The National Institutes of Health (NIH) is offering a funding opportunity titled "Co-infection and Cancer (R01 Clinical Trial Not Allowed)" aimed at enhancing research into the connections between co-infections and cancer development. This initiative seeks to improve the mechanistic and epidemiologic understanding of infection-related cancers, particularly focusing on co-infections (excluding HIV) that may present novel opportunities for prevention and treatment, especially in understudied populations. The funding is intended for research that explores the roles of various infectious agents in cancer etiology and health disparities, with no budget cap but requiring that budgets reflect genuine project needs. Interested applicants must submit their proposals by November 5, 2025, and can reach out to NIH Grants Information at grantsinfo@nih.gov for further inquiries.
