New 6-in-1 shot for babies shows promise in thai trial
NCT ID NCT04429295
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested a new combination vaccine called Shan6™, which protects against six diseases (diphtheria, tetanus, whooping cough, hepatitis B, Hib, and polio) in healthy infants and toddlers in Thailand. The trial involved 460 participants and compared Shan6™ to a similar 5-in-1 vaccine given with separate polio shots. The goal was to see if Shan6™ works just as well and is safe when given alongside routine childhood vaccines.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Shan6™ (6-in-1 vaccine against diphtheria, tetanus, pertussis, hepatitis B, Hib, and polio)
- What this could lead to
- If successful, this could provide a simpler 6-in-1 vaccine option for infants, reducing the number of shots needed.
- What could go wrong
- This is a completed Phase 3 trial, so results are already in. The main risk is that the vaccine may not be as effective or safe as the current separate vaccines, but the study aims to show it is non-inferior.
