The purpose of this study is to assess non-inferiority of two different vaccination regimens using GSK Biological's MMRV vaccine (two doses at 9 and 15 months) or Priorix™ (9 months) and one dose of MMRV vaccine (15 months) to the current standard of care which is Priorix™ administered at 9 months of age followed by concomitant administration of Priorix™ with Varilrix™ at 15 months of age in a measles endemic environment such as India.

Number of Subjects Seroconverted for Measles, Mumps, Rubella and Varicella Antibodies
Seroconversion was defined as the appearance of antibodies \[i.e. concentration/titre greater than or equal to (≥) the cut-off value\] in the serum of subjects seronegative before vaccination. The cut-off values for seroconversion were 150 milli-international units per milliliter (mIU/mL), 231 units per milliliter (U/mL), 4 international units per milliliter (IU/mL) and for immunoglobulin G (IgG) varicella antibodies 1:4 dilution for measles, mumps, rubella and varicella, respectively.
Time frame: At 42 - 56 days after the second vaccination dose at week 30
Number of Seroconverted Subjects for Measles, Mumps, Rubella and Varicella Antibodies
Seroconversion was defined as the appearance of antibodies (i.e. concentration/titre ≥ the cut-off value) in the serum of subjects seronegative before vaccination. The cut-off values for seroconversion were 150 mIU/mL, 231 U/mL, 4 IU/mL and for IgG varicella antibodies 1:4 dilution for measles, mumps, rubella and varicella, respectively.
Time frame: Approximately 42 to 56 days after the first vaccine dose at week 6
Antibody Concentrations Against Measles, Mumps, Rubella and Varicella Viruses
Antibody concentrations were summarized by geometric mean concentrations (GMCs) with their 95% confidence intervals (CIs).
Time frame: At 42 - 56 days after the first (at Week 6) and second (at Week 30) vaccination dose
Number of Subjects Reporting Any and Grade 3 Solicited Local Symptoms
Assessed solicited local symptoms were pain, redness and swelling. Any = occurrence of the symptom regardless of intensity grade. Grade 3 pain = cried when limb was moved/spontaneously painful. Grade 3 redness/swelling = redness/swelling spreading beyond 20 millimeters (mm) of injection site.
Time frame: During the 4-day (Days 0-3) post-vaccination period following each dose (Dose 1 and Dose 2)

Number of Subjects Reporting Any, Grade 3 and Related Solicited General Symptoms
Assessed solicited general symptoms were meningism and parotid gland swelling. Any = occurrence of the symptom regardless of intensity grade or relationship to vaccination. Grade 3 meningism and parotid gland swelling = meningism/parotid gland swelling which prevented normal everyday activities. Related = symptom assessed by the investigator as related to the vaccination.
Time frame: During the 43-day (Days 0-42) post-vaccination period following each dose (Dose 1 and Dose 2)
Number of Subjects Reporting Any, Grade 3 and Related Fever
Any fever was defined as fever ≥ 38.0°C and grade 3 fever was defined as fever \> 39.5°C after vaccination. Related fever was defined as fever assessed by the investigator as related to the vaccination.
Time frame: During the 43-day (Days 0-42) post-vaccination period following each dose (Dose 1 and Dose 2)
Number of Subjects Reporting Any, Grade 3 and Related Rash
Any rash was defined as incidence of a rash regardless of intensity grade or relationship to vaccination and grade 3 rash greater than (\>) 150 lesions. Related rash was defined as rash assessed by the investigator as causally related to the vaccination
Time frame: During the 43-day (Days 0-42) post-vaccination period following each dose (Dose 1 and Dose 2)
Number of Subjects Reporting Any Unsolicited Adverse Event
An unsolicited Adverse Event (AE) covers any untoward medical occurrence in a clinical investigation subject temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. Any was defined as an AE reported in addition to those solicited during the clinical study. Also any 'solicited' symptom with onset outside the specified period of follow-up for solicited symptoms was reported as an unsolicited adverse event.
Time frame: Within 43-day (Days 0-42) after the first and second vaccination dose
Number of Subjects With Serious Adverse Events (SAEs)
Serious adverse events (SAEs) assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization, result in disability/incapacity or congenital anomaly/birth defect in the offspring of a study subject.
Time frame: From the first study dose up to study end (Month 0 to Month 7.5 approximately)
