Mitigation and Prevention

Practice strategy involves including unhoused peer ambassadors in outreach plans to encourage vaccination against Covid-19 in homeless encampments/shelters. Peer ambassadors were found to be effective in promoting vaccination among their peers. However, some concerns existed around the ethics of exploiting the trust unhoused PAs had with their communities, as well as apathy and frustration towards the academic and bureaucratic nature of the research study.
