Abstract: Infectious Bursal Disease（IBD）is an acute，highly contagious infectious disease caused by infectious bursal disease virus（IBDV）mainly affecting young chickens. It is characterized by severe injury of bursa of Fabricius and immunosuppression. Since 1980s，IBDV has been found in many countries and regions. In addition，IBDV variants with increased virulence，namely variant IBDV（vIBDV）and variant/very virulent IBDV（vvIBDV）had emerged. IBD cause significant economic losses to the poultry industry worldwide. At present，comprehensive prevention and control measures combining vaccination and biosafety are mainly adopted. In this paper，IBD attenuated live vaccines，inactivated vaccines，immune complex vaccines，recombinant vector live vaccines，subunit vaccines and DNA vaccines that have been commercialized or are under development are reviewed，in order to provide theoretical reference for better prevention and control of IBD.
