Group Intervention Description Senior group(over 65 years old)-HE Recombinant (E. Coli) Hepatitis E Vaccine Anti-HEV IgG seronegative participants over 65 years old were enrolled. Hepatitis E vaccine, containing 30mcg of HEV239 recombinant antigen adsorbed to alum adjuvant suspended in 0.5ml phosphate buffer, was given at 0, 1, 6m for three doses. Younger groups(16-65 years old) Recombinant (E. Coli) Hepatitis E Vaccine Participants aged 16-65 years old were enrolled. Hepatitis E vaccine, containing 30mcg of HEV239 recombinant antigen adsorbed to alum adjuvant suspended in 0.5ml phosphate buffer, was given at 0, 1, 6m for three doses.
- Primary Outcome Measures
Name Time Method Number of Participants with Serious and Non-Serious Adverse Events From month 0-7 Any adverse events reported within one month post each vaccination would be recorded, any serious adverse events reported throughout the study would be recorded.
- Secondary Outcome Measures
Name Time Method anti-HEV IgG seropositive rate at month 7 GMT of anti-HEV IgG 7 month after first vaccination Serum sample would be collected at month 7, and geometric mean titer of anti-HEV IgG would be tested
