Study Arms:
- Diabetes Group (Type: EXPERIMENTAL): Subjects diagnosed with type 2 diabetes within the five year period before study start who received 3 doses of Engerix™-B vaccine (HBV) at 0, 1 and 6 months. The vaccine was administered intramuscularly (IM) into the deltoid region of the non-dominant arm.
- Control Group (Type: ACTIVE_COMPARATOR): Subjects with no diagnosis or documented history of diabetes who received 3 doses of Engerix™-B (HBV) vaccine at 0, 1 and 6 months. The vaccine was administered intramuscularly into the deltoid region of the non-dominant arm.
