Determinants of COVID 19 Vaccine Uptake Among People with Substance Use Disorder in Türkiye

Aim; The COVID-19 pandemic has highlighted significant socioeconomic and health disparities, particularly for socially vulnerable populations such as individuals with Substance Use Disorder (SUD). Despite the heightened risk of severe COVID-19 outcomes, individuals with SUD demonstrated higher vaccine hesitancy and lower vaccination rates compared to the general population. This study aimed to assess the vaccination status of SUD patients in Türkiye and explore factors influencing vaccine uptake. Method; The cross-sectional study included a sample of individuals diagnosed with SUD, with data on COVID-19 infection and vaccination retrieved from digital health records. Sociodemographic characteristics, paranoid ideation, and vaccine confidence were assessed using structured forms. Results; The findings suggest that vaccine confidence is the primary determinant of vaccination status, while other sociodemographic factors showed no significant relationship with vaccination. Conclusion; These insights underscore the need for tailored public health interventions to boost vaccine confidence, particularly in addressing healthcare distrust and logistical barriers. Further research is recommended to better understand the low vaccine uptake in this high-risk group and develop effective strategies for prevention.
