In the Wake of Scandals: How Media Use and Social Trust Influence Risk Perception and Vaccination Intention among Chinese Parents.

Recently, repeated childhood vaccine scandals shook public confidence in vaccine safety in China. This study explores whether media attention, online discussion, and social trust influence Chinese parents' risk perception and vaccination intention. Based on data from a Qualtrics panel ( = 354), results indicate that media attention is positively related to social trust and online discussion is positively related to perceived benefits. Additionally, social trust is negatively associated with perceived risk but positively associated with perceived benefits. Social trust is also positively related to general vaccination intention and intention to get domestic vaccines. Further, social trust mediates the relationship between media attention/online discussion and risk perception. Lastly, parents with higher risk perception are less likely to get domestic vaccines, but more likely to get imported vaccines. Perceived benefits also influence vaccination intention.
