 The study used an extended protection motivation theory, PMT, with a trust component to identify predictors of vaccine hesitancy among Chinese residents aged 18 and over. Self-efficacy was the strongest predictor while response efficacy had a negative effect on vaccine hesitancy. Vaccine hesitancy had a negative effect on vaccination behavior, but the predictability of vaccine hesitancy on vaccination behavior is limited.
