| Type | Measure | Description | Time frame | Safety issue |
|---|---|---|---|---|
| Primary | To compare between herpes simplex vaccine and placebo recipients the general safety of the vaccine by recording all the unsolicited adverse experiences and all serious adverse experiences | During a 30-day period after each vaccination (AEs), during 7 months after study start (SAEs) | ||
| Secondary | To compare between vaccine and placebo recipients the incidence and severity of the reactogenicity as measured by recording the local reactions and the general symptoms | On the day of each vaccination and on the following 3 days | ||
| Secondary | To compare between vaccine and placebo recipients the effect on the haematological and biochemical parameters in subjects from 20% of the centers in each country | At day -90 to day -7, and at month 7 and month 13 | ||
| Secondary | To compare between vaccine and placebo recipients the effect on pre-existing herpes simplex virus infection by recording the frequency and severity of all herpes simplex clinical episodes | Day 0 through month 19 | ||
| Secondary | To evaluate the incidence and the types of the serious adverse experiences in both groups | Month 7 to month 19 | ||
| Secondary | To evaluate the humoral immune response to the vaccine by measuring the anti-gD2 antibodies in a subset of vaccine and placebo recipients from each of the serostatus groups | Before vaccination, and one month and 7 months after vaccination | ||
| Secondary | To compare the anti-gD2 antibody responses between the subsets of HSV double seronegative and HSV-1 seropositive only vaccine recipients | At months 7 and 13 |
