Arm Intervention/treatment
Experimental: Group A Biological: Herpes simplex candidate vaccine- adjuvanted GSK 208141
Intramuscular injection, 3 doses

Placebo Comparator: Group B Biological: Placebo
Intramuscular injection, 3 doses

Primary Outcome Measures :
  1. 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 [ Time Frame: During a 30-day period after each vaccination (AEs), during 7 months after study start (SAEs) ]

Secondary Outcome Measures :
  1. 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 [ Time Frame: On the day of each vaccination and on the following 3 days ]
  2. 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 [ Time Frame: At day -90 to day -7, and at month 7 and month 13 ]
  3. 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 [ Time Frame: Day 0 through month 19 ]
  4. To evaluate the incidence and the types of the serious adverse experiences in both groups [ Time Frame: Month 7 to month 19 ]
  5. 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 [ Time Frame: Before vaccination, and one month and 7 months after vaccination ]
  6. To compare the anti-gD2 antibody responses between the subsets of HSV double seronegative and HSV-1 seropositive only vaccine recipients [ Time Frame: At months 7 and 13 ]
