WHO vaccine recommendations for 2010-2011 northern hemisphere influenza season

Based on available epidemiological and virological data* provided to WHO between September 2009 and February 2010, WHO has announced the recommended viruses for use in the influenza vaccine for the 2010-2011 northern hemisphere influenza season. The three recommended viruses are:
•an A/California/7/2009 (H1N1)-like virus;
•an A/Perth/16/2009 (H3N2)-like virus; and
•a B/Brisbane/60/2008-like virus.

Human influenza viruses evolve continuously and, consequently, influenza vaccines are updated every year to contain representative circulating viruses. WHO recommendations are offered as a guide to national public health authorities and vaccine manufacturers, to help them use appropriate viruses for the upcoming season.

*for data from the European Region, please consult
* A/Wisconsin/15/2009 is an A/Perth/16/2009 (H3N2)-like virus and is a 2010 southern hemisphere vaccine virus.
