Vaccine composition
WHO recommendations on the compositions of influenza vaccines are based on the available data on the antigenic and genetic characteristics of recently circulating viruses and antibody responses to recent vaccines.
February 2012
In February 2012, the WHO recommended that influenza vaccines in use for the 2012/2013 influenza season (northern hemisphere winter) contain:
- an A/California/7/2009 (H1N1)-like virus
- an A/Victoria/361/2011 (H3N2)-like virus
- a B/Wisconsin/1/2010-like virus
The report is available online and it will be subsequently be published in the Weekly Epidemiological record.
September 2011
In September 2011, the WHO recommended that influenza vaccines in use for the 2012 influenza season (southern hemisphere winter) contain:
- an A/California/7/2009 (H1N1)-like virus
- an A/Perth/16/2009 (H3N2)-like virus
- a B/Brisbane/60/2008-like virus
(WER 2011, 86, 457-468: Weekly Epidemiological Record)
Weekly Epidemiological Record 86, 457-468. Recommended composition of influenza vaccines for use in the 2012 southern hemisphere influenza season.
February 2011
In February 2011, the WHO recommended that influenza vaccines in use for the 2011-2012 influenza season (northern hemisphere winter) contain:
- an A/California/7/2009 (H1N1)-like virus
- an A/Perth/16/2009 (H3N2)-like virus
- a B/Brisbane/60/2008-like virus
(WER 2011, 86, 81-91: Weekly Epidemiological Record)
Weekly Epidemiological Record 86, 81-91 Recommended composition of influenza virus vaccines for use in the 2011-2012 northern hemisphere influenza season.
September 2010
In September 2010, the WHO recommended that influenza vaccines for use in the 2011 influenza season (southern hemisphere winter) contain:
- an A/California/7/2009 (H1N1)-like virus
- an A/Perth/16/2009 (H3N2)-like virus
- a B/Brisbane/60/2008-like virus
(WER 2010, 85, 401-412: Weekly Epidemiological Record)
February 2010
In February 2010, the WHO recommended that influenza vaccines for use in the 2010/2011 influenza season (northern hemisphere winter) contain:
- an A/California/7/2009 (H1N1)-like virus
- an A/Perth/16/2009 (H3N2)-like virus
- a B/Brisbane/60/2008-like virus
(WER 2010, 85, 81-92: Weekly Epidemiological Record)
September 2009
In September 2009, the WHO recommended that influenza vaccines for use in the 2010 influenza season (southern hemisphere winter) contain:
- an A/California/7/2009 (H1N1)-like virus
- an A/Perth/16/2009 (H3N2)-like virus
- a B/Brisbane/60/2008-like virus
(WER 2009, 84, 421-432; Weekly Epidemiological Record)
February 2009
In February 2009, the WHO recommended that influenza vaccines for use in the 2009 - 2010 influenza season (northern hemisphere winter) contain:
- an A/Brisbane/59/2007 (H1N1)-like virus - A/South Dakota/6/2007 (an A/Brisbane/59/2007-like virus) is a current vaccine virus used in live attenuated vaccines
- an A/Brisbane/10/2007 (H3N2)-like virus - A/Brisbane/10/2007 and A/Uruguay/716/2007 (an A/Brisbane/10/2007-like virus) are current vaccine viruses
- a B/Brisbane/60/2008-like virus - B/Brisbane/33/2008 is a B/Brisbane/60/2008-like virus
