The National Institutes of Health (NIH) has announced a funding opportunity titled "Multidisciplinary Studies of HIV/AIDS and Aging," aimed at exploring the intersection of HIV and aging. This initiative seeks to enhance understanding of the biological, clinical, and socio-behavioral aspects of aging in the context of HIV infection, while also improving strategies for testing, prevention, and treatment of HIV-related health complications. Given the increasing number of older adults living with HIV, this research is crucial for addressing public health challenges and improving healthcare delivery across diverse populations. The funding supports exploratory research under the R21 mechanism, with a maximum budget of $275,000 for two years, and applications are due between May 2025 and January 2027.
