A trial for emergency vaccination against IBDV 48-hour post experimental infection__ widespread and tends to infect most commercial given with or without some immunostimualnts,namely; Pind-Avi (Fowl pox virus inactivated by
gamma rays), Ultracorn® (Corynebacterium cutis lysate), Levamisole hydrochloride® and Transferrin. The results revealed that emergency vaccination of infected chicks was useless in controlling mortality or bursal damage (which was evidenced by bursal lesion score & bursal lymphoid tissue lesions). The use of these immunostimulants alone improved the protection % but had not restored the bursal damage with varying degree of stimualtion of non-specific immune response in the following order: Transferrin, ultracorn®, Pind-Avi finally levamisole. The combination of emergency 
vaccine with immunostimulant didn't show a Significant control point.
