Biological: Bordetella pertussis J820 clinical trials

Establishing a Controlled Human Infection Model of Pertactin-deficient Bordetella Pertussis

This study is looking into a new way to understand whooping cough. Researchers are using a specific type of whooping cough bacteria to create a controlled infection in volunteers. This will help them learn more about how the disease affects people, especially in North America where many have been vaccinated or previously infected.
