Brief Summary

The primary safety objective of this study is to assess the safety of 10 mcg recombinant hepatitis B vaccine in the Chinese health neonates. The primary immunogenicity objective is to assess the antibody response following 3 doses immunization of the 10 mcg experimental dose and 10 or 5 mcg control dose, Participants will include up to 1740 healthy neonates. This is a randomized, double-blinded, Phase III study. This study is designed to investigate the safety, reactogenicity, and immunogenicity of 10ug recombinant hepatitis B vaccine (yeast). Subjects will be stratified by the mother with positive for both HBsAg and HBeAg, positive for the surface antigen but negative for HBeAg, negative for the HBsAg and HBeAg and HBeAb and HBcAb.

  • Stratified 1: There are 180 neonates born to the mother with positive for both HBsAg and HBeAg will be randomized into two groups according to the ratio of 2:1. 120 subjects will receive the 10 mcg experimental vaccine and 60 subjects will receive 10 mcg control vaccine respectively.
  • Stratified 2: There are 360 neonates born to the mother with positive for HBsAg but negative for HBeAg will be randomized into two groups according to the ratio of 2:1. 240 subjects will receive the 10 mcg experimental vaccine and 120 subjects will receive 10 mcg control vaccine respectively.
  • Stratified 3: There are 1200 neonates born to the mother with negative for the HBsAg and HBeAg and HBeAb and HBcAb will be randomized into 3 groups. 600 of them will receive the 10mcg experimental vaccine. 300 subjects will receive 10mcg control vaccine. And the other 300 subjects will receive 5mcg control vaccine. The recombinant hepatitis B vaccine will be administered at m0, 1 and 6. Following each immunization, safety will be measured by assessment of adverse events through 30 days following each vaccination, serious adverse events and new-onset chronic medical conditions through 6 months post the final vaccination (Day 180 after last vaccination). For the immunogenicity testing will apply the chemiluminescence immunoassay on serum obtained on the day 0, 210 and 360 after born.

Outcome Measures

Primary Outcomes (2)

  • The immunogenicity of experimental recombinant HBV vaccines in healthy neonates on day 210

    Immunogenicity testing will be chemiluminescence immunoassay on serum obtained on day 210 after first dose

    on day 210 after the first dose

  • The immunogenicity of experimental recombinant HBV vaccines in healthy neonates on day 360

    Immunogenicity testing will be chemiluminescence immunoassay on serum obtained on day 360 after first dose

    on day 360 after the first dose

Secondary Outcomes (3)
