Recommendations issued for 2011/2012 seasonal flu vaccine composition
The European Medicines Agency has issued the European Union (EU) recommendations for the influenza virus strains that should be included in flu vaccines this year.
Vaccines for the 2011/2012 season should contain three virus strains:
- an A/California/7/2009 (H1N1)-like virus;
- an A/Perth/16/2009 (H3N2)-like virus;
- a B/Brisbane/60/2008-like virus.
The EU recommendation was issued by the Biologics Working Party's Ad-hoc Influenza Working Group on the basis of observations by the World Health Organization (WHO). The Agency's Committee for Medicinal Products for Human Use adopted the recommendation on 17 March 2011.
