HI and virus neutralizing antibody titers in chickens after immunization with Salmonella-based influenza vaccines. Chickens (N = 12) were immunized with Sal-vector, Sal-HA, Sal-M2e, Sal-M2e-NA or Sal-HA-M2e-NA vaccine, and serum samples were analysed for HI (A) and VN titers (B) after 28 days post-vaccination. Each data points represent mean ± SD of five chickens per group. p < 0.05. ns: non-significant.
