Primary Outcome Measures
NameTimeMethod
Antibody Response to Hepatitis A - Participants With a Serological Response4 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 Response6 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 Titers6 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 Experience4 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.6 months

Systemic adverse experiences are unfavorable or unintended changes in the body after getting study vaccine. Collected the first 14 days after each of the 2 doses of hepatitis A vaccine (VAQTA™) (Days 1 to 14), given 6 months apart

Participants With 1 or More Injection-site Adverse Experience6 months

Injection-site adverse experiences collected the first 5 days after receipt of each dose of hepatitis A vaccine (VAQTA™) (Days 1 to 5) over the 6 months in which the 2 doses of vaccine were administered.

Participants With Elevated Temperature (≥102.2F/ ≥39.0C)6 months

Elevated temperatures measured the first 5 days after receipt of each dose of hepatitis A vaccine (VAQTA™) (Days 1 to 5) over the 6 months in which the 2 doses of vaccine were administered.

Participants With 1 or More Serious Vaccine-related Adverse Experience6 months

Serious vaccine-related adverse experience causes death, persistent or significant disability, causes or prolong a hospital stay, is a cancer, an overdose, or life-threatening. They were collected during the entire study and believed due to study vaccine
