Diphtheria, tetanus, and pertussis vaccine study in Japanese teens
Part of Immune system & allergy clinical trials.
This study tests a new combined vaccine against diphtheria, tetanus, and pertussis (whooping cough) in healthy Japanese teenagers aged 11–12 years. Researchers will measure how well the vaccine works and monitor for any side effects.
