According to the U.S. Department of Agriculture (USDA), there are several licensed vaccines for avianinfluenza in poultry, but their use has not been authorized during the ongoing outbreak.
Avianfluvaccines are mostly administered to birds in countries where the flu is endemic and that have minimal poultry trade, such as Egypt, Indonesia, Mexico, and most recently, France.
vaccines offer great potential to mitigate a future pandemic. Influenza A(H5N1) is classified as a highly pathogenic avianinfluenza virus that predominately affects wild birds and poultry.
