About this study
Official title: A Randomized, Double-blind and Active-controlled Phase Ⅰ/Ⅲ Clinical Trial to Evaluate Immunogenicity and Safety of Rabies Vaccine (Vero Cell) for Human Use, Freeze-dried, Administered With Different Immunization Schedules in Healthy Individuals Aged 10-60 Years
To evaluate the immunogenicity and safety of different post-exposure prophylaxis (PEP) schedules of Sinovac rabies vaccine, in comparison with a marked rabies vaccinein china, in subjects aged 10-60 years old.
Read the detailed description
This clinical trial is designed as a randomized, blinded, homologous vaccine-controlled and non-inferiority trial, which consists of two parts.
Part 1 (Pilot Study):
First, 20 subjects aged 18-60 years are enrolled to receive the trial vaccine (Sinovac rabies vaccine) according to the 5-dose schedule on Days 0, 3, 7, 14 and 28. A preliminary safety assessment is conducted on Day 7 after the third dose (before the fourth dose). If the incidence of Grade 3 and above AEs does not exceed 15%, and no death or life-threatening SAE related to vaccination occurs, another 20 subjects aged 10-17 years are enrolled. A safety assessment is performed again on Day 7 after full-course vaccination. If the incidence of Grade 3 and above AEs during the entire observation period does not exceed 15%, and no death or life-threatening SAE related to vaccination occurs, the trial proceeds to Part 2. All subjects are observed for safety up to 6 months after full-course vaccination.
Part 2:
A total of 2,000 subjects are enrolled, and randomized at a 1:1:1:1 ratio, 500 in the 5-dose trial group, 500 in the 5-dose control group, 500 in the 4-dose trial group 1, and 500 in the 4-dose trial group 2. The subjects in the 5-dose trial group and the 5-dose control group receive one dose of the trial vaccine or control vaccine (a marketed rabies vaccine in China) on Days 0, 3, 7, 14 and 28, respectively. The subjects in the 4-dose trial group 1 receive one dose of the trial vaccine on Days 0, 3, 7 and 14; and the subjects in the 4-dose test group 2 receive one dose of the trial vaccine on Days 0, 3, 7 and 28.
Blood samples were collected on Day 0, 14, 28, 42, as well as 3 and 6 months after the full-course vaccination, which was for testing serum neutralizing antibodies are detected using the Rapid Fluorescent Focus Inhibition Test (RFFIT). Solicited AEs within 0-7 days after each dose, unsolicited AEs from the first dose to 30 days after full-course vaccination, and all SAEs from the first dose to 6 months after full-course vaccination are collected.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Sinovac rabies vaccine and Marketed rabies vaccine in people with Rabies (Healthy Volunteers), run by Sinovac Biotech Co., Ltd at 2 sites in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 22 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Seroconversion rate of rabies neutralizing antibodies in pre-vaccination negative subjects of each group (time frame: Day 14 after the first dose vaccination). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Jan 2026; AzTrials last refreshed its copy on 8 Nov 2026.
