Clinical Trial Summary

This study is to evaluate lot-lot consistency of Recombinant Hepatitis E Vaccine (Escherichia Coli) Hecolin®.


Description:

This study is a mono-center, randomization, double-blind clinical trial in healthy subjects between 18 to 50. Under the premise of full informed consent, 360 subjects that meet the requirement of clinical trial in the age of 18-50 will be divided into 3 groups and injected 3 consecutive batches of Hecolin® separately. The main outcome measures are the immunogenicity evaluation and safety surveillance after inoculation according to prescribed immunization procedure.
