Interim 2017/18 influenza seasonal vaccine effectiveness: combined results from five European studies

Marc Rondy et al. Euro Surveill. 2018 Mar.

Abstract

Between September 2017 and February 2018, influenza A(H1N1)pdm09, A(H3N2) and B viruses (mainly B/Yamagata, not included in 2017/18 trivalent vaccines) co-circulated in Europe. Interim results from five European studies indicate that, in all age groups, 2017/18 influenza vaccine effectiveness was 25 to 52% against any influenza, 55 to 68% against influenza A(H1N1)pdm09, -42 to 7% against influenza A(H3N2) and 36 to 54% against influenza B. 2017/18 influenza vaccine should be promoted where influenza still circulates.

Keywords: Europe; case control study; influenza; influenza vaccination; influenza vaccine effectiveness; multicentre study.
