About this study

Official title: Immunogenicity and Safety of Inactivated Hepatitis A Vaccine in HIV-infected People Aged 1-50 Years: A Phase IV Clinical Trial

Approximately 400 HIV-infected participants aged 1-50 years old will be recruited according to the inclusion and exclusion criteria. Among them, more than 180 participants will be recruited in the immunogenicity and safety study. Each of them will receive 2 doses of the HAV vaccine with a 6-month interval. Blood samples will be drawn before and 1 month after each dose to detect the HAV antibodies to evaluate the immunogenicity of the vaccines. Other people will be recruited in the safety study and receive at least one dose of the HAV vaccine. All the participants will report the adverse events within one month after each dose.

Read the detailed description

Approximately 400 HIV-infected participants aged 1-50 years old will be recruited in terms of inclusion and exclusion criteria. All participants will receive one dose of the hepatitis A vaccine and have their blood and urine samples collected before and after vaccination for laboratory-related indicator testing. At least 120 HAV-susceptible participants (with anti-HAV antibodies negative before vaccination) and 60 HAV-unsusceptible participants (with anti-HAV antibodies positive before vaccination) aged 18-50 years old, and an unlimited number of HIV-infected children aged 1-17 years old will be included into immunogenicity study, with rest participants included into safety study. Participants in immunogenicity study will receive the second dose of hepatitis A vaccination with a 6-month interval. Blood and urine samples will be collected 1 month, 6months (before second vaccination), and 7 months (1month after second vaccination) after the first vaccination. Participants in safety study will receive second vaccination voluntarily. Adverse events in both immunogenicity and safety study will be collected within 30 days after each dose of vaccination using smartphone mini program or diary cards.

Being tested
2 doses of HAV, At least one dose of HAV
Medical subject headings
Hepatitis A, Immunologic Deficiency Syndromes, HIV Infections

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing 2 doses of HAV and At least one dose of HAV in people with Hepatitis A and Immunodeficiency, run by LiuZhou People's Hospital 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 3 inclusion and 22 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 31 Dec 2025. 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?

Seroconversion rate of anti-HAV antibodies 30 days after 2 doses of hepatitis A vaccination among HIV-infected participants with hepatitis A susceptibility (time frame: 30 days after 2 doses of hepatitis A vaccination). The study lists 2 primary outcomes in all. 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 31 Dec 2025.
