Can a new tetanus shot offer stronger protection?
NCT ID NCT07740733
First seen Aug 03, 2026 · Last updated Aug 04, 2026 · Updated 1 time
Summary
This trial is testing a new tetanus vaccine in healthy adults aged 18 to 43. The goal is to see if the vaccine is safe and triggers a strong immune response, measured by antibody levels one month after vaccination. Participants will receive either the new vaccine or a control vaccine, and their health and immune reactions will be compared.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Tetanus toxoid (adsorbed) vaccine
- What this could lead to
- If successful, this could provide a new, safe, and effective tetanus vaccine option for adults, potentially improving protection against this serious bacterial infection.
- What could go wrong
- This is an early-to-mid-stage trial, so the vaccine may not produce a strong enough immune response or may cause unexpected side effects. Results from this trial will need confirmation in larger studies.
