Can a new vaccine shield older kids and adults from three deadly infections?
NCT ID NCT06056050
First seen Aug 07, 2026 · Last updated Aug 07, 2026
Summary
This early-stage trial is testing an experimental vaccine designed to protect people aged 6 and older against diphtheria, tetanus, and pertussis (whooping cough). The study will enroll 180 participants to check the vaccine's safety and how well it triggers an immune response. Some participants will receive the new vaccine, while others will get a different vaccine for comparison. The goal is to see if this new option could help prevent these serious diseases in older age groups.
