Fig. 6: HSV-2 neutralizing antibody titers induced by three serial vaccinations.

The sera dilution that showed a 50% or greater reduction in virus plaques compared to the virus/complement control was used and the Log₁₀ geometric mean titer (GMT) is presented. Horizontal line is the mean. a P < 0.001 vs No Vaccine, b P < 0.03 vs R2 IM and R2 IVag.
