Abstract

We characterized 7 highly pathogenic avian influenza A(H5N1) viruses isolated from poultry in China during 2009-2012 and found that they belong to clade 2.3.4 but do not fit within the 3 defined subclades. Antigenic drift in subtype H5N1 variants may reduce the efficacy of vaccines designed to control these viruses in poultry.
