Study Overview
Brief Summary
Hepatitis A vaccine will be given either alone or together with measles, mumps, rubella, and varicella vaccine and pneumococcal 7-valent conjugate vaccine at the first dose and together with measles, mumps, rubella, and varicella [Oka/Merck] virus vaccine at the second dose. Immunogenicity and safety data will be collected after each dose of vaccine.
Detailed Description
Vaccines: V251, Hepatitis A Vaccine, Inactivated (VAQTA™) administered with Measles, Mumps, Rubella and Varicella Vaccine (ProQuad™) and Pneumococcal 7-Valent Conjugate Vaccine (Prevnar™) will have a Duration of Treatment: 2 Doses, 6 months apart.
Vaccine: Hepatitis A Vaccine, Inactivated (VAQTA™), administered alone will have a Duration of Treatment: 2 Doses, 6 months apart.

Outcomes
Primary Outcomes
Antibody Response to Hepatitis A - Participants With a Serological Response
Time Frame: 4 weeks Postdose 2 of hepatitis A vaccine (VAQTA™)
Number of participants with titer ≥10 mIU/mL, i.e., seropositive for hepatitis A antibody, regardless of initial serostatus
Antibody Response to Varicella - Participants With a Serological Response
Time Frame: 6 weeks Postdose 1 of varicella-containing vaccine (ProQuad™)
Participants with varicella baseline antibody titer \<1.25 gpELISA units/mL and Postdose 1 titers ≥1.25 gpELISA units/mL (seroconversion) and ≥5 gpELISA units/mL (seroprotection)
Antibody Response to Streptococcus Pneumoniae - Geometric Mean Titers
Time Frame: 6 weeks Postvaccination of pneumococcal 7-valent conjugate vaccine (Prevnar™)
Serum antibodies to serotype-specific pneumococcal polysaccharides were determined by enzyme-linked immunosorbent assay
Participants With 1 or More Systemic Adverse Experience
Time Frame: 4 weeks post dose 2
Systemic adverse experiences are unfavorable or unintended changes in the body after getting study vaccine. They are collected the first 14 days after receipt of dose 2 of hepatitis A vaccine (VAQTA™) (Days 1 to 14) within the 4 week study period.
Participants With 1 or More Systemic Adverse Experience.
