The European Society of Medicine is launching this policy framework to address a growing threat to public health. In the face of a persistent decline in vaccine confidence, Europe confronts a critical juncture in its vaccination strategy. Despite the availability of effective vaccines, undervaccination remains a pressing issue, with significant implications for community health and safety.

In several European countries, fewer than 40% of people agree that “vaccines are important, safe, effective, and compatible with your beliefs.” In multiple places this has already lead to vaccination levels below the threshold for herd immunity, and localized outbreaks which are at risk of spreading.

Europe must unite in its efforts to address undervaccination. The stakes are high, and the time to act is now. We are calling upon the medical community to participate in this initiative and submit research which strengthens its objectives.
