简要总结
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.
详细描述
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.

结局指标
主要结局
Antibody Response to Hepatitis A - Participants With a Serological Response
时间窗: 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
时间窗: 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
时间窗: 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
时间窗: 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.
时间窗: 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 Experience
时间窗: 6 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)
时间窗: 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 Experience
时间窗: 6 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
