Influenza Virus Characterisation reports, season 2017/18

The ECDC Influenza Virus Characterisations Reports are published periodically. The report provides an overview of the technical details of the circulating influenza viruses, such as antigenic and genetic properties, with a reference to the current vaccine strains. It also summaries the developments of the viruses since the last report, as well as the main developments for the ongoing season. The report is of special interest for influenza virologists and epidemiologists interested in the in-depth characterisation of influenza viruses.
