Recommended composition of the Northern Hemisphere influenza vaccine for the 2013-14 season

This article lists the influenza vaccines recommended by the World Health Organization for the Northern Hemisphere influenza season for 2013-14.

Page last updated: 20 May 2013

On 21 February 2013, the World Health Organization (WHO) recommended that vaccines for the 2013-14 northern hemisphere influenza season contain the following:

A (H1N1): an A/California/7/2009 - like virus.

A (H3N2): a virus antigenically like the cell-propagated prototype virus A/Victoria/361/2011. It is recommended that A/Texas/50/2012 is used as the A(H3N2) vaccine component because of antigenic changes in earlier A/Victoria/361/2011-like vaccine viruses resulting from adaptation to propagation in eggs.

B: a B/Massachusetts/2/2012 - like virus (Yamagata lineage)

It is recommended that quadrivalent vaccines containing two influenza B viruses contain the above three viruses plus a B/Brisbane/60/2008-like virus (Victoria lineage).
