The National Institutes of Health (NIH) is offering a grant opportunity titled "Environmental influences on Child Health Outcomes (ECHO) Cohort Data and Biospecimen Access (X01 Clinical Trial Not Allowed)" aimed at facilitating research into maternal and child health by providing access to limited identifiable data and biospecimens from the ECHO Cohort. Applicants are required to secure X01 awards, which do not provide direct funding but ensure compliance with NIH policies while utilizing ECHO resources, and must demonstrate documented non-ECHO funding to cover all research expenses. This initiative is crucial for advancing the understanding of how environmental factors affect child health, with a focus on innovative research proposals that address early developmental exposures. Interested applicants can find more information and guidelines at the NIH grants website, with applications due by March 1, 2028, and inquiries directed to grantsinfo@nih.gov.
