Lessons Learned in Implementing COVID-19 Vaccine “Ask Me Anything” Sessions in Massachusetts County Jails.

How to…	Lessons Learned
Increase attendance	Q&A sessions should be held in housing units rather than common areas in the jail to allow for a gradual increase in participation and attendance
Increase attendee engagement	Session leaders should disclose their jail affiliation (or lack thereof) at the start of the session, briefly provide information about the vaccine before taking questions from attendees, and minimize distractions in the room.
Build trust	Organizers should proactively recruit session leaders with existing ties to the detained population as well as Black, Latinx, and Spanish-speaking session leaders. Session leaders should initiate an explicit discussion around systemic racism, medical abuse, and individuals’ agency in the vaccination decision process.
Overcome structural barriers to vaccination	Session leaders should work with jail staff before Q&A sessions to clarify the mechanism and timeline of requesting and receiving the vaccine at the jail and ensure that a simple mechanism to request vaccination is available at each session.
