The Defense Threat Reduction Agency (DTRA) has issued a Broad Agency Announcement (BAA) (HDTRA1-24-S-0002) for funding opportunities under the Biological Threat Reduction Program (BTRP), aimed at enhancing global biological threat reduction capabilities. This announcement seeks proposals for scientific studies that support and strengthen the capacity of partner nations and international organizations to detect, diagnose, and report biological threats, emphasizing biosurveillance and biosecurity initiatives. Key areas of interest include improving understanding of epidemiological factors, developing training programs, and evaluating detection methodologies. The BAA is open from April 29, 2024, to April 28, 2029, with applications accepted in phases, starting with Abstracts followed by White Papers and Full Proposals. Eligible entities include U.S. and foreign academic institutions, commercial entities, and non-profits, though certain federal entities cannot receive funds directly. The evaluation process will assess technical merit, alignment with DTRA mission goals, personnel qualifications, cost realism, and potential dual-use risks. This funding initiative seeks to foster international partnerships and enhance public health infrastructure through focused research and collaboration.
