With all the buzz about highly pathogenic H5N1 avian influenza (HPAI), we thought it would be useful to review this chapter in veterinary vaccine history. It turns out that Asian countries have deployed vaccines since 1995, and China started vaccinating poultry in 2004. In the same year, the US had its first outbreak of H5N2 avian influenza in over twenty years.

“On 17 February 2004, the state of Texas reported the detection of a type A influenza virus from chickens. The mild clinical signs observed in the affected flock were consistent with an infection caused by a low pathogenicity AIV. However, the presence of multiple basic amino acids at the HA cleavage site, which was identical to the amino acid sequence in the highly pathogenic A/chicken/Scotland/59 (H5N1) virus, required that the United States Department of Agriculture (USDA) National Veterinary Services Laboratories report that the A/chicken/Texas/298313/04 (TX/04) (H5N2) isolate was classified as a highly pathogenic AIV on 23 February 2004. However, on 1 March 2004, National Veterinary Services Laboratories announced the results of the chicken pathogenicity test that showed the virus as being avirulent for chickens; the chickens remained healthy throughout the 10-day observation period.”
