| Primary | Number of Subjects Seroconverted for Measles, Mumps, Rubella and Varicella Zoster Virus (VZV) Antibodies Above the Cut-off Values | Seroconversion was defined as the appearance of antibodies [i.e. titer greater than or equal to (≥) the cut-off value] in the sera of subjects seronegative [i.e. titer below (<) cut-off value] before vaccination. Cut-off values were the following: Anti-measles concentration ≥ 150 milli-international units per milliliter (mIU/mL); Anti-mumps concentration ≥ 231 units per milliliter (U/mL); Anti-rubella concentration ≥ 4 international units per milliliter (IU/mL); Anti-VZV titer ≥ 1:4 dilution. | The analysis was performed on the According-To-Protocol (ATP) cohort for immunogenicity,which included all evaluable subjects who were seronegative for at least one vaccine antigen at baseline and for whom pre-vaccination and post-vaccination serology results were available. | Posted | | Count of Participants | | Participants | | At 42 days post-vaccination | | | | ID | Title | Description |
