Predictors of COVID-19 vaccine uptake and preferences for service delivery among people who inject drugs accessing a syringe service program.
Article in Harm reduction journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionDespite being disproportionately affected by the COVID-19 pandemic, people who inject drugs (PWID) have markedly lower and more variable rates of COVID-19 vaccine uptake-ranging from 10% to 81%-compared to 79% of all US adults. Multiple implementation adaptations have been proposed to address this gap, including offering the vaccines at syringe service programs (SSPs). To inform their implementation at an SSP in Miami, Florida, this study aimed to identify predictors of COVID-19 vaccine uptake and preferences for service delivery among PWID in our context.
methodsBetween June 2022 and July 2023, we administered a cross-sectional survey based on the Health Belief Model with PWID accessing services at an SSP in Miami, FL (n = 135). Bivariate analysis was used to identify factors associated with COVID-19 vaccination status (vaccinated vs. not vaccinated).
resultsOnly 65% of participants had received at least one dose of the COVID-19 vaccine series. Factors associated with COVID-19 vaccination included older age (42 vs. 38 years, p = 0.0287), requiring medical care for previous COVID-19 infections (p = 0.0173), being confident in the US healthcare system (p = 0.0023), and not believing multiple COVID-19 misconceptions (p < 0.05). Among the Health Belief Model domains, perceived benefit, self-efficacy, and one cue to action item were significantly associated with COVID-19 vaccination status: vaccinated participants were more likely to believe in the vaccines' benefits (p = 0.0045-0.0213), report it was easy to get vaccinated (p = 0.0159), and know where to obtain accurate vaccine information (p = 0.0477). Most participants (86%) preferred to receive the COVID-19 vaccine at the SSP, and suggestions for increasing uptake included offering compensation, utilizing peer outreach systems, providing information and reminders, and allowing for accelerated vaccination schedules. DISCUSSION: 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.
