The National Institutes of Health (NIH) is announcing a funding opportunity titled "Influenza Transmission Research Consortium (P01 Clinical Trial Optional)" aimed at advancing research on the mechanisms of human-to-human transmission of seasonal influenza virus. This initiative seeks to establish a network of Influenza Transmission Research Centers that will foster collaborative, multidisciplinary teams to investigate the dynamics and drivers of influenza transmission, ultimately developing novel resources for the field of respiratory virus transmission. With an estimated total program funding of $8 million and the expectation of awarding three grants, interested applicants are encouraged to begin forming collaborations and preparing their proposals ahead of the anticipated application solicitation, which is expected to open in September 2025.
