摘要

EFFECTIVE VACCINE COMPOSITION IN PREVENTING OR BETTER INFECTION BY AVIAN INFLUENZA VIRUS; METHOD FOR PREVENTING OR IMPROVING ECLOSION OF INFLUENCE WITH AVIAN INFLUENCE. The invention relates to a vaccine composition that is effective in preventing or ameliorating infection with avian influenza virus. The vaccine contains at least two inactivated strains of avian influenza virus, where the total combined hemagglutinin (HA) is at least about 256 HA / dose of the vaccine composition, and where each strain has at least about 128 strains. NA / dose, and where one of the strains still has the same NA subtype as a provocative virus, and where at least one of the strains has a different NA subtype than the provocative virus.
