Description
Inclusion Criteria:
- Healthy volunteers aged over 40 years (male or female).
- Able to comply with all clinical trial protocol requirements and willing to complete all the visit plan process during the whole clinical trial observation period.
- Able to understand the content of informed consent and willing to sign the informed consent.
- Able to complete the diary card independently.

- Prior history of vaccination with herpes zoster vaccine or chickenpox vaccine.
- History of allergic disease likely to be exacerbated by any component of the vaccine.
- Taking immunoglobulins and/or any blood products within the last 3 months or will receive these products during the study period.
- Taking certain pharmaceuticals to be like salicylate kind, including aspirin, and difluorosalicylic, or going to take these medicine during the study period.

- Prior administration of live vaccine in last 30 days.
- Prior administration of subunit vaccine, inactivated vaccine or allergic therapy in last 14 days.
- History of serious disease and the participation in the clinical trial is likely to increase the disease risk and interfere with the observation of clinical trial index.

- Abnormal Blood Routine and Biochemical Indexes before Inoculation (except for minor abnormalities that are not clinically significant as judged by doctors)
- Any other conditions may compromise the safety or availability of participants in the judgment of the investigator.

VZV specific serum conversion rate
Time Frame: 30 days after the vaccination
|
VZV specific serum conversion is defined as: if serum antibody titer before immunization was less than 1: 8, and antibody titer after immunization was ≥ 1: 8. Or the antibody titer before immunization was≥1:8, and the antibody titer after immunization≥4-fold increase.
