Primary Outcome Measures

Name	Time	Method
Anti-VZV Antibody Concentrations	One month after the second vaccination (Month 3)	Concentrations were determined by enzyme-linked immunosorbent assay (ELISA) and are presented as geometric mean concentrations (GMCs), expressed in milli-international units per milliliter (mIU/mL).
Frequency of gE-specific Cluster of Differentiation 4 (CD4+) T-cells Expressing at Least 2 Different Immunological Activation Markers	One month after the second vaccination (Month 3)	The analysis focused on CD4+ T-cells expressing at least 2 immunological activation markers among Interferon gamma (IFN-γ), Interleukin 2 (IL-2), Tumour Necrosis Factor alpha (TNF-α) and CD40 Ligand (CD40L). Frequencies were determined by in vitro Intracellular Cytokine Staining (ICS).
Frequency of Varicella-Zoster Virus (VZV)-Specific CD4+ T-cells Expressing at Least 2 Different Immunological Activation Markers	One month after the second vaccination (Month 3)	The analysis focused on CD4+ T-cells expressing at least 2 immunological activation markers among Interferon gamma (IFN-γ), Interleukin 2 (IL-2), Tumour Necrosis Factor alpha (TNF-α) and CD40 Ligand (CD40L). Frequencies were determined by in vitro Intracellular Cytokine Staining (ICS).
Anti-glycoprotein E (gE) Antibody Concentrations	One month after the second vaccination (Month 3)	Concentrations were determined by enzyme-linked immunosorbent assay (ELISA) and are presented as geometric mean concentrations (GMCs), expressed in milli-international units per milliliter (mIU/mL).

Frequencies were determined by in vitro Intracellular Cytokine Staining (ICS).
Number of Subjects With Any and Grade 3 Solicited Local Symptoms	During the 7-day (Days 0-6) post-vaccination period after each dose and across doses	Assessed solicited local symptoms were pain, redness and swelling. Any = occurrence of the symptom regardless of intensity grade. Grade 3 pain = pain that prevented normal activity.

Any was defined as the occurrence of any unsolicited AE regardless of intensity grade or relation to vaccination. Grade 3 AE = an AE which prevented normal, everyday activities. Related = AE assessed by the investigator as related to the vaccination.
