Opportunity Summary:

The grant opportunity titled "Understanding STI Co-Infection In At Risk and HIV Infected Adolescents and Young Adults (R21)" (Funding Opportunity Number RFA HD 17 012) is a discretionary NIH funding announcement released under HHS-NIH. It supports exploratory, early-stage research through the R21 mechanism, with the goal of improving scientific understanding of how HIV and other sexually transmitted infections (STIs) interact in adolescents and young adults, particularly at key mucosal sites where transmission and early infection dynamics are shaped. The central scientific focus is on the adolescent genital and gastrointestinal mucosa, reflecting the reality that HIV risk and acquisition are strongly influenced by mucosal biology, local immune responses, inflammation, and the presence of co-infecting pathogens.

This FOA is oriented toward research that can clarify the biological and immunological mechanisms that link STI co-infection with HIV susceptibility, transmission potential, disease progression, or local tissue-level changes in young people. By emphasizing mucosal compartments in the genital and gastrointestinal tracts, the announcement highlights areas where co-infections may alter epithelial barrier integrity, recruit or activate HIV target cells, change microbiome composition, drive cytokine and chemokine signaling, or otherwise create conditions that increase vulnerability to HIV or complicate management of HIV in those already infected. The adolescent and young adult emphasis signals interest in age-specific factors such as developmental immunology, hormonal influences, maturation of mucosal tissues, and behavioral and epidemiologic patterns that differ from adult cohorts, all of which can affect STI-HIV interactions.

In practical terms, applicants are being invited to propose research projects that generate foundational insights rather than large, definitive clinical trials, consistent with the R21 program's role in enabling innovative, high-impact exploratory work. Projects might involve studying mucosal immune responses in the presence of common STIs, characterizing how co-infections influence HIV shedding or local replication, examining inflammatory signatures in genital or GI tissues, or identifying biomarkers associated with increased acquisition risk in at-risk youth. The purpose is to fill key knowledge gaps that could later inform prevention strategies, diagnostics, microbicides, vaccines, or targeted interventions tailored to adolescents and young adults.

The opportunity lists a maximum award amount (award ceiling) of $200,000, indicating the funding cap for supported projects under this announcement. It was created and posted on June 7, 2016, with an original and current closing date of August 17, 2016, showing it was a time-limited call for proposals rather than an open-ended solicitation. The activity category is "Health, Income Security and Social Services," and the CFDA numbers associated with the opportunity are 93.865, reflecting its placement within NIH/HHS assistance programs.

Eligibility is broad and includes many types of domestic organizations capable of biomedical and public health research. Eligible applicants include state, county, city or township, and special district governments; independent school districts; public and state-controlled institutions of higher education; private institutions of higher education; federally recognized Native American tribal governments; Native American tribal organizations other than federally recognized governments; public housing authorities and Indian housing authorities; nonprofit organizations with or without 501(c)(3) status (excluding higher education institutions in those nonprofit categories as specified); for-profit organizations other than small businesses; and small businesses. An "Others" category is also included with a note to consult additional eligibility guidance in the full announcement, suggesting there may be specific clarifications or conditions for certain applicant types.

Overall, this FOA targets research that can explain, at the tissue and immune-system level, why and how STI co-infections matter for HIV risk and outcomes in adolescents and young adults. The intended impact is to strengthen the scientific base needed to design better prevention and treatment approaches that account for the unique mucosal and developmental context of youth, a population that remains disproportionately affected by STIs and faces continuing HIV vulnerability.
