The National Institutes of Health (NIH) has announced a funding opportunity titled "Molecular Mechanisms of Combination Adjuvants (MMCA) (R01 Clinical Trial Not Allowed)" aimed at supporting research into the mechanisms of action of combined vaccine adjuvants. This initiative seeks to enhance the understanding of how multiple adjuvants work together to improve immune responses, particularly for vulnerable populations such as neonates and older adults. The NIH plans to allocate approximately $2.56 million to fund 4-6 awards, with annual budget requests expected to be under $500,000, and applications are due by June 11, 2025. Interested applicants can find more information and guidelines at the NIH grants website or contact NIH Grants Information at grantsinfo@nih.gov for further inquiries.
