About this program

The Department of Health and Human Services National Institute of Allergy and Infectious Diseases (NIAID) funds research into infectious, immunologic, and allergic diseases through CFDA 93.855, Allergy and Infectious Diseases Research, with the most recent award issued on February 11, 2028.

Grant awards under this program are active and substantial. Over the past five years, NIAID has issued between 137 and 1,986 awards annually, with 46,563 total awards spanning since 1974. The portfolio has obligated $95.17 billion in federal dollars, with total obligated dollars (including recipient matching funds) reaching $100.26 billion. The most recent award activity shows consistent funding through early 2028, indicating ongoing program viability.

The program funds research spanning infectious diseases (dengue, malaria, tuberculosis, HIV, fungal infections, arenaviruses, henipaviruses), immunologic mechanisms (germinal center dynamics, regulatory T cells, innate immunity), and allergic diseases. Representative recent awards include F31AI203216 for Wolbachia-based dengue interventions ($100,228); F31AI200193 for Zika virus congenital pathology mechanisms ($39,848); F31AI202779 for Chlamydia vaccine development ($43,714); and F31AI202526 for tuberculosis lung disease pathogenesis ($49,373). Awards fund basic mechanistic work, translational research, vaccine development, diagnostic advancement, and clinical studies.

Project Grants dominate the portfolio at 92 percent of awards (42,747 awards), with smaller shares of Block Grants (5 percent) and Cooperative Agreements (3 percent). NIAID's National Institute of Allergy and Infectious Diseases supplied the vast majority of funding—21,699 awards obligating $72.6 billion federal dollars. Additional support came from broader NIH mechanisms (23,307 awards, $16.73 billion) and other institutes including the National Institute of Neurological Disorders and Stroke ($2.65 billion), totaling 20 distinct funding agencies.

Recent awards average $40,000–$100,000 for postdoctoral fellowship training grants (F30/F31/F32 mechanism), with larger research grants reaching up to $110 million for extended projects. Federal funding and cost-sharing are roughly balanced, with combined total obligations of $100.26 billion against federal obligation of $95.17 billion.

Multiple grant opportunities are actively open. RFA-AI-28-020 (Centers for Research on Neglected Infectious Diseases) forecasts funding for parasitic neglected infectious diseases and endemic region research capacity. RFA-AI-28-015 (LAST MILE) supports effectiveness-implementation trials for HIV prevention and treatment. RFA-AI-28-017 (Partnerships for Advancing Development of Diagnostics) funds diagnostic test translation through academic-industry partnerships. Cooperative agreement-based programs including Immune Drivers of Autoimmune Disease, Asthma and Allergic Diseases Cooperative Research Centers, and HIV/AIDS Clinical Trials Networks remain under active solicitation with multiple centers and supporting infrastructure roles. PAR-27-062 (Academic Career Excellence Award K32) supports early-stage postdoctoral research and career development with rolling deadlines through July 2029.

Eligibility

Applicant eligibility

Universities, colleges, hospitals, laboratories, and other public or private nonprofit domestic institutions, including State and local units of government, and individuals are eligible to make application for grant support of research by a named principal investigator or a research career development candidate. For-profit organizations are also eligible, with the exception of NRSA. Individual NRSA awardees must be nominated and sponsored by a public or nonprofit private institution having staff and facilities appropriate to the proposed research training program. All NRSA awardees must be citizens or have been admitted to the United States for permanent residence. To be eligible, predoctoral candidates must have completed the baccalaureate degree, and postdoctoral awardees must have a professional or scientific degree (M.D., Ph.D., D.D.S., D.O., D.V.M., Sc.D., D.Eng., or equivalent domestic or foreign degree). SBIR grants can be awarded only to domestic small businesses (entities that are independently owned and operated for profit, are not dominant in the field in which research is being proposed and have no more than 500 employees). Primary employment (more than one-half time) of the principal investigator must be with the small business at the time of award and during the conduct of the proposed project. In both Phase I and Phase II, the research must be performed in the U.S. or its possessions. STTR grants can be awarded only to domestic small business concerns (entities that are independently owned and operated for profit, are not dominant in the field in which researches proposed and have no more than 500 employees) which "partner" with a research institution in cooperative research and development. At least 40 percent of the project is to be performed by the small business concern and at least 30 percent by the research institution. In both Phase I and Phase II, the research must be performed in the U.S. and its possessions. To be eligible for funding, a grant application must be approved for scientific merit and program relevance by a scientific review group and a national advisory council.

Beneficiary eligibility

Any nonprofit or for-profit organization, company, or institution engaged in biomedical research.

Uses of assistance

Beginning with fiscal year 1998, the direct costs awarded in the first year to a research project grant resulting from a competing renewal application will be limited to no more than a 20 percent increase over the direct costs awarded in the last non-competing year of that grant. Research grants provide funds for salaries, equipment, supplies, and travel. They also afford the collateral benefits of enriching the training experience of research workers. Grantees are expected to be judicious in using these funds. The application for a research grant sets forth specific terms and conditions and requires the signatures of the principal investigator and an official authorized to sign for the institution. Scientists and institutions are under an obligation to expend grant funds prudently for the purposes stated in the application and award document. For Research Career Development Awards (RCDAs) the scientists must demonstrate an outstanding research potential for independent research in the sciences related to transplantation, immunology, allergies, and immunological diseases. For National Research Service Awards (NRSAs), each individual who receives NRSA support is obligated upon termination of the award to comply with certain service and payback provisions. SBIR Phase I grants (of approximately 6-months' duration) are to establish the technical merit and feasibility of a proposed research effort that may lead to a commercial product or process. Phase II grants are for the continuation of the research initiated in Phase I and which are likely to result in commercial products or processes. Only Phase I awardees are eligible to receive Phase II support. STTR Phase I grants (normally of 1-year duration) are to determine the scientific, technical, and commercial merit and feasibility of proposed cooperative effort that has potential for commercial application. Phase II funding is based on results of research initiated in Phase I and scientific and technical merit and commercial potential of the Phase II application.

Length and time phasing of assistance

Research grant project periods average 4 years; they may not be extended beyond 7 years. (Project periods are generally composed of 1-year budget periods.) SBIR Normally, Phase I awards are for 6 months; normally, Phase II awards are for 2 years. STTR: Normally, Phase I awards are for 1 year; normally, Phase II awards are for 2 years.
