Study Summary

The purpose of this study is to assess the consistency of immune response to three different lots of GSK's investigational varicella vaccine (VNS Vaccine), and to compare the safety and immune response of VNS vaccine to an already approved varicella vaccine (VV) known as Varivax. The study will be conducted in healthy children aged 12 to 15 months, who have neither contracted varicella nor received a varicella vaccination.

Primary Outcome

Seroresponse is defined as post-vaccination (Day 43) anti-VZV gE IgG antibody concentration greater than or equal to (\>=) 300 milli-international units per milliliter (mIU/mL) among participants who were seronegative \[(antibody concentration less than (\<) LLOQ (Lower limit of quantification)\] before vaccination. A seronegative participant is a participant whose antibody concentration is below the LLOQ of the assay. A seropositive participant is a participant whose antibody concentration is g
