About Infectious Bursal Disease

Infectious bursal disease (IBD) is a widespread immunosuppressive illness of young chickens that is linked to increased mortality, reduced flock uniformity and higher rates of processing rejects. Chickens infected with IBD also face a much higher susceptibility to other poultry diseases. Symptoms of the clinical disease can include depression, watery diarrhea, ruffled feathers and dehydration.

IBD is highly contagious and there are no medications available to treat it. However, IBD can be controlled through vaccination programs – including subcutaneous application for layers, breeder flocks and broilers to increase early-life protection by maternal (passive) immunity, followed by in ovo vaccination to extend protection through active immunity.




Innovax®-ILT-IBD is the first ever dual-construct HVT vaccine to protect against IBD, in addition to Infectious Laryngotracheitis and Marek’s disease, in a single, non-reactive vaccine that can be administered via subcutaneous or in ovo application at the hatchery. Using the safer, more effective HVT-vaccine foundation, this breakthrough innovation protects against three diseases in one dose.
