The HAI titer in JOL1814-immunized and control groups. HAI titers are expressed as log2 values of the highest dilution of serum that completely inhibited chicken RBC haemagglutination. A HAI titer at 7 weeks of age following post primary immunization; B HAI titer 11 weeks of age following post booster immunization. The SI values are presented as the mean ± SEM of each group. Significant differences in HAI titer value were estimated by calculating the GMT ± SD for each group. Oral: JOL1814 orally immunized group; IM: JOL1814 intramuscularly immunized group; VC: JOL1820 intramuscularly immunized group, and PC: PBS inoculated group. *p < 0.05 when compared with the PBS control group.
