Study Summary

The purposes of the study are to evaluate the safety and tolerability of different dose levels of recombinant herpes zoster vaccine (CHO Cells) with 2 doses at 2-month intervals in healthy subjects aged 18 years and older, and to preliminarily explore immunogenicity.

Eligibility Criteria

Inclusion

Inclusion Criteria:

  3. Be able to participate in all scheduled visits and comply with the protocolrequirements.

Exclusion

Exclusion Criteria:

  4. Female participant who is pregnant ( urine pregnancy test was positive) orbreastfeeding, or has pregnancy plans within 1 year after the last vaccination;

  5. Receipt of live vaccine within 28 days, or any other vaccine within 14 days prior tovaccination;

  6. Receipt of immunoglobulin or intravenous immunoglobulin within 3 months beforevaccination;

  7. Acute diseases or acute exacerbation of chronic disease within 3 days beforevaccination;

  8. A known allergy to any components of the study vaccine (especially allergic toaminoglycoside antibiotics), or history of severe allergy to any previousvaccination;

  9. History of convulsions, epilepsy, encephalopathy (such as congenital braindysplasia, brain trauma, brain tumor, cerebral hemorrhage, cerebral infarction,brain infection disease, nerve tissue damage caused by chemical drug poisoning,etc.) or mental illness and family history;

  10. Asplenia or functional asplenia, or splenectomy caused by any condition;

  12. Receipt of immunosuppressive therapy within 3 months before vaccination (such aslong-term use of systemic glucocorticoid ≥14 days, dose ≥2mg/kg/day or ≥20mg/dayprednisone or equivalent dose), but inhaled, intra-articular and topical steroidsare acceptable;

  13. Severe cardiovascular disease(eg. Pulmonary heart disease, Pulmonary Edema); Severeliver or kidney disease; or diabetes with complication;

  14. History of thrombocytopenia or other coagulation disorders, which may causeintramuscular injection contraindications;

  15. Abnormal blood pressure during physical examination before vaccination (systolicpressure ≥ 140 mmHg and/or diastolic pressure ≥ 90 mmHg);

  16. Abnormal and clinically significant laboratory test results as determined by theinvestigator before vaccination;

  17. Current or history of alcohol and/or drug abuse;

  18. Any condition that, in the opinion the investigator, may affect the safety of thesubject or the evaluation of the study results.

Study Description

The clinical trial will be a single-center, randomized, blind, controlled study in which two dose levels of vaccine will be tested in healthy adults aged 18 to 49 years and 50 years and older, with progression from low dose level to high dose level and younger age group to the older age group based on assessment of safety and tolerability. The younger cohort (aged 18 to 49 years) will consist of 60 subjects, 30 per dose level, and these 30 subjects will be randomized into three subgroups, including vaccine group, adjuvant group and normal saline group, with randomization ratio of 2:2:1. The older cohort (aged 50 years and older) will consist of 72 subjects, 36 per dose level, and these 36 subjects will be randomized into four subgroups, including vaccine group, adjuvant group, Shingrix® group and normal saline group, with randomization ratio of 2:2:1:1.
