The National Institutes of Health (NIH) plans to publish a Notice of Funding Opportunity (NOFO) for archiving and documenting child health and human development data sets. This funding opportunity aims to support the archiving and documentation of existing data sets within the scientific mission of the NIH's Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD). The primary goal is to enable secondary analysis of these data by the scientific community. The highest priority is given to archiving original data collected with NICHD funding. Potential applicants are encouraged to develop collaborations and projects that align with this objective. The NOFO is expected to be published in July 2024, with an anticipated application due date in October 2024. The funding opportunity will utilize the R03 activity code.
