Key points
- The influenza season 2014/15 started in Europe in week 50 2014 with influenza A(H3N2) viruses predominating.
- The majority of the A(H3N2) viruses characterised antigenically and/or genetically differ from the northern hemisphere vaccine component which may result in reduced vaccine effectiveness for the season.
- We therefore anticipate that this season may be more severe than the 2013/14 season.
- Treating influenza with antivirals in addition to prevention with vaccination will be important.
