About this study

At present, children less than 15 y of age have been regarded as a key group for hepatitis B immunization in China. However, there is not yet special immunization strategy for population above 15 y of age. In this study, we investigated the seroprevalence of hepatitis B and immune response to HB vaccine among Chinese college students to uncover the need on universal mass vaccination or booster immunization only for students with HBV vaccination history against hepatitis B in Chinese college students to inform decision making.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Anti-HBs immune response in participants negative for HB sAg, anti-HBs and anti-HBc

    Measured: Anti-HBs was assayed at Month 7

Secondary outcomes (4)
  1. Seroprevalence for HBsAg, anti-HBs and anti-HBc in Chinese college students

    Measured: seroprevalence at baseline

  2. Anti-HBs immune response in participants negative for HBsAg, anti-HBs and anti-HBc

    Measured: Anti-HBs immune response at Month 1

  3. Anti-HBs immune response in participants negative for HBsAg, anti-HBs and anti-HBc

    Measured: Anti-HBs immune response at Month 6

  4. Anti-HBs immune response in participants negative for HBsAg, anti-HBs and anti-HBc

    Measured: Anti-HBs immune response at Month 20

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing HBV vaccine (Engerix-B, recombinant hepatitis B surface antigen, 20µg/mL/vial, GlaxoSmithKline, Belgium) in people with Hepatitis B and Immune Response, run by Hui Zhuang at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 24 May 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Anti-HBs immune response in participants negative for HB sAg, anti-HBs and anti-HBc (time frame: Anti-HBs was assayed at Month 7). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 May 2013.
