This is a study to evaluate the immune response and safety of GSK Biologicals 2-dose inactivated hepatitis A vaccine when administered with a measles/mumps/rubella vaccine and a varicella (chickenpox) vaccine in children as young as 15 months of age. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
An open, controlled comparison of Havrix™ administered alone or with MMR II and Varivax™. The three groups evaluated are: 1) Havrix™ alone, 2) Havrix™ + MMR II and Varivax™ and 3) MMR II and Varivax™ followed by Havrix™ one month later.

Anti-hepatitis A Virus (HAV) Antibody Concentrations in HAV and HAV+MMR+V Groups.
Concentrations are given as geometric mean concentrations (GMCs) expressed as milli-international units per milliliter (mIU/mL).
Time frame: 31 days following the second dose of Havrix®
Number of Subjects With Anti-hepatitis A Virus (HAV) Antibody Concentration Equal or Above the Cut-off Value in HAV and HAV+MMR+V Groups
Anti-HAV antibody cut-off value assessed include 15 milli-international units per milliliter (mIU/mL).
Time frame: 31 days following the second dose of Havrix®
Number of Subjects Seroconverted for Anti-measle, Anti-mumps and Anti-varicella Antibodies in HAV+MMR+V and MMR+V→HAV Groups
Seroconversion is defined as the appearance of antibodies with titers greater than or equal to the predefined cut-off value in the serum of subject seronegative before vaccination. Cut-off values assessed include 150 milli-international units per milliliter (mIU/mL) for anti-measles antibodies, 28 Effective Dose 50 (ED50) for anti-mumps antibodies and 1:5 for anti-varicella antibodies.
Time frame: 42 days following the administration of M-M-R®II and VARIVAX®
Number of Subjects With Vaccine Response for Anti-rubella Antibodies in HAV+MMR+V and MMR+V→HAV Groups
Vaccine response is defined as the appearance of antibodies with titers greater than or equal to the predefined cut-off value in the serum of subject seronegative before vaccination. Cut-off value assessed include 10 milli-international units per milliliter (mIU/mL).
Time frame: 42 days following administration of M-M-R®II and VARIVAX®
Anti-measles, Anti-mumps, Anti-rubella and Anti-varicella Antibody Titers in HAV+MMR+V and MMR+V→HAV Groups
Titers are given as geometric mean titers (GMTs).

Time frame: 42 days following the first dose of Havrix®
Number of Subjects With Anti-hepatitis A Virus (HAV) Antibody Concentration Equal or Above the Cut-off Value in HAV and HAV+MMR+V Groups
Anti-HAV antibody cut-off value assessed include 15 milli-international units per millilitre (mIU/mL).
Time frame: 42 days following the first dose of Havrix®
Anti-hepatitis A Virus (HAV) Antibody Concentrations in MMR+V→HAV Group
Concentrations are given as geometric mean concentrations (GMCs).
Time frame: 31 days following the second dose of Havrix®
Number of Subjects With Anti-hepatitis A Virus (HAV) Antibody Concentrations Above the Cut-off Value in MMR+V→HAV Group
Anti-HAV antibody cut-off value assessed include 15 milli-international units per millilitre (mIU/mL).
Time frame: 31 days following the second dose of Havrix®
Number of Subjects With Vaccine Response to Havrix®
Vaccine response was defined as: 1) a detectable anti-hepatitis A virus (HAV) antibody concentration 31 days following the second dose in subjects who were initially seronegative; and 2) a 2-fold increase in anti-HAV antibody concentrations above the pre-study concentration 31 days following the second dose in subjects who were initially seropositive.
Time frame: 31 days following the second dose of Havrix®
Number of Subjects Reporting Solicited Local Symptoms
Solicited local symptoms assessed include pain, rash (local), redness and swelling.
Time frame: During the 4-day period following each dose of vaccine
Number of Subjects Reporting Solicited General Symptoms
Solicited general symptoms assessed include drowsiness, fever, irritability, loss of appetite and rash (general).
Time frame: During the 4-day period following each dose of vaccine
Number of Subjects Reporting Measles, Mumps, Rubella and Varicella Specific Solicited General Adverse Events
Specific adverse events assessed include papules, vesicles, crusts, parotid/salivary gland swelling and suspected signs of meningitis/febrile seizures.
Time frame: During the 43-day period following each dose of vaccine
Number of Subjects Reporting Unsolicited Adverse Events (AEs)
Unsolicited AE covers any AE reported in addition to those solicited during the clinical study and any solicited symptom with onset outside the specified period of follow-up for solicited symptoms
Time frame: During the 31-day period following each dose of vaccine
Number of Subjects Reporting Serious Adverse Events (SAEs)
SAEs assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization, result in disability/incapacity or are a congenital anomaly/birth defect in the offspring of a study subject.
