Development and large-scale use of recombinant VP2 vaccine for the prevention of infectious bursal disease of chickens.

Infectious bursal disease virus (IBDV) is the causative agent of Gumboro disease, an infectious disease of global economic importance in poultry. One of the most effective types of inactivated IBDV vaccine is produced by infecting young chickens with a virulent strain, sacrificing them and extracting the virus from the bursa of Fabricius. The goal of this study was to produce an effective subunit vaccine against IBDV thereby providing an effective means of combating the disease.
