Building towards vaccine acceptance: Community co-design framework

Abstract

Abstract Background Vaccine hesitancy is a global public health threat. As the COVID-19 pandemic progressed, vaccines, particularly mRNA vaccines, have reduced overall disease severity and death but population coverage has fallen short and uncertainty about vaccination grown. Miscommunication, neglect of health inequities, failure to address vaccine access and other concerns sufficiently have affected trust between populations and healthcare systems. We built on existing models of increasing vaccine acceptance to develop a more comprehensive explanatory model for testing and evaluation. Methods We reviewed the literature on vaccine hesitancy/acceptance models in English and French from PUBMED, ScienceDirect and Google Scholar. We explored their application using the Irish case study, including the Irish tailored communication model, and used the findings to build our model. Results Previous models had gaps in issues considered, planning and implementation. Many neglected wider determinants or health system responsibilities, treating vaccine acceptance as a one-dimensional issue not a continuum. While the need for vaccination programmes to be redesigned to counter known health inequities, gaps in health literacy, access difficulties, exclusionary practices and mistrust of authorities was recognised, few studies addressed these issues. Our analysis also identified the importance of co-creating delivery models with communities. The resulting model supports prioritisation of communities and individuals in line with need, exposure risk and barriers to immunisation. Conclusions Emergency vaccination programmes require greater depth of shared communication and decision making between populations, practitioners, and policy makers. Our model, which incorporates tailored communication, provides a framework for building vaccine acceptance, widening and welcoming participation in development, design, delivery, and improvement. Key messages • Improving vaccine acceptance requires a whole system approach, addressing issues identified in the literature and in practice to improve the design of immunisation programmes. • To establish an active/robust two-way communication mechanisms which provide rapid feedback between communities and health authorities, to improve programmes and tailor them to meet emerging needs.
