The Biomedical Advanced Research and Development Authority (BARDA) drives the development of medical countermeasures (MCMs) — technologies and products designed to prevent, prepare for, and respond to health security threats. These threats include chemical, biological, radiological, and nuclear (CBRN) hazards, pandemic influenza, and emerging infectious diseases. BARDA’s efforts encompass a wide range of innovations, including vaccines, therapeutics, diagnostics, devices, digital health tools, and enabling technologies. Developing and ensuring access to medical countermeasures for pediatric populations is a part of BARDA’s Mission and Strategic Plan to protect all members of our communities against an evolving threat landscape and to ensure that BARDA’s response accounts for all needs of all segments of the population.
