Immunogenicity of Hepatitis B Vaccination in HIV-infected Adults

Phase 4
Completed
Conditions
Hepatitis B Vaccine
Interventions
Biological: 60 µg dose hepatitis B vaccine
Biological: 20 µg dose hepatitis B vaccine
Registration Number
NCT03316807
Lead Sponsor
Suping Wang
Brief Summary

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.

Detailed Description

Participants are randomized in a ratio of 1:1 into 20 µg recombinant hepatitis B vaccine group or 60µg recombinant hepatitis B vaccine group. The 20 µg group will receive three intramuscular injections of the 20 µg recombinant hepatitis B vaccine, while the 60 µg group will receive three intramuscular injections of the 60 µg dose at months 0, 1 and 6, respectively. HBsAg and anti-HBs will be tested during the study period. Adverse reactions will be recorded after vaccination.

Primary Outcome Measures

The measurements of anti-HBs antibodies were determined quantitatively by CMIA(Chemiluminescent Microparticle Immunoassay ). The accepted protective serum anti-HBs level was ≥10 mIU/ml.
