Avian influenza virus (Avian Influenza Virus, AIV) antigens are diverse, and there is no strong cross-protection among subtypes. Because commonly used anti-avian influenza virus drugs such as amantadine hydrochloride reduce the yield of laying hens, and AIV is prone to drug resistance to it, while ribavirin and virin not only reduce egg production, but are shared by humans and animals. drugs, limiting their clinical application. Since the problem of drug residues has restricted the export of animal-derived food in my ...
