Influenza is a disease of public health importance due to the substantial seasonal morbidity and mortality and the high pandemic potential of its aetiologic agents, influenza viruses.
The aim of this survey was to review the expertise, capabilities and capacities for detection and characterisation of avian and other zoonotic influenza viruses in national influenza reference laboratories in the European Union/European Economic Area (EU/EEA), in members of the European Reference Laboratories for influenza (ERLINet), and in EU Enlargement policy countries.
This report presents pooled COVID-19 vaccine effectiveness (VE) estimates for the first, second and third booster doses, against hospitalisation due to COVID-19 and COVID-19 related deaths in resident populations ≥50 years of age, living in the community.
