AVIAN VIRAL VECTOR VACCINES FOR INFECTIOUS BURSAL DISEASE

Infectious bursal disease (IBD) is one of the economically important avian diseases for the poultry industry. In addition to traditional inactivated and attenuated vaccines, recent research has developed other types of vaccines to make IBD vaccines more adaptable for preventing different strain types and avoid the interference of maternal antibodies. Avian viral vector vaccines are emphasized in the present review. The background of IBD, virus and viral vectors is introduced. Different avian viral vectors for IBD, including their benefits and drawbacks, and the potential use of IBD virus as the viral vector are addressed.
