Summary

This study evaluates the community-based health education program in improving early testing for COVID-19, increasing vaccination acceptability and enhancing emergency preparedness and self-protection measures against COVID-19 in HK. We established a partnership with several local community stakeholders and they will be responsible for recruiting participants and implementing educational programs. Half of the community collaborators will receive the core intervention package, and use it as education material. The other half will be encouraged to self-collect and send health information to the participants.
