NCT ID NCT06708286
First seen Aug 06, 2026 · Last updated Aug 07, 2026 · Updated 1 time
Summary
This trial evaluates a new five-component vaccine (Tdcp) designed to protect against diphtheria, tetanus, and pertussis (whooping cough). It includes about 1,820 participants aged 7 and older, who receive either the experimental vaccine or a control vaccine. The study measures how well the vaccine triggers an immune response and monitors for any side effects, aiming to see if this new formulation is safe and effective for older age groups.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Tdcp vaccine (tetanus, reduced diphtheria, and acellular pertussis, five components)
- What this could lead to
- If successful, this vaccine could offer stronger or longer-lasting protection against diphtheria, tetanus, and whooping cough for older children and adults.
- What could go wrong
- The trial is in early-to-mid stages, so the vaccine may not prove more effective than existing ones. As with any vaccine, there is a risk of side effects like injection-site reactions or fever.
