Description of intervention(s) / exposure
Intervention: hepatitis E (HE) vaccine
The subjects were randomized and assigned to groups to administrate intramuscular injection either two 20µg HE vaccine doses (0 month, 6th month), three 10µg, 20µg, 30µg or 40 µg of HE vaccine 20 µg dose (0 month, 1st month, 6th month) respectively.
Participants received intervention treatment or control treatment will be followed-up for 1 month after the last vaccination.

Summary
Brief summary
The primary purpose of the protocol is to evaluate the safety and immunogenicity of an E.coli expressed particulate recombinant hepatitis E vaccine. The study hypothesis is that the vaccine induce significant seroconversion of IgG anti-HEV in healthy subjects, and the vaccine is tolerable for healthy adults.
