8.D. Scientific session: Equitable Immunization: Leveraging Prisons for Vaccination Equity in Europe

Abstract Addressing low vaccine coverage is a pressing public health concern in Europe, where pockets of unvaccinated individuals persist despite ongoing efforts. The European region sees an estimated 1.4 million individuals detained on any given day, with a significantly higher number passing through prisons annually due to high turnover rates. Those experiencing incarceration often come from socially marginalized and disadvantaged groups, facing a multitude of health challenges including non-communicable diseases, infectious diseases, mental illness, cognitive disabilities, and substance dependence. Despite their elevated health needs, individuals in prison frequently encounter barriers to accessing healthcare services, including preventive measures such as vaccination. Available but limited data suggest that individuals entering the prison system are often under-immunized, particularly against Hepatitis B Virus (HBV), influenza, measles, mumps, rubella (MMR), and pneumococci. Unfortunately, vaccination services within prisons are often insufficient, typically being provided according to national schedules or in response to outbreaks of vaccine-preventable diseases (VPDs). It’s crucial to distinguish between the availability of vaccination services and actual coverage, as the modalities of vaccination offerings vary across the region. While individuals in prison are recognized as a target group for HBV vaccination, the methods of offering vaccines may differ based on factors such as age or risk group. Nevertheless, systematic implementation of HBV vaccination in prisons has shown clear benefits for both incarcerated individuals and the wider community. Given the significance of vaccinations in preventing diseases like HBV and human papillomavirus (HPV), which are linked to cancer, initiatives like the Europe Beating Cancer Plan and the European Council Recommendation on vaccine-preventable cancer emphasize their importance. Prisons can serve as a strategic point for delivering comprehensive healthcare and vaccination services to incarcerated individuals, yet routine data on vaccination coverage at entry and uptake during incarceration are often lacking, hindering effective health planning. To address this public health challenge, the ‘Reaching the hard-to-reach: Increasing access and vaccine uptake among prison population in Europe’ (RISE-Vac) project consortium has been formed. This collaborative effort brings together diverse expertise and established networks in the field of prison health, reflecting the varied epidemiological and structural landscapes across Europe. The objective of this workshop is to showcase recent research findings, evidence-based practices, and policy recommendations aimed at enhancing vaccination equity in the European region. By sharing insights and best practices, we aim to bolster efforts to improve vaccine access and uptake among incarcerated populations, ultimately contributing to broader public health goals. Key messages • Prison health is public health: vaccination services in prison are essential to achieve immunization targets in Europe. • Maximizing inter-sectoral collaboration is crucial for bridging the gap in vaccination access and uptake among people living in prison in Europe.
