Outcome Measures

Primary Outcomes (1)

  • Immunogenicity with respect to components of the study vaccine in terms of antibody titres

    At each long-term follow-up (LTFU) visit (16-20 years after the first dose of primary vaccination)

Secondary Outcomes (1)

  • Occurrence of Serious adverse events (SAEs)

    During the entire study period (Year 16-20)

Study Arms (2)

2-dose Primed Group

EXPERIMENTAL

Adolescent subjects in this group received 2 doses of Twinrix Adult (720/20) (licensed as Ambirix in the EU) according to a 0, 6 months schedule in the primary study HAB-084 (208127/084).

Procedure: Blood sampling

3-dose Primed Group

EXPERIMENTAL

Adolescent subjects in this group received 3 doses of Twinrix Junior (360/10) according to a 0, 1, 6 months schedule in the primary study HAB-084 (208127/084).

Procedure: Blood sampling

Interventions

At Years 16 - 20 after first dose of the primary vaccination in HAB-084 (208127/084) study.

Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Subjects who, in the opinion of the investigator, can and will comply with the requirements of the protocol.
  • A male or female who received two/three doses of Twinrix according to his/her group allocation in study HAB-084 (208127/084), and received no further dose of any hepatitis A and/or B vaccine since then.
  • Written informed consent obtained from the subject.

You may not qualify if:

  • Chronic administration (defined as more than 14 days in total) of immunosuppressants or other immune-modifying drugs within six months prior to study entry. Inhaled and topical steroids are allowed.
  • Administration of long-acting immune-modifying drugs within six months prior to the study entry.
  • Concurrently participating in another clinical study, at any time during the study period, in which the subject has been or will be exposed to an investigational or a non-investigational vaccine/product (pharmaceutical product or device).
  • Administration of any hepatitis A and/or B vaccine at any time since completion of the primary vaccination series in HAB-084 (208127/084) study, including a challenge dose of the study vaccine, as a part of the study procedures, during the long-term persistence phase.
  • Documented history of hepatitis A or B disease since completion of the primary vaccination series in HAB-084 (208127/084) study.
  • Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination (no laboratory testing required).
  • Administration of immunoglobulins within six months prior to study entry.
