Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is conducted among people aged 18-50 in Dandong City, an area with a high incidence of hepatitis A in recent years. 1000 qualified pariticipants with signed informed consent will be screened for anti-HAV antibodies by collecting blood sample of 3ml. One dose of hepatitis A vaccine will be administrated to all the pariticipants. Negative anti-HAV antibodies-negative subjects will recieve the second dose of hepatitis A vaccination, and 400 of them will be randomly selected and assigned to 4 groups with different interval of vaccination(6 month, 18 months, 36 months and 60 months). Blood samples will be collected before vaccination of each dose and on 28 days after each dose of vaccination to anti-HAV antibody test. Safety data will be collected within 28 days after each vaccination with a smartphone mini-program.

immunogenicity group with vaccination interval of 6 month

Group Type OTHER

Healive (hepatitis A vacine(human diploid cell), inactivated)

Intervention Type BIOLOGICAL

The hepatitis A vaccine contains 500 SU inactivated hepatitis A virus per dose in 1mL of aluminum hydroxide solution.

For anti-HAV antibody-negative participants, two dose of hepatitis A vaccine will be given with vaccination interval of 6 month, 18 months, 36 months, and 60 months, respectively.
