Abstract

Supported by NextGenerationEU (no. PE00000007) and EU4Health (VAXaction), the workshop will present a pan-European perspective on vaccine hesitancy and the effectiveness of counteracting interventions, especially when facing potentially pandemic infectious threats. Analysing human responses to epidemics is crucial to improve mathematical disease modelling and develop strategies to monitor behaviours during outbreaks, including assessing levels of vaccine hesitancy. This session will explore the multifaceted issue of vaccine hesitancy, which remains a significant barrier to achieving optimal vaccination coverage and is identified as one of the top threats to global health. By integrating theoretical frameworks with practical applications, the workshop aims to present a comprehensive overview of strategies employed to mitigate hesitancy across various demographics and regions. The first presentation will cover a thorough overview of the strategies employed to counteract vaccine hesitancy, leveraging existing infrastructure, health promotion policies, and educational initiatives. It will also explore the role of digital health tools and regulatory measures, such as health passes and nudging techniques, in enhancing vaccination uptake. Furthermore, the session will cover a systematic review of immunisation information systems (IISs) and the proposal of an innovative unvaccinated registry. This part of the workshop will delve into technological advancements and the integration of behavioural insights, which are essential for enhancing vaccine coverage and informing public health strategies. Another significant aspect of the discussion will be the evolution of vaccine mandates, from their historical roots to their contemporary applications. This discussion will reflect on policy shifts necessitated by emerging public health challenges and the need for adaptable strategies that can respond effectively to fluctuating vaccine coverage and acceptance rates. Panel discussions will feature notable experts such as Prof. Carlo Signorelli, President of the Italian NITAG, and Prof. Maria Ganczak, Vice President of the EUPHA Infectious Diseases Control section. These discussions will provide a comparative analysis of vaccination policies across different European countries, highlighting diverse approaches to mandates and the implementation of public health interventions aimed at combating vaccine hesitancy. By providing a unified approach to understanding and combating vaccine hesitancy, we aim to facilitate a critical exchange of ideas and strategies among experts in the field. It will serve as a dynamic platform for discussing evidence-based interventions tailored to specific population needs, enhancing public health outcomes across Europe. This engaging session promises to offer valuable insights into the complexities of vaccine hesitancy and the collaborative efforts required to address this global health challenge effectively.

Key messages
• Enhanced data collection and analysis are essential to combat vaccine hesitancy, allowing for tailored interventions that address specific community needs and barriers to vaccination.
• Effective strategies against vaccine hesitancy require historical understanding and flexibility to adapt to new challenges, ensuring public health policies are responsive and culturally sensitive.
