The outbreak of bird flu that began in the United States in 2022 among wild birds and poultry has since spread to dairy cattle, at least one pig, a growing number of people — and even cats.

This study illustrated that a single application of a multivalent genetic-matching whole AIV vaccine under laboratory conditions elicits adequate protection against the HPAI challenge, representing 2.2.1.2 and 2.3.4.4b clades. The developed vaccine has the potential to be a vaccine of choice against …

Avian influenza poses substantial risks to animal welfare and public health. The recent surge in highly pathogenic avian influenza (HPAI) outbreaks has led to extensive poultry culling, highlighting the need for early warning systems. Using data on H5 HPAI virus (HPAIV) occurrence from the World Org …

Infections with H5N1, a type of pathogenic avian influenza (HPAI) virus, are spreading among livestock farmers, particularly among dairy cows in the United States.
