Log10 IBDV antibody titre of different groups immunized with various vaccines. Eight‐day‐old chickens vaccinated orally with 1 ml of 109 CFU per ml PBS, Negative control (pPG612/LP), pPG612‐VP2/LP or pPG612‐T7g10‐VP2/LP. Antibodies were detected in serum collected at 0, 10, 22, 35 and 44 days following the first oral vaccination. Titres were calculated by comparing the absorbance (A 650) values of the unknown sample to that of the positive control sample. **P < 0·01 vs pPG612/LP, # P < 0·05 vs pPG612‐VP2/LP group.
