HI titers and T cell responses at day 28 after the first immunization in SD rats. (a) The serum HI titers were detected by HI against H1N1, H3N2, BV, and BY at day 28. The data represent geometric mean with 95% CI. (b-d) T cell responses were measured by IFN-γ ELISpot assays for various groups. (e–g) T cell responses were assessed by IL-4 ELISpot. Compared with 6 μg of IIV4, *P < 0.05, ***P < 0.001, ****P < 0.0001. N = 3 to 6.
