Primary Outcome Measures:
  • Number of Participants With Anti-hepatitis B Surface Antigen (HBs) Antibody Concentrations Above the Cut-off Value [ Time Frame: One month after the challenge dose of HBV vaccine ] [ Designated as safety issue: No ]
    Anti-HBs antibody cut-off value assessed was 100 milli-international unit per milliliter (mIU/mL)


Secondary Outcome Measures:
  • Number of Participants With Anti-HBs Antibody Concentrations Above the Cut-off Value [ Time Frame: Before challenge dose of HBV vaccine ] [ Designated as safety issue: No ]
    Anti-HBs antibody cut-off values assessed include 3.3, 10 and 100 mIU/mL

  • Number of Participants Reporting Solicited Local Symptoms [ Time Frame: During the 4-day follow-up period after the challenge dose of HBV vaccine. ] [ Designated as safety issue: No ]
    Solicited local symptoms assessed include pain, redness and swelling

  • Number of Participants Reporting Solicited General Symptoms [ Time Frame: During the 4-day follow-up period after the challenge dose of HBV vaccine. ] [ Designated as safety issue: No ]
    Solicited general symptoms assessed include fatigue, fever, gastrointestinal symptoms, and headache

  • Number of Participants Reporting Unsolicited Adverse Events [ Time Frame: During the 31-day follow-up period after the challenge dose of HBV vaccine. ] [ Designated as safety issue: No ]
    An Adverse Event is any untoward medical occurrence in a clinical investigation subject, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product.

  • Number of Participants Reporting Serious Adverse Events (SAE) [ Time Frame: After the challenge dose of HBV vaccine. ] [ Designated as safety issue: No ]

    An SAE is any untoward medical occurrence that:

    results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect in the offspring of a study subject, or may evolve into one of the outcomes listed above.

Criteria

Inclusion Criteria:

  • Subjects who the investigator believes that their parents/guardians can and will comply with the requirements of the protocol.
  • A male or female of 7 to 8 years of age (from and including the 7th birthday up to but excluding the 9th birthday) at the time of enrolment.
  • With documented evidence of previous vaccination with three consecutive doses of Engerix™-B in Germany
  • Written informed consent obtained from the parents or guardians of the subject at the time of enrolment.
  • Healthy subjects as established by medical history and clinical examination before entering into the study.

Exclusion Criteria:

  • Evidence of previous hepatitis B booster vaccination since administration of the third dose of Engerix™-B vaccine.
  • History of or intercurrent hepatitis B disease.
  • Hepatitis B vaccination at birth.
  • Planned administration/administration of a vaccine not foreseen by the study protocol during the period starting from 30 days before HBV vaccine challenge and ending 30 days after.
  • Administration of immunoglobulins and/or any blood products within the three months preceding HBV vaccine challenge or planned administration during the study period.
  • Chronic administration (defined as more than 14 days) of immunosuppressants or other immune-modifying drugs within six months prior to the HBV vaccine challenge.
  • Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination
