Brief Summary

The aim of this study is to evaluate the long-term persistence of hepatitis A antibodies at 11, 12, 13, 14, 15, 16, 17, 18, 19 and 20 years after subjects received their first dose of a 2 dose vaccination schedule of hepatitis A vaccine.

Outcome Measures

Primary Outcomes (3)

  • Anti-hepatitis A Virus (Anti-HAV) Antibody Concentration

    Concentrations given as geometric mean concentration (GMC) expressed as milli-international unit per millilitre (mIU/mL). The laboratory assay was changed at Year 11, thus the blood samples were with both the old and the new assay for the sake of bridging.

    At Years 11, 12, 13, 14, 15, 16, 17, 18, 19 and 20 after the first vaccine dose of the 2-dose primary vaccination

  • Anti-hepatitis A Virus (Anti-HAV) Antibody Concentration

    Concentrations given as GMC expressed as mIU/mL.

    Before the additional dose, 14 days and 30 days after the additional dose

  • Number of Seropositive Subjects for Anti-HAV Antibodies.

    Seropositivity for anti-HAV antibodies defined as antibody concentrations ≥ 15 mIU/mL for Year 11 to Year 20 time points. The laboratory assay was changed at Year 11, thus the blood samples were with both the old and the new assay for the sake of bridging.

    From Year 11 to Year 20

Secondary Outcomes (5)

  • Number of Subjects Reporting Serious Adverse Events (SAE) Assessed by the Investigators as Related to Vaccination or to Study Procedures or Lack of Efficacy

    Years 11, 12, 13, 14, 15, 16, 17, 18, 19 and 20 after the first vaccine dose of the 2-dose primary vaccination

  • Number of Subjects Reporting Any and Grade 3 Solicited Local Symptoms

    During the 4-day (Day 0-3) follow-up period after additional vaccination

  • Number of Subjects Reporting Any, Grade 3 and Related Solicited General Symptoms

    During the 4-day (Day 0-3) follow-up period after additional vaccination

  • Number of Subjects Reporting Any, Grade 3 and Related Unsolicited Adverse Events (AE)

    During the 30-day follow-up period after additional vaccination (for subjects who received the additional vaccine dose between Year 11 and 15)

  • Number of Subjects Reporting Serious Adverse Events (SAE)

    During the follow-up period after additional vaccination up to Year 20

Study Arms (1)

Havrix Group

EXPERIMENTAL

Subjects who received 2 doses of Havrix™ (lot A, B or C) in the primary study. As lot to lot consistency was assessed during the primary study, the 3 groups (lot A, B or C) were pooled into the Havrix Group for data analyses during the long term follow-up.

Biological: Havrix™

Interventions

Havrix™BIOLOGICAL

2 doses at 6 months interval

Havrix Group

Eligibility Criteria

Age29 Years - 60 Years
Sexall

Age GroupsAdult (18-64)

You may qualify if:

  • Subjects who had received at least one dose of the study vaccine in the primary study
  • Written informed consent will have been obtained from the subjects before the blood sampling visit of each year.
