Where are Europeans most and least likely to get the flu vaccine?

As flu season begins in Europe, vaccination rates remain “sub-optimal” in many countries, new health data shows.

The flu season usually runs from mid-November to late May, and last year’s (2024-2025) was particularly fierce. Up to one in five Europeans is infected with influenza every winter, and it is associated with about 27,600 deaths annually across the European Union.
