Impact of Initial Influenza Exposure on Immunity in Infants (U01 Clinical Trial Not Allowed)

The purpose of this notice of funding opportunity (NOFO) is to support the establishment or continuation of longitudinal infant cohorts to determine and compare how initial and repeated natural influenza infections and/or influenza vaccinations shape infant and childhood immunity to future influenza exposures. The goal of this research is to understand how these exposures influence immune responses to subsequent influenza infections and/or vaccines and provide key information to facilitate design of durable, broadly protective influenza vaccines.

Refer to Section III. Eligibility Information in the NOFO for additional information on eligibility.Foreign Organizations/International CollaborationsNon-domestic (non-U.S.) Entities (Foreign Organizations) are eligible to apply.Non-domestic (non-U.S.) components of U.S. Organizations are eligible to apply.Foreign components, as defined in the NIH Grants Policy Statement, are allowed.NIH will no longer issue awards (i.e., new, renewal, or non-competing continuation) to domestic or foreign entities that involve foreign subawards/subcontracts. All NIH-funded research involving foreign subawards/subcontracts must be submitted in response to a NOFO that is specifically designated for funded international collaborations. This new requirement was effective, May 1, 2025.Applications involving foreign subawards/subcontracts submitted in response to this NOFO will be deemed noncompliant and will not be considered for funding. This policy applies to all monetary international collaborations resulting in foreign subawards/subcontracts, however, it does not preclude unfunded international collaborations or foreign components, funding for foreign consultants, or procurement of unique equipment or supplies from foreign vendors.
