A Qualitative Comparative Analysis to explore the predictors of individuals' willingness towards vaccination

The emergence of COVID-19 traumatized individuals from all walks of life and while the demand for vaccines increased exponentially, the authorities seem to encounter greater challenges on their road to create herd immunity. Governments initiated numerous campaigns to influence individuals to opt for vaccination and India being a diverse country makes it difficult to understand the motivating factors for getting COVID-19 vaccination. The study aimed to explore the predictors of individuals' willingness to get vaccinated using Qualitative Comparative Analysis (QCA). After screening using the vaccine hesitancy scale, a semi-structured interview was conducted among 30 respondents from India. Crisp Set QCA was utilized to analyse the data which lead to nine conditions. A solution combination of seven conditions showed a consistency of 1 and coverage of 0.6. They included knowledge about vaccines, perceived severity of the COVID-19 virus, family and peer influence, media and health department's influence, a sense of social responsibility, trust in the authorities and vaccine efficacy. This study contributes to the relevance of QCA's use in psychological research, especially to identify predictors of willingness to immunize. The findings of this study would help in designing appropriate interventions to enhance willingness to get vaccinated.
