Rabies vaccine batch check: will it pass the test?
NCT ID NCT07416110
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether three different batches of a rabies vaccine work the same way and are safe. It involves 912 healthy adults aged 18 to 45. The goal is to make sure every batch produces a strong immune response.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- rabies vaccine (Vero cell, freeze-dried)
- What this could lead to
- If successful, this could confirm that the vaccine is consistently effective and safe, supporting its wider use to prevent rabies after exposure.
- What could go wrong
- This trial only checks consistency between batches, not whether the vaccine prevents rabies itself. It is also in healthy volunteers, so results may not apply to people with weakened immune systems.
Why investors are watching
Sinovac Biotech is running a Phase IIIb trial with 912 healthy adults aged 18 to 45 to check that three consecutive production batches of its rabies vaccine produce a consistent immune response. For a small-cap company, this readout matters because it tests whether the vaccine can be made reliably at commercial scale, a step needed for regulatory approval and broader market use.
If it works: A positive result could support Sinovac's application to sell the rabies vaccine more widely, potentially adding a steady revenue source from a vaccine with global demand. It could also strengthen the company's reputation for manufacturing quality.
If it fails: If the trial fails to show consistency between batches, or if safety problems appear, regulators may delay or reject the vaccine, and Sinovac would need to fix its manufacturing process. Clinical trials often fail, so investors should expect that outcome as a real possibility.

Inclusion Criteria: 1. Participants are able to understand and voluntarily sign the Informed Consent Form; 2. Able to provide legal identity documents; 3. Age 18 to 45 years; 4. Stable health status (defined as stable underlying disease status within 3 months prior to enrollment, i.e., no change in original treatment or hospitalization due to disorder aggravation); 5. Female participants of childbearing potential must voluntarily adopt effective contraception measures from the signing of the Informed Consent Form until 2 months after the last dose of the investigational Vaccine in the primary immunization series, and have no plans to donate eggs; male participants have no plans to donate sperm; female participants of childbearing potential must also have adopted effective contraception measures within 2 weeks prior to Enrollment. Exclusion Criteria: 1. For subjects with pyrexia on the scheduled vaccination day, axillary temperature \>37.3℃ before vaccination; 2. Previous use of anti-Rabies Passive immunization preparations (including but not limited to equine-derived Immunoglobulin ERIG, human-derived Immunoglobulins HRIG, and rabies monoclonal antibody preparations, etc.) or previous Vaccination with human Rabies Vaccine; 3. Individuals with mammalian animal bites/scratches (e.g., dog/cat) and broken skin (i.e., Category II or higher exposure) within the past year.; 4. Female participants who are lactating or pregnant (including those with a positive urine pregnancy test). 5. Known allergy to any component of the trial Vaccine, or a history of severe allergies (such as anaphylactic shock, allergic laryngeal edema, allergic purpura, severe urticarial rash, dyspnea, angioneurotic edema, etc.); 6. Presence of autoimmune diseases, immunodeficiency diseases (including but not limited to systemic lupus erythematosus, ankylosing spondylitis, asplenia, functional asplenia, splenectomy); 7. Poorly controlled chronic diseases or history of severe diseases, including but not limited to cardiovascular disorders (e.g., uncontrolled hypertension: systolic blood pressure ≥140 mmHg and/or diastolic blood pressure ≥90 mmHg), metabolic diseases (e.g., poorly controlled diabetes), hematological diseases, liver and kidney diseases, digestive system diseases, respiratory system disorders, history of major organ transplantation, malignant neoplasms within the past five years, or any other diseases or physiological conditions that the investigator believes may interfere with the trial results. 8. History of encephalopathy with significant recovered with sequelae or dysfunction, or current encephalopathy (e.g., congenital cerebral dysgenesis, brain trauma, brain tumor, cerebral hemorrhage, cerebral infarct, brain infection, chemical drug poisoning, etc., causing brain nerve tissue injury); history of convulsions, epilepsy, mental illness or family history of mental illness, or other serious neurological diseases; 9. Presence of physician-diagnosed coagulation abnormalities (e.g., coagulation factor deficiency, coagulation disorders, platelet abnormalities); 10. Systemic immunosuppressive agents or other immunomodulatory therapy for ≥14 days within the past 6 months (prednisone ≥20 mg/day or ≥2 mg/(kg·day), or equivalent), cytotoxic therapy, or planned receipt of such therapy during the study period; 11. Received Immunoglobulins or other blood products within 3 months prior to receiving the investigational Vaccine, or plans to receive such treatment during the study period; 12. Received other Study Drug or Vaccine within the past 30 days, or plans to receive such drug or Vaccine during the study period; 13. Within 14 days prior to receiving the investigational vaccine, vaccination with a live attenuated vaccine, or within 7 days, vaccination with subunit, inactivated, or other types of vaccines. 14. Currently participating in other Vaccine or drug Clinical Studies, or planning to participate in other Clinical Trials during the study period; 15. Subjects with skin injuries, inflammation, ulcers, skin rash, or scars at the Vaccination site that may interfere with dosing or the observation of local reactions. 16. Within 3 days prior to vaccination, any acute disease or acute exacerbation of a chronic disease, or known or suspected active infection; 17. Based on the Investigator's judgment, the participant has any other discomfort or factors suitable for participating in the clinical trial.
