Also in Egypt, the number of H5N1 infections in humans is the highest in the world, and low pathogenicity influenza A(H9N2) virus is widespread among poultry and has infected humans (2). Despite extensive vaccination, H5 ...

During the outbreak of HPAI H5N2 in 1994-1995, Mexico applied large-scale vaccination campaign using inactivated homologous H5N2 vaccines [18, 31].

In birds, there are 16 HA and 9 NA subtypes with possible combination of 144 HA-NA subtypes (e.g. H1N1, H5N1, H7N7, H9N2, etc.). According to their pathogenicity in chickens, only some strains of H5 and H7 subtypes are able to produce mass morbidity and mortality and thus are classified as highly pathogenic AIV (HPAIV ...
