Efficacy of GUMBOHATCH® against an experimental challenge with Infectious Bursal Disease virus strain UK2019 in broilers


Genome reassortment of the Infectious bursal disease virus (IBDV) contributes to the evolution and constant emergence of new strains. Hipra’s diagnostic services have repeatedly identified a new strain in several EU countries, which has been named UnitedKingdom.2019 (UK2019). This strain would be linked to subclinical outbreaks of IBD on farms in this area, suggesting a possible lack of efficacy of the control programmes used for this disease.

An efficacy trial was performed in order to assess whether GUMBOHATCH®, an immune complex vaccine against IBDV, would protect chickens from a UK2019 challenge.
