How Misinformation and Rebuttals in Online Comments Affect People’s Intention to Receive COVID-19 Vaccines: The Roles of Psychological Reactance and Misperceptions

Abstract

This study investigated how exposure to negative and misleading online comments about the COVID-19 vaccination persuasive messages and the ensuing corrective rebuttals of these comments affected people’s attitudes and intentions regarding vaccination. An online experiment was performed with 344 adults in the United States. The results showed that rebuttals by the Centers for Disease Control and Prevention, rather than those by social media users, indirectly increased people’s willingness to receive the vaccine by reducing their psychological reactance to persuasive messages and their belief in the misinformation contained in the comments. Rebuttals by social media users became more effective in reducing reactance when people initially had stronger pro-vaccination attitudes.
