European decision-maker perspective with regard to influenza prevention policies.

Influenza is a public health priority in Europe. The impact of influenza pandemics on public health is very high, but seasonal influenza also constitutes an important burden in terms of hospitalisation and excess deaths. Influenza vaccination is a fundamental pillar of disease prevention. In the absence of a clear decision-making process for vaccination policies, EU institutions have, in recent years, fostered collaboration among Member States. Such collaboration was closer during the 2009 pandemic, which constituted a clear cross-border threat to EU citizens' health. The EU institutions have been supporting national vaccination programmes by providing evidence of the effectiveness and safety of influenza vaccination. Decision 1082/2013 was a major step toward EU collaboration, in that it highlighted the role of pandemic vaccination in the field of preparedness and emergency response, in which concerted action is clearly valuable.
