With the winter at the door, influenza epidemics are a problem to deal with. Every year they cause significant morbidity and mortality throughout Europe, especially in high-risk groups such as older people, individuals with chronic diseases, pregnant women and small children. In most of EU/EEA countries, uptake of seasonal influenza vaccination for these more endangered groups fall below the coverage threshold that the European Council of Ministers set at 75%.
