Predictors of COVID-19 vaccine uptake and preferences for service delivery among people who inject drugs accessing a syringe service program

Our findings reiterate the potential of SSPs to increase COVID-19 and other vaccination rates among PWID and provide insight into implementation adaptations to optimize vaccine uptake, including emphasizing the benefit of vaccines in communication efforts, offering compensation, and leveraging the trusted relationship with SSP staff, particularly peer navigators. Together, this evidence reinforces SSPs' unique ability to increase engagement with and utilization of preventative care services among PWID, within and beyond the COVID-19 pandemic.
