Survival curves of SA14-14-2-vaccinated and NS1-immunized mice after JEV challenge. Groups of three-month-old SA14-14-2-vaccinated or NS1-immunized C3H mice (see Figure 1) were i.n. challenged with 1 × 10⁴ pfu of JEV SA14. The JEV-infected mice were monitored daily for 28 days. Survival curves of mice immunized with recombinant NS1 protein or injected with PBS were constructed using data from two experiments, with groups of 6–12 mice. JEV-vaccinated mice were tested once using eight mice. Control mice received PBS and were challenged with JEV.
