[National health security agencies: facts and perspectives]

Despite major changes in its composition over the past two decades, the French health security infrastructure, currently consisting of eight agencies, has endured. This infrastructure has reinforced the French state's capacity to protect the health of its population, but it did not yet provide total protection. The future of national health agencies will depend on their ability to maintain the priority given to public health security ; to preserve credible, high-level scientific expertise ; to meet the challenges of healthcare safety ; and to organize health security at the European level.
