Study Endpoints
Primary Endpoints
Number of Subjects With a Varicella Vaccine Response
At 8 months post-transplantation = 1.5 months post-second dose of vaccination

Vaccine response was defined as: for initially seropositive subjects, an antibody titer at Month 8 post-transplantation above or equal to (≥) 4 fold the pre-vaccination antibody titer.

Anti-varicella Zoster Virus (Anti-VZV) Antibody Titers
At 8 months post-transplantation = 1.5 months post-second dose of vaccination

Antibody titers were measured by Indirect Immunofluorescence Assay (IFA) and presented as geometric mean titers (GMTs).

Secondary Endpoints
Number of Subjects With a Varicella Vaccine Response
At 6.5 months post-transplantation = 2 months post first dose of vaccination
Number of Seropositive Subjects for Anti-varicella Antibodies
At pre-transplantation (Month 0), pre-vaccination visit (at 4.5 months post-transplantation), Month 12 and Month 24 (5.5 and 17.5 months post-second dose of vaccination)
Anti-varicella Antibody Titers
At pre-transplantation (Month 0), pre-vaccination visit (4.5 months post-transplantation), Month 12 and Month 24 (5.5 and 17.5 post-second dose of vaccination)
