Specific antibody titers in mice (n = 6) after vaccination with JOL1913+1917. Mice were either immunized intramuscularly with the PBS only, JOL1837 carrying the empty vector pJHL65 (Sal-vector) and constructs JOL1913+JOL1917 (im-Sal-HA-M2e), or intraperitoneally with JOL1913+JOL1917 (ip-Sal-HA-M2e) or orally with constructs JOL1913+1917 (po-Sal-HA-M2e). Serum samples were analyzed for HI activity after 28 days post-vaccination. Each data points represent mean ± S.D. ∗∗p < 0.01; ns, non-significant.
