During the last 10 years there have been major advances in influenza surveillance, vaccine production and methods to determine vaccine effectiveness (VE), influenza diagnosis by real-time polymerase chain reaction (PCR), and influenza virology. Most of these have been fostered by the threat of a possible pandemic and the planning efforts devoted to minimising its impact.

The Influenza Monitoring Vaccine Effectiveness in Europe (I-MOVE) network, funded by the European Centre for Disease Prevention and Control (ECDC), has made a substantial contribution to these efforts. Among other activities, it has endorsed,case?control test-negative studies focused on providing VE estimates for specific laboratory-confirmed influenza outcomes, especially medically attended influenza-like illness (ILI) [1-3]. As a result of this initiative, I-MOVE associates have published preliminary mid-season estimates of the VE of the 2010/11 influenza seasonal trivalent vaccine to prevent cases of medically attended ILI laboratory-confirmed for influenza [4,5]: two additional preliminary reports are published in this week?s issue of Eurosurveillance [6,7].
