Mistrust in public health institutions is a stronger predictor of vaccine hesitancy and uptake than Trust in Trump

STUDY GOAL: This study examines the sources of COVID-19 vaccine hesitancy and refusal in Americans by decomposing different forms of government trust/mistrust including trust in Trump and mistrust in public health institutions. METHODS: Using linear panel regression models with data from 5,446 US adults (37,761 responses) from the Understanding America Survey, the likelihoods of vaccine hesitancy, uptake, and trust in various information sources were examined. RESULTS AND CONCLUSION: We find that the likelihoods of hesitancy and having negative perceptions of COVID-19 vaccines were consistently much higher among PHI mistrusters, showing even a stronger hesitancy than Trump trusters. This tendency has persisted over time, resulting in only 49% of PHI mistrusters having been vaccinated in the most recent survey wave. However, a large portion of PHI mistrusters still trusted physicians, family, and friends. These findings suggest that mistrust in PHIs is a salient predictor of vaccine hesitancy and reduced uptake on its own, which is compounded by trust in Trump.
