A qualitative analysis of COVID-19 vaccination intent, decision-making, and recommendations to increase uptake among residents and staff in six homeless shelters in Seattle, WA, USA

COVID-19 vaccines mitigate severe disease, yet uptake remains low among people experiencing homelessness (PEH) despite the risk of transmission in congregate settings like homeless shelters. This study evaluated retrospective COVID-19 vaccination intent and decision-making between March 2020-October 2021 to identify modifiable factors to improve vaccine acceptance among PEH. We conducted 31 semi-structured interviews and eight focus group discussions across six homeless shelters in Seattle-King County, Washington. Residents and staff aged >= 18 years were recruited through purposive sampling for interviews and convenience sampling for focus groups. Thematic analysis was conducted. Participants reported that too much contradictory and changing information about COVID-19 vaccines led to confusion. Information deemed trustworthy contributed to individual's knowledge and in some cases changed their vaccination intent. While many intended to get vaccinated without external motivators, others were motivated by incentives and requirements. Despite intention to vaccinate, participants reported barriers to COVID-19 vaccine access including availability of vaccine doses, timely eligibility for vaccination, and availability of appointments. Participants presented recommendations to improve COVID-19 information content and dissemination, access, and use of incentives in shelter settings. Future research should test recommended vaccination strategies rooted in the voices and experiences of PEH to determine feasibility and effectiveness in shelter settings.
