Influenza – Monitoring Vaccine Effectiveness in Europe (I-MOVE)

I-MOVE (Measuring of Influenza Vaccine Effectiveness in Europe) is a network of 20 European countries measuring influenza vaccine effectiveness (VE) since 2008. Eleven study sites in Europe measure VE in early and late season using cohort,case control and case coverage studies. Among them a multicentre case control study is gathering data from 8 countries using the same test negative design protocol. Each year early and final VE estimates are made available to EU member states,WHO,ECDC,EC and EMA. Once a year an international workshop gathers specialists from EU,USA,Canada and Australia to review seasonal results and discuss methods used.
