Study Summary

The purpose of this study is to evaluate the effect of recombinant human heat shock protein 70-polyvalent peptide complex (HerpV) vaccine administration on recurring episodes of genital herpes by evaluating viral shedding before and after treatment.

Primary Outcome

The viral shedding rate was defined as the number of days with genital swab positive for herpes simplex virus (HSV) deoxyribonucleic acid (DNA), as measured by quantitative real-time polymerase chain reaction (PCR), relative to the total number of days with available swabs.
