CANADIAN CENTER FOR VACCINOLOGY (CCfV)

The Canadian Center for Vaccinology is a collaboration of Dalhousie University, the IWK Health Centre, and Nova Scotia Health.

CCfV is Canada’s first and only fully integrated collaborative vaccine research facility spanning basic science, clinical studies, and social sciences. Focused on infectious disease and vaccine research, CCfV has conducted hundreds of academic and industry-sponsored clinical trials; surveillance studies; epidemiological studies; and social science studies.

THE CHALLENGE UNIT

Located at the IWK Health Centre in Halifax, NS, the Challenge Unit is the only of it’s kind in the maritimes. In 2022, the CCfV Challenge Unit opened its doors to the first whooping cough challenge study participants in Canada. 

  • The Challenge Unit was designed to contain contagious respiratory diseases. The facility features 10 isolation rooms, each equipped with HEPA-filtered exhaust air and negative pressure to prevent the spread of any viruses or bacteria.

  • Participants stay in their own private room, equipped with a TV, high-speed internet, a desk, and an ensuite bathroom. Laundry and meal services are provided.

  • Nurses monitor participant safety and comfort 24/7 from the Unit’s own nurse’s station. Each room is set up with monitoring and diagnostic equipment to care for participants’ health.
