The National Institutes of Health (NIH) is inviting applications for the Viral INfections in the Young Lung (VINYL) Clinical Consortium, a cooperative agreement aimed at establishing a consortium of clinical sites to conduct a comprehensive observational study on viral lower respiratory tract infections (LRTI) in children aged 0-2 years. The primary objective is to deep phenotype 1500 hospitalized infants and toddlers with viral LRTI, followed by longitudinal assessments to evaluate long-term pulmonary outcomes, including asthma, and other developmental factors. This initiative addresses critical knowledge gaps in understanding the condition and its management, with a total funding availability of up to $2.624 million for one award over a maximum project period of seven years. Interested applicants must submit their proposals by November 10, 2025, and can direct inquiries to NIH Grants Information at grantsinfo@nih.gov.
