About this study
This is a randomized, observer-blind, positive-controlled study. There will be 2 treatment groups, Subjects who gave informed consent and passed the questioning screen were randomly assigned 1:1 to be immunized with 1 dose of Tetanus Vaccine, Adsorbed (TTVA) or control vaccine.
Read the detailed description
Tetanus can be prevented with tetanus toxoid-containing vaccines (TT-containing vaccines, TTCVs), which are included globally in routine immunization programs for children, and in many countries at the time of prenatal care. China eliminated neonatal tetanus in 2012, but non-neonatal tetanus remains a serious public health problem. TT vaccine was first produced in 1924 and is used as a single antigen vaccine and combination vaccine component to prevent other vaccine-preventable diseases, including diphtheria, pertussis, poliomyelitis, hepatitis B, Haemophilus influenzae type b (Hib), and other vaccine-preventable diseases. Haemophilus influenzae type b (Hib).

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing TTVA and TT in people with Tetanus, run by CanSino Biologics Inc. at 1 site 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 3 inclusion and 15 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 5 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site 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?
Positive serum conversions of anti-tetanus toxoid IgG antibodies. (time frame: 30 days after immunization). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06120751, which also lists 1 linked publication.
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 5 Aug 2026.
