Concentrations of interferon‐γ (IFN‐γ) in extracts of vaginal mucus from immunized mice before and 20 hr after vaginal challenge with wild‐type herpes simplex virus type‐2 (HSV‐2). The mean IFN‐γ concentrations in vaginal secretions before challenge were not significantly different from 0·0 (P > 0·50 in each group, two‐tailed t‐tests). The IFN‐γ concentration in nasally immunized mice after challenge was significantly lower than in the two vaginally immunized groups (P = 0·0008, three‐group analysis of variance [anova]).
