5.I. Scientific session: Epidemiological insights into vaccine hesitancy in Europe: building bridges and overcoming barriers

Abstract

Abstract Vaccine hesitancy remains a pivotal challenge in public health, undermining immunization efforts and the containment of infectious diseases across Europe. This scientific session aims to dissect the complex nature of vaccine hesitancy, uncovering epidemiological trends and barriers to vaccine acceptance, particularly in diverse demographic contexts. The objective is to facilitate a comprehensive understanding among public health stakeholders and to foster actionable strategies through enriched dialogue and interaction. This session will delve into recent studies and projects that highlight the variability of vaccine hesitancy within Europe. First, an exploration of COVID-19 vaccine acceptance will reveal how sociodemographic factors influence vaccine-related behaviors across 20 European nations. This will be complemented by an analysis of targeted interventions designed to enhance vaccine uptake among migrant populations, drawing lessons from the RIVER-EU project. Additionally, a focus on national efforts to combat measles vaccine hesitancy will provide a case study on the challenges and successes in altering public health narratives. Based on the feedback received on last year’s session, the format is intended not only to provide a platform to present empirical evidence and insights but also to encourage a participatory environment where attendees can exchange ideas and propose innovative solutions. For this reason, the session will engage the audience through an interactive discussion period at the end of each of the three presentations, stimulating thought-provoking dialogues that could lead to effective and innovative public health practices. Fostering international and interdisciplinary collaboration in the field of vaccine hesitancy is key for continued monitoring and reporting on the vaccine hesitancy phenomenon and inspiring actionable solutions. Key messages • Sociodemographic factors are associated with vaccine hesitancy across Europe indicating the potential for targeted strategies. • A platform to share insights and inspire actionable public health solutions to combat vaccine hesitancy amomg European public health professionals is needed.
