After infection on the other hand, the F1 (mean = 12.35 ηg/ml), F2 (mean = 9.30 ηg/ml) and F3 (mean = 21.84 ηg/ml) vaccines were superior to saline controls (IC95%–1.65 to 8.10 ηg/ml) and the F1sap and F3sap vaccine showed higher IFN-γ levels than the NH36sap vaccine (0.08–11.11 ηg/ml) (Table 2). This evidence concerns the gene IFNG and infection.
