The frequent economic losses incurred with H9N2 low pathogenic avian influenza viruses (LPAI) infection have raised serious concerns for the poultry industry. A 1-dose regimen with inactivated H9N2 LPAI vaccine could not prevent vaccinated poultry from becoming infected and from shedding wild viruses. A study was conducted to determine whether a 2-dose regimen of inactivated H9N2 LPAI vaccine could enhance the immunologic response in chickens. Such gel-primed and mineral oil-boosted regimen has produced encouraging results associated with improved immune responses to an H9N2 LPAI. This strategy could be cost effective and helpful for preventing avian influenza virus in the poultry industry.
