简要总结

A single center, randomized, double blinded phase I/IIa exploratory study to evaluate reactogenicity, safety, immunogenicity and dose-response of a new hepatitis B vaccine in human adult

详细描述

  • Objectives: To explore the most effective dose of the third generation Hepatitis B vaccine through the evaluation of reactogenicity, safety, and immunogenicity.
  • Subjects: Adults having anti-HBs antibody titers less than 10 mIU/mL after 3 previous injections of the conventional Hepatitis B vaccine.
  • Study hypothesis: The third generation Hepatitis B vaccine, containing preS antigens in addition to S antigen, has an ability to elicit faster protection and higher antibody titers than the second generation Hepatitis B vaccine in the subjects.
