A(H3) predominated and, in some countries, co-circulated with A(H1)pdm09 and B/Victoria viruses. No B/Yamagata virus detections were confirmed. Substantial proportions of characterised circulating virus subtypes or lineages differed antigenically from their respective northern hemisphere vaccine components. Appropriate levels of influenza virus characterisations should be maintained until the season end and in future seasons, when surveillance is adapted to integrate SARS-CoV-2.engVoRhttp://creativecommons.org/licenses/by/4.0/EuropeInfluenza virusPandemicSurveillanceVirus characterisationCOVID-19Influenza VaccinesInfluenza, HumanHumansInfluenza A Virus, H3N2 SubtypeInfluenza B virusSARS-CoV-2SeasonsWorld Health OrganizationAtribución 4.0 Internacional354263642715220025510.2807/1560-7917.ES.2022.27.15.22002551560-7917Euro surveillance : bulletin Europeen sur les maladies transmissibles = European communicable disease bulletinopen access
