Neutralizing antibody titers obtained for individual sera are reproducible across assays.

<p>Post-vaccination sera from two different vaccinated test subjects that represented a low and intermediate response were tested against two HSV-1 primary isolates (#1 and 5) and two HSV-2 primary isolates (#6 and 8). Each symbol represents the titer derived in an independent neutralization assay. The mean ± SEM of 4 assays with each serum are shown.
