Dr. Mattie Castiel, Worcester’s commissioner for health and human services, stresses the safety of the COVID-19 vaccine in a video she posted on Twitter.

The Department of Public Health has launched a public awareness campaign to address COVID-19 vaccine hesitancy.

For the Trusted Sources video project, the DPH is asking community leaders to self-record short (one minute) videos promoting trust in the COVID vaccine. Leaders are asked to share the videos via their social media networks using the #TrusttheFacts hashtag.

Campaign participants include former Boston Red Sox slugger David Ortiz (in English and Spanish), Worcester Health and Human Services Commissioner Dr. Mattie Castiel, Boston Mayor Kim Janey, and Suffolk District Attorney Rachel Rollins.

The campaign supplements the state’s “Trust the Facts. Get the Vax” effort.
