TaipeiAges 20–36 - NCT04843852RecruitingPhase 1
Test vaccine added to hepatitis B treatment
This early-phase study tests whether a hepatitis B vaccine (with an added ingredient to boost the immune response) can safely help people with long-term hepatitis B who are already on antiviral therapy. It is mainly looking at safety and how the immune system responds.
Baltimore, MarylandAges 18 years+ - NCT06023056Recruiting
Hepatitis B vaccine after newborn surgery

Common questions
- Are there clinical trials studying Hepatitis A vaccine?
- Yes. Clin2 currently lists 17 recruiting studies that include Hepatitis A vaccine, drawn from the U.S. registry and rewritten for real people so you can see what each is testing and who it's for.
- How do I know if I qualify for a Hepatitis A vaccine trial?
- Each study lists its own eligibility criteria — rules about condition, age, and prior treatments. On every Clin2 trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Is Hepatitis A vaccine an approved treatment?
- A drug being studied in a trial may be investigational (still being tested) or already approved and being studied for a new use. Each study page explains what phase it's in. Clin2 does not provide medical advice — talk with your doctor about whether Hepatitis A vaccine or a specific trial is right for you.
