interventions, context, and the specific characteristics and contributions of stakeholders.
