COVID-19 Vaccine Hesitancy and Uptake Among Vaccinated Population in Malaysia

This study identified the significant COVID-19 vaccine hesitancy and intention to uptake motives and sociodemographic predictors among vaccinated Malaysian adults. A cross-sectional study using a self-administered online questionnaire adapted from the COVID-19 Vaccine Hesitancy Scale and extended based on previous studies was used to solicit data from 698 Malaysians. A theoretical framework comprising Trust, Vaccine Concerns, Unreliable Entities, Uptake Influencers, Brand Influencers, and Brand_Side-effect was used as a guide to assess intention to receive COVID-19 vaccines in the future. Hierarchical linear regressions revealed Trust, Vaccine Concerns, Brand_Side-effect and Uptake Influencers to significantly predict intention to receive vaccines in the future when controlled for sociodemographic correlates. Ethnicity and technology literacy were found to have significant impacts on future vaccine uptake. Age significantly correlated with intention to be vaccinated as well. Underlying motives and sociodemographic correlates were identified for COVID-19 vaccine hesitancy and uptake.
