Technical meeting
(Warsaw, May 2025)

Advancing vaccination strategies for older adults:
insights into epidemiology, immunity and implementation
Meeting Objectives
- Clarify the definition of older adults in the context of vaccination by considering factors such as chronological age, comorbidities, and biological markers like immunosenescence and frailty.
- Review and discuss vaccines and vaccination programs targeting older adults across Europe.
- Address the unique challenges and opportunities in conducting vaccination studies, and especially clinical trials, with older adults.
- Explore the mechanisms and factors affecting the efficacy, effectiveness, safety and durability (including boosters) of vaccine responses in older adults and discuss strategies (like adjuvants and higher doses) to enhance immune responses. Discuss specific characteristics of different vaccines for older adults.
- Discuss implementation of vaccination in older adults at the policymakers, organizational and population levels. Identify strategies, including best practices and successes, to increase vaccination coverage in both community and other care settings, and address communication and logistical challenges to ensure program sustainability and equity.
Intended impact
The population in Europe is ageing rapidly, with the proportion of older adults increasing significantly. As a result, the need to protect this demographic group through tailored vaccination efforts has become more urgent within lifelong immunization programs across Europe. This meeting seeks to provide essential insights and strategies to improve vaccine effectiveness, immunity durability, and uptake among older adults. By gathering experts in immunology, vaccine development, geriatrics and public health, the meeting will address the unique challenges faced by older adults, such as frailty, comorbidities, and immunosenescence. The discussions will support National Immunization Programs by sharing the latest information and best practices to boost vaccination coverage, customize strategies, and ensure sustained protection against vaccine-preventable diseases for this growing segment of the population.
Target Audience
- Public health experts, policy makers, healthcare professionals, academics with expertise/ interest in the vaccination of older adults
- AIB advisors and observers
