Induction of HA-518-epitope-specific and IFN-γ-secreting spleen cells in ducks immunized with C-KCE-HA vaccine. HA-specific responses of splenocytes taken 1, 4, 12, 36 weeks post-vaccination as determined by IFN-γ-ELISPOT assay inducing HA-518-epitope-specific. Data represent means standard errors of the mean of triplicate determinations for a minimum of three ducks per group.
