Does enhanced educational intervention reduce breakthrough infection and mental health problems via improving acceptance of COVID-19 booster shots in Chinese non-healthcare workers: A randomized controlled trial?

Background: Despite vaccination and booster shots proving more effective than workplace measures in controlling the COVID-19 pandemic, hesitancy towards compulsory booster shots remains. This study aimed to evaluate the effectiveness of an enhanced educational intervention program in improving the acceptance of COVID-19 booster shots and reducing breakthrough infections among non-healthcare workers in Hong Kong.

Methods: In this 9-month randomized controlled trial (RCT), workers were randomly allocated to either the intervention or control group.
