In the EU, one vaccine is authorised in chickens but is not fully efficacious to stop transmission, highlighting the need for vaccines tailored to diverse poultry species and production types.
10 paź 2023 · The European Union (EU) has experienced an epidemic A widespread occurrence of an infectious disease in a community at a particular time of highly pathogenic avian influenza (HPAI) in wild and domestic birds in recent years.
