Primary Outcome Measures :
  1. Seroconversion rate and GMC of anti-HEV IgG at Month 7. [ Time Frame: 7 months ]
    Measure anti-HEV IgG in serum samples at 7 month to evaluate the immunogenicity of the Hepatitis E vaccine.


Secondary Outcome Measures :
  1. Adverse reactions/events of all subjects [ Time Frame: up to 7 months ]
    Measure solicited local adverse reactions within 7 days after each vaccination; Measure solicited systematic adverse reactions within 7 days after each vaccination; Measure unsolicited adverse reactions within 30 days after vaccination; Measure serious adverse events occurred throughout the study.
