Brief summary: This two-stage study evaluates the immunogenicity, safety, and tolerability of the administration of VAQTA™ (Hepatitis A Vaccine, Inactivated) concomitantly with PedvaxHIB™ (Haemophilus B Conjugate Vaccine \[Meningococcal Protein Conjugate\]) and Infanrix™ (Diphtheria and Tetanus Toxoids and Acellular Pertussis Vaccine Adsorbed, GlaxoSmithKline) versus the administration of VAQTA™ in healthy children 15 months of age at study entry.

Detailed description: In stage I, VAQTA™ given concomitantly with Infanrix™ and/or PedvaxHIB™ was evaluated.

In stage 2: Two (2) doses of the VAQTA™ vaccine were administered at least 6 months apart. Safety data was collected after each dose.

Eligibility criteria: Inclusion Criteria:

* Stage 1) Healthy males and females 15 months of age with no active liver disease and a negative history of hepatitis A who have been vaccinated against Haemophilus influenzae type b (Hib), diphtheria, tetanus, and pertussis diseases
* Stage 2) Healthy males and females 12 to 17 months of age with no active liver disease and a negative history of hepatitis A

Exclusion Criteria:

* Stage 1) Males and females previously vaccinated with hepatitis A vaccine, any immune deficiency, a history of allergy to any of the vaccine components, a history of seizure disorder or a neurologic disorder that would contraindicate pertussis vaccine, or a bleeding disorder
* Stage 2) Males and females previously vaccinated with hepatitis A vaccine, any immune deficiency, a history of allergy to any of the vaccine components, or a history of bleeding disorder

Primary outcomes:
measure: Seropositivity Rate (SPR) to Hepatitis A
timeFrame: 4 weeks after dose 2 of VAQTA™
measure: Antibody Response Rate to Haemophilus Influenzae Type b (Hib)
timeFrame: 4 weeks postvaccination with PedvaxHIB™
measure: Number of Participants With Adverse Events (AE)
timeFrame: Days 1 to 14 after any dose of VAQTA™ for systemic AEs, and Days 1 to 5 after any dose of VAQTA™ for injection-site AEs
measure: Geometric Mean Titers (GMTs) to Antibodies for the Pertussis Toxin (PT), Pertussis Filamentous Hemagglutinin Antibody (FHA), and Pertactin (PRN) Components of Infanrix™
timeFrame: 4 weeks postvaccination with Infanrix™
