简要总结
This will be a randomized, two-arm, single-blind, parallel, placebo-controlled, multicentre clinical study planned to evaluate the immunogenicity and safety of the hepatitis E vaccine administered to healthy subjects of 16 to 65 years of age. Hepatitis B vaccine of M/s. Serum Institute of India Pvt. Ltd. which is marketed in the country for past several decades and recommended for administration through the same 3-dose schedule will be used as placebo in this study. The randomized subjects will be enrolled in either study group as per their randomization number and will be followed up in a parallel manner till the completion of the study.
Immunogenicity will be evaluated at day 0 (pre-vaccination), day 30, day 60, day 180 and day 210. Safety will be evaluated by recording the adverse events occurring during the course of the study.
