Phase 4
Conditions
Hepatitis A
Registration Number
NCT03231605
Lead Sponsor
China National Biotec Group Company Limited
Brief Summary

Hepatitis A is the most prevalent hepatitis which account for approximately 45% . The susceptible population is Children and adolescence, also the morbidity in adult presented rising trend in recent years. Therefore, vaccination of Hepatitis A Vaccine play an important role in National Immunisation Program(China). The aim of this experiment is to verify the effects of experimental group non-inferior than control group. The experiment methods is compared the difference of seroconversion rate and Antibody geometric mean titer (GMT)between experimental and control Hepatitis A Vaccines. In addition, evaluating the safety of two Hepatitis A Vaccines in 18-24 months Chinese Children.
