NCT02203357

Brief Summary

The objective of this study is to evaluate the immunogenicity and Anti-HBV antibody persistence of hepatitis B vaccine with different doses and schedules. Hepatitis B vaccine with the regimens of 20μg, 0-1-6 mon and 60μg,0-1 or 0-2 mon will be administered to young adults, and the comparative immunogenicity among the three groups will be measured at 1 mon post-a series vaccination, 1- and 2-year after the first dose of the regimen. Furthermore, the safety of hepatitis B vaccine with different doses and schedules will also be evaluated.

Outcome Measures

Primary Outcomes (1)

  • Immunogenicity of Hepatitis B Vaccine With Different Doses and Schedules in Healthy Young Adults

    The measurements of anti-HBs antibodies were determined quantitatively by CMIA using the Architect i2000SR analyzer (Abbott, Chicago, IL, USA). The accepted protective serum anti-HBs level was ≥10 mIU/ml. Anti-HBs≥10 and \< 100 mIU/ml were considered low response, and anti-HBs concentrations ≥100 but \< 1000 mIU/ml were middle or moderate response, and hyper or high response was associated with an anti-HBs level ≥1000 mIU/ml. The GMCs of anti-HBs antibody will be compared among the three vaccine groups.

    one month after a series vaccination of the regimen

Secondary Outcomes (2)

  • Immunogenicity of Hepatitis B Vaccine With Different Doses and Schedules in Healthy Young Adults

    1-year after the first dose of the regimens

  • Immunogenicity of Hepatitis B Vaccine With Different Doses and Schedules in Healthy Young Adults

    2-year after the first dose of the regimens

Other Outcomes (1)

  • Safety of HBV Vaccine Determined by Number of Participants With Adverse Events

    0-3 day after the first dose of immunization
