National Institutes of Health

National Institutes of Health

The National Institutes of Health is the U.S. government’s flagship biomedical research agency, combining intramural labs and vast grant-making power to drive health science globally.
The National Institutes of Health (NIH) is a U.S. federal government body and biomedical research agency within the Department of Health and Human Services (HHS). It conducts and funds medical research, provides training, and disseminates health information, and traces its origins to a one-room Laboratory of Hygiene founded in 1887. NIH is headquartered in Bethesda, Maryland, with most of its 27 institutes and centers based there, though some are located elsewhere in the U.S. [gkekg8] Consultants track NIH because it is one of the world’s largest public funders of health research and a central node in the biomedical innovation ecosystem.

What They Do

NIH combines intramural research (labs and clinical research conducted by NIH scientists) with extensive extramural funding, awarding grants to universities, medical schools, hospitals, and other institutions across the U.S. and globally. It supports basic, translational, and clinical research on virtually all aspects of human health, from fundamental biology to disease-specific interventions, and runs major training and career-development programs for scientists and clinicians. [egf181] NIH also produces and disseminates evidence-based health information for the public and health professionals through specialized centers and websites.
Main activities and programs:
  • Intramural Research Program (IRP): NIH’s own laboratories and clinical research facilities, primarily on the Bethesda campus, conduct basic and clinical research across multiple institutes.
  • Extramural grants and contracts: Through 27 institutes and centers, NIH is “the largest public funder of biomedical research in the world,” supporting research at universities, medical centers, and other institutions. [egf181]
  • Disease- and system-specific institutes: Components such as the National Cancer Institute (NCI), National Heart, Lung, and Blood Institute (NHLBI), and National Institute of Allergy and Infectious Diseases (NIAID) focus on particular organ systems, diseases, or research domains.
  • Training and career development: NIH supports fellowships, career awards, and training grants (e.g., NRSA, K awards) for graduate students, postdocs, and early-stage investigators in biomedical and behavioral sciences. [egf181]
  • Clinical Center: The NIH Clinical Center in Bethesda is the world’s largest hospital entirely dedicated to clinical research, where investigators conduct early-stage and complex trials.
  • Public health and consumer information: NIH operates portals such as MedlinePlus (via the National Library of Medicine) and institute-specific information sites to provide accessible, science-based health information to the public and clinicians.
  • Policy and priority-setting in biomedical research: NIH develops research priorities, issues funding opportunity announcements, and coordinates large initiatives in areas such as cancer “Moonshot,” Alzheimer’s disease, and pandemic preparedness.
  • International collaboration: NIH collaborates with foreign research agencies and institutions on global health, infectious diseases, and other shared research priorities.

History and Origin Story

NIH traces its roots to the Laboratory of Hygiene established in 1887 within the Marine Hospital Service to study infectious diseases and protect public health. It evolved into the Hygienic Laboratory, then the National Institute of Health in 1930, and later expanded into the National Institutes of Health as multiple institutes were added to address cancer, heart disease, mental health, and other priority areas. Over the 20th and 21st centuries, NIH’s budget and scope grew substantially, making it a central actor in major biomedical advances, including vaccines, treatments for chronic diseases, and foundational molecular biology discoveries.
Key inflection points:
  • 1887: Establishment of the Laboratory of Hygiene within the Marine Hospital Service in Staten Island, New York, marking NIH’s origin as a federal biomedical research lab.
  • 1930: Passage of the Ransdell Act, renaming the Hygienic Laboratory as the National Institute of Health and expanding its research mandate.
  • 1944: Public Health Service Act reorganizes and expands the agency, providing a framework for future growth in research programs.
  • 1948: The National Institute of Health becomes the National Institutes of Health as multiple specialized institutes (e.g., NCI, NHLBI) are grouped under a single umbrella.
  • 1993–2000s: Major budget increases, often called the “doubling” of the NIH budget, significantly expand extramural funding and research capacity nationwide.
  • 2023: Monica Bertagnolli sworn in as NIH Director, signaling continued emphasis on cancer research, clinical trials, and translational science.

Financials and Funding

NIH is a U.S. government agency, so its funding comes primarily from congressional appropriations rather than equity or private fundraising.
  • Enacted budget: For fiscal year (FY) 2024, NIH reports an enacted budget of approximately $48.6 billion, covering its 27 institutes and centers and associated programs.
  • Extramural vs. intramural: A substantial majority of the NIH budget (roughly 80% in many recent years) goes to extramural research funding (grants, contracts, and awards) to external institutions, with the remainder supporting intramural research and operations.
  • Example institute budget: The National Institute of Allergy and Infectious Diseases (NIAID), one of NIH’s institutes, has authority to spend around $7 billion from a key federal account in the current fiscal year, illustrating the scale of individual institute budgets. [i98bt3]

Milestones and Signature Output

As a federal biomedical research agency, NIH’s “outputs” are long-running programs, landmark supported discoveries, and major initiatives rather than commercial products.
  • Polio vaccine support (1950s): NIH-funded research and trials contributed to the development and testing of the first successful polio vaccines, a cornerstone in modern vaccine history.
  • Recombinant DNA and molecular biology advances (1970s–1980s): NIH-supported scientists played central roles in recombinant DNA technology and gene cloning, enabling modern biotechnology and genetic engineering.
  • Human Genome Project (1990–2003): NIH, through the National Human Genome Research Institute (NHGRI) and partnerships, co-led the Human Genome Project, culminating in the first complete draft of the human genome.
  • Antiretroviral therapy for HIV/AIDS (1990s–2000s): NIH-funded research helped develop and refine antiretroviral drug regimens that transformed HIV infection from fatal to manageable for many patients.
  • COVID‑19 vaccines and therapeutics (2020–2021): NIH, including NIAID, supported research and clinical trials that underpinned mRNA and other COVID‑19 vaccines and treatments such as monoclonal antibodies.
  • All of Us Research Program (launched 2018): A precision-medicine cohort program aiming to enroll at least one million participants to advance individualized prevention and treatment.
  • Cancer Moonshot and oncology advances (2016–present): NIH, especially NCI, leads and funds initiatives targeting improved cancer prevention, detection, and therapies as part of the Cancer Moonshot effort.

Ecosystem and Relationships

  • U.S. Department of Health and Human Services (HHS): NIH is an operating division of HHS, reporting to the HHS Secretary and aligning with national health policy priorities.
  • U.S. Congress: NIH’s budget and statutory authority depend on congressional appropriations and authorizing legislation, making Congress a key oversight and funding body.
  • Academic and research institutions: Universities, medical schools, and hospitals are primary NIH grantees and research partners, forming a vast extramural network. [egf181]
  • Other federal health agencies: NIH collaborates with agencies such as the Centers for Disease Control and Prevention (CDC), Food and Drug Administration (FDA), and Centers for Medicare & Medicaid Services (CMS) on research and policy.
  • International research organizations: NIH works with foreign ministries of health, research councils, and global health entities (e.g., WHO) on collaborative studies and global health initiatives.
  • Patient and advocacy organizations: Disease-specific foundations and advocacy groups often partner with NIH to shape research priorities and participate in advisory structures.
