NCT ID: NCT05099757 Not yet recruiting - Hepatitis B Vaccine Clinical Trials

The Immunogenicity and Persistence of Booster Dose With Hepatitis B Vaccine in College Students

Start date: February 20, 2022
Phase: Phase 4
Study type: Interventional

The anti-HBs produced after hepatitis B vaccination will decrease over time. College students are vaccinated with hepatitis B vaccine at birth, and their antibodies may have decreased significantly. In addition, college students are sexually active population, which has a high risk of HBV infection. It is necessary to study the anti-HBs level of college students, and analyze the strengthening immunization for this special group. This study will analyze the immunogenicity, immune persistence, and safety of booster dose of intramuscular 20 µg recombinant hepatitis B vaccines. Different booster vaccination including one-dose (0 month), two-dose (0, 1 months), or three-dose (0, 1, and 6 months) was given according to the antibody production level after booster vaccination among college students.

NCT ID: NCT03962881 Not yet recruiting - Hepatitis B Vaccine Clinical Trials

Research on Optimal Immunization Strategy of Hepatitis B Vaccine in Chronic Kidney Disease Population

Start date: May 25, 2019
Phase: Phase 4
Study type: Interventional

At present, chronic kidney disease population are vaccinated with hepatitis B vaccine according to the standard three-dose schedule immunization program, and the effect of preventing HBV infection is not ideal. This is a randomized, controlled trial. The study will evaluate the immunogenicity and persistence of 20 µg and 60 µg recombinant hepatitis B vaccine with three or four injections at months 0, 1, and 6 or 0, 1, 2, and 6 in chronic kidney disease population.

NCT ID: NCT03962816 Not yet recruiting - Hepatitis B Vaccine Clinical Trials

Immunogenicity and Persistence of Hepatitis B Vaccination in Methadone Maintenance Treatment Patients

Start date: May 26, 2019
Phase: Phase 4
Study type: Interventional

At present, Methadone Maintenance Treatment Patients of Hepatitis B Vaccination in are vaccinated with hepatitis B vaccine according to the standard three-dose schedule immunization program, and the effect of preventing HBV infection is not ideal. This is a randomized, controlled trial. The study will evaluate the immunogenicity and persistence of 20 µg and 60 µg recombinant hepatitis B vaccine with three or four injections at months 0, 1, and 6 or 0, 1,2, and 6 in Methadone Maintenance Treatment Patients

NCT ID: NCT03962803 Not yet recruiting - Hepatitis B Vaccine Clinical Trials

Immunogenicity and Persistence of Hepatitis B Vaccination in HIV-Infected Patients

Start date: June 5, 2019
Phase: Phase 4
Study type: Interventional

At present, HIV-Infected Patients of Hepatitis B Vaccination in are vaccinated with hepatitis B vaccine according to the standard three-dose schedule immunization program, and the effect of preventing HBV infection is not ideal. This is a randomized, controlled trial. The study will evaluate the immunogenicity and persistence of 20 µg and 60 µg recombinant hepatitis B vaccine with three or four injections at months 0, 1, and 6 or 0, 1,2, and 6 in HIV-Infected Patients

NCT ID: NCT03316807 Completed - Hepatitis B Vaccine Clinical Trials

Immunogenicity of Hepatitis B Vaccination in HIV-infected Adults

HIV
Start date: October 2014
Phase: Phase 4
Study type: Interventional

Uptake, adherence, and completion of vaccination among HIV-infected adults were low, and their immune function and immune response to hepatitis B vaccination were also suboptimal, indicating that the current practice of hepatitis B vaccination can't protect HIV-infected adults from HBV infection. And the persistence of immunity induced by hepatitis B vaccination remains a challenge. This is a randomized, open-label trial, conducted among HIV-infected adults with drug rehabilitation. This study will compare the immunogenicity, immune persistence, and safety of three intramuscular 20µg and 60µg recombinant hepatitis B vaccines at months 0, 1, and 6 among HIV-infected adults.

NCT ID: NCT02991599 Completed - Hepatitis B Vaccine Clinical Trials

Immunogenicity of Hepatitis B Vaccination in Methadone Maintenance Treatment Patients

Start date: October 2014
Phase: Phase 4
Study type: Interventional

This is a randomized, controlled trial. The study will evaluate the immunogenicity, immune persistence, and safety of 20 µg and 60 µg recombinant hepatitis B vaccine with three injections at months 0, 1, and 6 in methadone maintenance treatment patients.

NCT ID: NCT02963714 Completed - Hepatitis B Vaccine Clinical Trials

Immunogenicity of Hepatitis B Vaccination in Hemodialysis Patients

Start date: December 2014
Phase: Phase 4
Study type: Interventional

Intramuscular injection of 40 μg hepatitis B vaccine in a standard three-dose schedule or a four-dose schedule is recommended for hemodialysis patients. However, seroconversion rates are inadequate and persistence of immunity remains a challenge. This is a randomized, controlled trial. The study will evaluate the immunogenicity, immune persistence, and safety of 20 µg and 60 µg recombinant hepatitis B vaccine with three injections at months 0, 1, and 6 in hemodialysis patients.

NCT ID: NCT02901951 Completed - Hepatitis B Vaccine Clinical Trials

Long-term Persistence of Immunity to Hepatitis B in Adults Vaccinated With GlaxoSmithKline (GSK) Biologicals' Hepatitis B Vaccine (HBV), Engerix-B

Start date: October 11, 2016
Phase: Phase 4
Study type: Interventional

The purpose of this study is to assess the long-term protection against HBV infection in adult subjects, aged 18-40 years vaccinated with three or four doses of Engerix-B 20 to 30 years ago

NCT ID: NCT02432430 Completed - Immunization Clinical Trials
