WNVΔVax constructs elicit high antibody titers in mice. Mice were vaccinated IP at doses of 100 and 1000 IU. At 21 days post-vaccination, serum was collected and PRNT₉₀ titers were determined for each animal. PRNT₉₀ values indicated represent the reciprocal of serum titers. Grey bars represent geometric mean titers for each vaccine at each dose, and error bars represent standard error.
