The recent events surrounding the Dengvaxia® controversy contributed to a decrease in vaccine confidence. The role of mass media in vaccine hesitancy was highlighted in this study, supporting previous evidence that vaccine-hesitant parents tend to be more susceptible to media reports. The lack of association between sociodemographic factors and vaccine hesitancy implies that the determinants of vaccine hesitancy can be highly varied depending on context and setting.
