Primary Outcome Measures:
  • Immunogenicity [ Time Frame: half a year ] [ Designated as safety issue: No ]
    Geometric mean titer of Varicella zoster virus-specific IgG, VZV-specific T- cells per 106 peripheral mononuclear cells, Frequency of VZV-specific T- cells of total T-cells, CD4+ T-cells in different HIV-positive persons.

  • Safety [ Time Frame: half a year ] [ Designated as safety issue: Yes ]
    Number of Participants with Adverse Events as a Measure of Safety and Tolerability"
