COVID-19 and influenza vaccine uptake in women with criminal-legal system involvement

Abstract

Objective: Given their vulnerable health status and resource constraints, the perspectives of women with criminal-legal involvement (WCLI) are important but not usually represented in the literature on vaccine interest and vaccine hesitancy. This study aims to examine how the COVID-19 pandemic and vaccine affected the influenza vaccine uptake among WCLI. Methods: A cross-sectional secondary analysis was conducted using data collected from the Tri-City study, which followed WCLI in three U.S. cities from 2019 to 2023. We mapped the distribution of influenza vaccine uptake in 2019-2023 and developed a composite outcome that reflected participants' patterns of Y/N to influenza vaccine, which were categorized into four groups: Influenza Vaccine Supportive, Influenza Vaccine Adaptive, Influenza Vaccine Discontinued, and Influenza Vaccine Resistant. Results: Out of 507 people: 23.7% were Supportive, 8.5% Adaptive, 15.2% Discontinued and 38.3% Resistant. People who received the COVID vaccine had significantly lower odds of being identified as Discontinued (OR = 0.42, 95%CI = 0.20-0.87, p = .020) and Resistant (OR = 0.23, 95%CI = 0.13-0.43, p < .001), compared to the Supportive group. Mistrust toward COVID-19-related information was a significant independent predictor of being Adaptive (OR = 1.59, 95%CI = 1.08-2.35, p = .019), Discontinued (OR = 1.61, 95%CI = 1.15-2.25, p = .006), and Resistant (OR = 1.54, 95%CI = 1.19-2.00, p < .001) relative to Supportive. Conclusions: Vaccine hesitancy poses significant challenges to public health efforts, with apparent dampening effect across vaccines. Public health messaging and clinical interactions informed by best practices in communication tailored to the lived experience of all people, including women with criminal-legal system involvement, will be necessary to inform future interventions aimed at increasing vaccine uptake.
