Primary | Number of Participants Whose Anti-HEV Antibody Seroconverted at One Month After The Third Dose | Measure the number of participants whose anti-HEV antibody seroconverted at month 7 to evaluate the immunogenicity of the Hepatitis E vaccine. | Month 7 | |
Primary | Geometric Mean Concentrations of Anti-HEV Antibody at One Month After The Third Dose | Measure the level of anti-HEV antibody in serum samples at month 7 to evaluate the immunogenicity of the Hepatitis E vaccine. Wu/ml:World Health Organization (WHO) units per ml. The WHO standard was used to calibrate the antibody quantitative reference. |
Month 7 | |
Secondary | Number of Participants With Changes in Liver Function Index Before and One Month After the First Dose | ALT, AST and TBIL were detected in both groups to determine the liver function of participants. The grade of ALT, AST and TBIL was determined according to the rules issued by CFDA. The fluctuations were classified into three categories: "no change" indicated no grade change; "processed" indicated a change from normal to abnormal or an increase in grade; and "improved" indicated a change from abnormal to normal or a decrease in grade or the change from abnormal to normal. | Day 0-Month 1 | |
