A workshop to co-design messages that may increase uptake of vaccines: A case study.

The present case study describes a co-produced and theoretically informed workshop wherein messages were co-designed to increase the uptake of future COVID-19 vaccines in the United Kingdom. Co-design can enhance the legitimacy and effectiveness of public interventions, but many researchers, service providers, and policymakers may be uncertain where to start. This demonstrative example applies behavioural science and design thinking theory, illustrating how others can integrate theoretically informed co-design into similar and more complex projects efficiently. The workshop brought together members of the public, immunisers, and public health specialists. A narrative analysis was conducted to identify themes related to vaccine hesitancy. The workshop's supporting materials are made available as supplemental materials, which can be modified for future workshops. The discussion encourages additional workshops to be conducted, including diverse members of the public, to co-design novel solutions to improve public health more generally.
