We're very grateful: moral emotions, role models, and trust predict vaccine uptake intent in India

This study investigated determinants of the willingness to get vaccinated in India and examined the relationship between engagement in preventive behaviours and vaccine uptake intent. A large-scale online survey covering aspects of COVID-19 preventive behaviours, vaccination status, moral emotions, trust in others, role models, and socio-demographics was used. A total of 953 Indians participated in the survey between May and June 2021, of which 770 contained valid data on vaccination status. Past preventive health behaviours (PHBs) such as avoiding social gatherings, higher interpersonal trust, and moral emotions were robustly associated with the willingness to take a COVID-19 vaccine. Results also showed that unvaccinated individuals were less likely to follow other PHBs, like wearing a mask; past COVID-19 infection status was associated with similar lower adherence to PHBs. Given the strong associations between positive moral emotions, like gratitude, and vaccine uptake intent (especially in the unvaccinated subsample), targeted communication interventions can boost uptake intent, and subsequently vaccine uptake, in jurisdictions with low vaccination rates.
