Brief Summary:
To assess the safety and immunogenicity of a booster dose of hepatitis B vaccine in children who have received a 3-dose primary series of either RECOMBIVAX HB or ENGERIX-B. The primary vaccination series (was given 4 to 8 years prior to study entry and consisted of a licensed hepatitis B vaccine product (either RECOMBIVAX HB or ENGERIX-B). The booster dose given in this study will be either an investigational Merck product (Modified Process Hepatitis B Vaccine) or licensed ENGERIX-B vaccine.

Participants had previously received a primary series of 3 doses of RECOMBIVAX HB™ (5 µg (micrograms) per dose) during the first year of life outside of the context of the study.

During this study, participants received a dose of 10µg/per 0.5 ml ENGERIX-B™ (Booster Dose)

 Biological: Comparator: Comparator: ENGERIX-B
Single dose 10 µg/0.5ml ENGERIX-B
Active Comparator: 5 µg Modified Process Hepatitis B Vaccine Booster (Group 3)

Participants had previously received a primary series of 3 doses of ENGERIX-B™ (10 µg (micrograms) per dose) during the first year of life outside of the context of the study.

During this study, participants received a 5µg/0.5 ml dose of Modified Process Hepatitis B Vaccine, (Booster Dose).

 Biological: Comparator: Modified Process Hepatitis B Vaccine
