| Main Objective: To demonstrate non-inferiority of the anti-HAV immune response (with respect to both seropositivity rates and GMCs) 31 days following the second dose of Havrix when the first dose of Havrix is co-administered with Infanrix and ActHIB (HAV+DTaP+HIB Group) compared to Havrix given alone (HAV Group). To demonstrate the non-inferiority of the anti-diphtheria (D) and anti-tetanus (T) seroprotection rates; anti-pertussis (PT), anti-filamentous hemagglutinin (FHA) and anti-pertactin (PRN) GMCs and vaccine response rates; and anti-polyribosylribitol phosphate (PRP) seroprotection rate 31 days following the co-administration of Infanrix and ActHIB with the first dose of Havrix (HAV+DTaP+HIB Group) compared to Infanrix and ActHIB given alone (DTaP+HIB?HAV Group). ;Secondary Objective: Non-inferiority of the anti-PT, anti-FHA & anti-PRN im-mune response 31 days post the co-administration of In-fanrix and ActHIB with dose 1 of Havrix (HAV+DTaP+HIB Group) vs. Infanrix & ActHIB given alone (DTaP+HIB?HAV Group). Anti-D, anti-T anti-PRP, anti-PT, anti-FHA, anti-PRN & anti-PRP immune responses 31 days post the co-administration of Infanrix & ActHIB with dose 1 of Havrix in the HAV+DTaP+HIB Group & the DTaP+HIB?HAV Group. Anti-HAV immune response 31 days post dose 1 of Havrix in the HAV Group & the HAV+DTaP+HIB Group. Vaccine response to Havrix 31 days fpost dose 2 of Havrix for all groups, Incidence & intensity of solicited local and generalAEs during the 4-day (Days 0-3) period post each dose. Incidence, nature, intensity & causal relationship to vac-cination of unsolicited AEs post each dose of study vac-cine(s) during the 31-day) follow-up period & SAEs NOCIs & MAEs in each group during the Active Phase & the ESFU of the study. ;Primary end point(s): Anti-HAV seropositivity rates and GMCs following the second dose of Havrix in the HAV Group and the HAV+DTaP+HIB Group.

Anti-PT, anti-FHA, anti-PRN and anti-PRP seropositivity rates following the administration of Infanrix and ActHIB in the HAV+DTaP+HIB Group and the DTaP+HIB?HAV Group. Anti-HAV GMCs and seropositivity rates following the first dose of Havrix in the HAV Group and the HAV+DTaP+HIB Group. Anti-HAV GMCs and seropositivity rates following the second dose of Havrix in the DTaP+HIB?HAV Group. Vaccine response to Havrix following the second dose in all three groups. Incidence and intensity of solicited local AEs. Incidence, intensity and causal relationship to vaccination of solicited general AEs. Incidence, nature, intensity and causal relationship to vaccination of unsolicited AEs. Incidence, nature, intensity and causal relationship to vaccination of SAEs, new chronic illnesses and medically significant events in each group. ;Timepoint(s) of evaluation of this end point: For anti-D, anti-T and anti-PRP GMCs and anti-PT, anti-FHA, anti-PRN and anti-PRP seropositivity rates: At Visit 3 (Month 0) For anti-HAV GMCs and seropositivity rates and vaccine response rate: At Visit 5 (Month 7-10) For solicited local and general symptoms: During the 4-day period (Days 0-3) following each dose of study vaccine(s) in each group. For unsolicited AEs: During the 31-day period (Days 0-30) following each dose of study vaccine(s) in each group.
