Factors influencing the decision to uptake COVID-19 vaccine based on the Theoretical Domain Framework: A mixed methods study of older adults in Singapore

Completed

Objective

Singapore’s COVID-19 vaccination programme aims to fully vaccinate all who are eligible. Currently, data on take-up rate is promising. Despite the progress, some vaccine hesitancy remains. A decision to vaccinate or not is often complex and beyond individual psychological factors, can be highly influenced by local vaccine policies, social media as well as an individual’s social network.

Informed by the Theoretical Domains Framework (TDF), this study aims to understand the barriers and facilitators toward vaccination.

It will be conducted using a mixed methods design.

Understanding the thinking of Singaporean older adults on vaccination is important as this will allow the tailoring of interventions and campaigns to encourage vaccination especially since COVID-19 booster shots (and possibly yearly COVID-19 vaccination) are needed, particularly as more contagious variants emerge.
