Fig. 1. F1/V vaccine increased protective levels of antibody, CD4+ T-cell, and IFN-γ responses.
a Macrophage-protective levels of antibodies were statistically significantly increased from pre-vaccination on days 14 and 28 with highest response on day 28 post-second vaccination (Wilcoxon signed-rank test P-values are shown). b–d CD4+ that expressed IL-10, IL-4, or co-expressed TNF-α and IFN-γ were statistically increased from pre-vaccination on day 28 but not day 14. e IFN-γ cytokine concentrations measured in culture supernatants were statistically significantly increased from pre-vaccination on day 14 but not day 28. Statistical significance is based on Wilcoxon signed-rank test.
