Flu Vaccine Composition   Leave a comment

I think that adding individual posts about flu vaccine composition is useful but adds to post burden. So, I have decided to summarise them in one single page. Below are the WHO recommendations for the composition of influenza vaccines, in chronological order (latest one first).
(NH = Northern hemisphere; SH = Southern Hemisphere)

the WHO website for influenza vaccine composition can be found here.

2013-14 NH winter

  • an A/California/7/2009 (H1N1)pdm09-like virus
    A/Christchurch/16/2010 is an A/California/7/2009-like virus

  • an A(H3N2) virus antigenically like the cell-propagated prototype virus A/Victoria/361/2011 (A/Texas/50/2012 is recommended due to antigenic changes in the earlier A/Victoria/361/2011-like vaccine viruses resulting from adaptation to propagation in eggs)
    A/Ohio/2/2012, A/Maryland/2/2012, A/South Australia/30/2012, A/Brisbane/1/2012 and A/Brisbane/6/2012 are A/Victoria/361/2011-like viruses

  • a B/Massachusetts/2/2012-like virus
  • for quadrivalent vaccines: a B/Brisbane/60/2008-like virus
    B/Brisbane/33/2008 is a B/Brisbane/60/2008-like virus

2013 SH

  • an A/California/7/2009 (H1N1)pdm09-like virus
    A/Christchurch/16/2010 is an A/California/7/2009-like virus

  • an A/Victoria/361/2011 (H3N2)-like virus
    A/Ohio/2/2012, A/Maryland/2/2012, A/South Australia/30/2012, A/Brisbane/1/2012 and A/Brisbane/6/2012 are A/Victoria/361/2011-like viruses

  • a B/Wisconsin/1/2010-like virus
    B/Hubei-Wujiagang/158/2009 and B/Texas/6/2011 are B/Wisconsin/1/2010-like viruses

  • for quadrivalent vaccines: a B/Brisbane/60/2008-like virus
    B/Brisbane/33/2008 is a B/Brisbane/60/2008-like virus

2012-2013 NH winter

  • an A/California/7/2009 (H1N1)pdm09-like virus
  • an A/Victoria/361/2011 (H3N2)-like virus

2012 SH winter

  • an A/California/7/2009 (H1N1)pdm09-like virus
  • an A/Perth/16/2009 (H3N2)-like virus
  • a B/Brisbane/60/2008-like virus

2011-2012 NH winter

  • an A/California/7/2009 (H1N1)-like virus
  • an A/Perth/16/2009 (H3N2)-like virus
  • a B/Brisbane/60/2008-like virus

2011 SH winter

  • an A/California/7/2009 (H1N1)-like virus
  • an A/Perth/16/2009 (H3N2)-like virus
    A/Wisconsin/15/2009 and A/Victoria/210/2009 are A/Perth/16/2009-like viruses

  • a B/Brisbane/60/2008-like virus

2010-2011 NH winter

  • an A/California/7/2009 (H1N1)-like virus (the pandemic strain)
  • an A/Perth/16/2009 (H3N2)-like virus or A/Wisconsin/15/2009(H3N2)-like virus
  • a B/Brisbane/60/2008-like virus

2010 SH winter

  • an A/California/7/2009 (H1N1)-like strain (the pandemic strain)
  • an A/Perth/16/2009 (H3N2)-like strain
  • a B/Brisbane/60/2008-like strain

2009-2010 NH winter

  • an A/Brisbane/59/2007 (H1N1)-like strain
