Serious adverse events (SAEs) assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization or result in disability/incapacity.

The analyses were performed on the Total Vaccinated cohort, which included all subjects who received at least one dose of the study vaccine and for whom data were available.

Assessed solicited local symptoms were pain, redness and swelling. Any = occurrence of any local symptom regardless of intensity grade. Grade 3 pain = pain that prevented normal activities. Grade 3 redness/swelling = greater than (>) 30mm diameter and persisting more than 24 hours.

The analyses were performed on the Total Vaccinated cohort, only on subjects with their symptom sheets completed, who received at least one dose of the study vaccine and for whom data were available.

Assessed solicited general symptoms were arthralgia, fatigue, headache, malaise, rash, temperature [defined as oral temperature equal to or above (≥) 37.5 degrees Celsius (°C)] and urticaria. Any = occurrence of any general symptom regardless of intensity grade or relation to vaccination. Grade 3 arthralgia, fatigue, headache, malaise, rash = general symptom that prevented normal activity. Grade 3 temperature = greater than 39 degrees Celsius (°C). Grade 3 urticaria = urticaria distributed on at least 4 body areas. Related = general symptom assessed by the investigator as causally related to the study vaccination.

The analyses were performed on the Total Vaccinated cohort, only on subjects with their symptom sheets completed, who received at least one dose of the study vaccine and for whom data were available.

An unsolicited AE covers any untoward medical occurrence in a clinical investigation subject temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product and reported in addition to those solicited during the clinical study and any solicited symptom with onset outside the specified period of follow-up for solicited symptoms. Any was defined as the occurrence of any unsolicited AE regardless of intensity grade or relation to vaccination. Grade 3 = event which prevented normal, everyday activities. In adults/ adolescents, such an AE would, for example, prevent attendance at work/ school and would necessitate the administration of corrective therapy. Related = event assessed by the investigator as causally related to study vaccination.

The analyses were performed on the Total Vaccinated cohort, which included all subjects who received at least one dose of the study vaccine and for whom data were available.

Assessed parameters were alanine aminotransferase (ALT), creatinine (CREA), haematocrit (Hct), platelets (PLA), red blood cells (RBC), urea and white blood cells (WBC). A subset of subjects was formed for these analyses. Subjects were categorized according to their results at pre-vaccination at Month 0 (PRE) which were normal, above normal or below the normal range. Per parameter and range, it was assessed whether laboratory values of the subjects were normal, above normal or below the normal range at other timepoints. This outcome presents ALT results.

Concentrations are presented as geometric mean concentrations (GMCs), expressed in ELISA units per millilitre (EU/mL). Analysis was based on an immunogenicity subset, stratified by initial serostatus: HSV seronegative (-)/ seropositive (+), this included gD2-AS04 vaccine recipients, as follows: HSV 1 and HSV 2 seronegative (HSV1-/2-) and HSV 1 seropositive and HSV 2 seronegative (HSV1+/2-)

The analysis was performed on the ATP cohort for immunogenicity, in a predefined immunogenicity subset of HSV vaccine recipients (gD2-AS04 Group) who underwent assessment of biochemical and hematological parameters. Data from participants in the "Havrix Group" and "Saline Group" were not collected.

Concentrations are presented as geometric mean concentrations (GMCs), expressed in ELISA units per millilitre (EU/mL). The subset of subjects used for this analysis was 50% of the pre-defined subset of subjects that underwent assessment of biochemical and hematological parameters.

The analyses were performed on the According-To-Protocol cohort for immunogenicity, which included all evaluable subjects included in the immunogenicity subset for whom data concerning immunogenicity outcome measures were available (for whom assay results were available for antibodies against the study vaccine antigen component after Vaccination).
