US agency series: Global health R&D across the US government
Read time: 9 minutes
This six-part fact sheet series examines the contributions of US government agencies to advancing global health R&D. The series includes the US Agency for International Development, National Institutes of Health, Centers for Disease Control and Prevention, Biomedical Advanced Research and Development Authority, Department of Defense, and Food and Drug Administration.
Global Health R&D at the US Agency for International Development
What does USAID do for global health R&D?
The US Agency for International Development (USAID) supports the development, introduction, and scale-up of urgently needed drugs, vaccines, and other technologies to address unmet health needs of people in the world’s poorest places. The agency specializes in late-stage clinical research and implementation research and operates Grand Challenges to identify and advance promising health innovations from around the world.
Why is USAID’s role in global health R&D important?
USAID is the only US agency with a mandate to focus on global health and development, which means it is uniquely positioned to support product development and innovation to advance global health. The agency’s deep international footprint, combined with its in-depth understanding of community needs and culture, makes it critical for developing new health tools that are appropriate, affordable, and accessible for widespread uptake in low-resource settings.

Global Health R&D at the National Institutes of Health
What does NIH do for global health R&D?
The National Institutes of Health (NIH) excels at basic biomedical research, which unlocks early scientific discoveries that can later be translated into lifesaving global health technologies by the private sector, nonprofits, and other US agencies. NIH facilitates research for global health through in-house programs and grants to universities, nonprofits, and other organizations, and operates clinical trial networks which serve as the backbone for clinical trials taking place across America and the world.
Why is NIH’s role in global health R&D important?
NIH is the United States’ leading medical research institution and a respected, world-class scientific powerhouse. Its work to advance research for global infectious diseases, through the National Institute of Allergy and Infectious Diseases; to coordinate crosscutting HIV/AIDS research, through the Office of AIDS research; and to strengthen international research capacity, through the Fogarty International Center, forms the building blocks for future drugs, vaccines, diagnostics, and other tools that save and improve lives around the world.

COVID-19
Development of leading COVID-19 vaccines, including those from AstraZeneca/Oxford, Johnson & Johnson, and Moderna.
Global Health R&D at the US Centers for Disease Control and Prevention
What does CDC do for global health R&D?
The US Centers for Disease Control and Prevention (CDC) protects people at home and abroad through disease surveillance, rapid outbreak response, and research and development (R&D) of diagnostics, drugs, and other technologies to combat infectious diseases. Not only does CDC’s research advance new diagnostic, prevention, and surveillance technologies, it also evaluates the effectiveness of tools already in use to determine future R&D needs. CDC’s Center for Global Health and National Center for Emerging and Zoonotic Infectious Diseases leads much of the agency’s global health R&D work.
Why is CDC’s role in global health R&D important?
CDC has unique expertise and capacity to detect, track, and contain infectious disease outbreaks and develop the right technologies to advance these efforts. CDC’s work is critical to protecting Americans and people around the world from emerging epidemics, as well as monitoring the impact of current tools and global health programs to maximize future investments.

Global Health R&D at the Biomedical Advanced Research and Development Authority
What does BARDA do for global health R&D?
The Biomedical Advanced Research and Development Authority (BARDA) supports the development of vaccines, drugs, and other medical countermeasures (MCMs) to protect Americans against threats to public health, including emerging infectious diseases, pandemic influenza, and antimicrobial resistance (AMR).
Why is BARDA’s role in global health R&D important?
BARDA works with industry and other partners to bridge the “valley of death” between basic research and product development, where research and development (R&D) efforts most often fail. Through unique contracting and incentive mechanisms, BARDA’s partnerships ensure promising research is translated into urgently needed medical products by creating commercial incentives for developers that would otherwise not exist. During the COVID-19 pandemic, BARDA’s prominence and funding has grown exponentially as the agency was charged with leading the US government’s MCM R&D portfolio, demonstrating how—with sufficient, sustained funding—BARDA is uniquely equipped to advance products against a range of other global health threats.
Impact of investment
BARDA support has helped advance:
8
FDA-approved products for Ebola & Zika

ZIKA
Development of six FDA-approved diagnostics, including tests to identify infection and screen blood supplies, and several Zika vaccine candidates in development.
INFLUENZA
Strengthening manufacturing capacity in low- and middle-income countries to enable rapid production of seasonal and pandemic influenza vaccines.
Global Health R&D at the Department of Defense
What does DoD do for global health R&D?
The Department of Defense (DoD) supports research and development (R&D) for infectious diseases, antimicrobial resistance, and other health conditions that pose a risk to US national security and service members stationed abroad.
Why is DoD’s role in global health R&D important?
While DoD research first and foremost aims to protect service members overseas from local diseases, it also helps generate vaccines, drugs, and other health tools to combat diseases that are endemic in the world’s poorest places. Additionally, because DoD focuses on producing health tools for austere settings like the battlefield, the tools it advances are often well-suited for use in low-resource communities worldwide.
DoD research is unique in spanning across all stages of R&D, from basic research to late-stage clinical development and manufacturing, making it the only US agency that can single-handedly advance a single technology from early research to end-stage product.

COVID-19
Supporting ongoing development of several COVID-19 vaccine candidates, including a candidate developed at DoD labs and a temperature-stable needleless vaccine; therapeutics; and diagnostics.
CAPACITY STRENGTHENING
Operates a network of overseas labs and medical research facilities, which provide bases for infectious disease R&D, disease surveillance, and capacity-strengthening in partner nations.
Global Health R&D at the US Food and Drug Administration
What does FDA do for global health R&D?
The US Food and Drug Administration (FDA) regulates the safety and efficacy of drugs, vaccines, and other medical products marketed in the United States, which can include products also designed for use overseas. The FDA also works with international regulators in lowand middle-income countries (LMICs) to strengthen their regulatory capacity and provide technical assistance.
Why is FDA’s role in global health R&D important?
FDA approval of a product serves as a “gold standard” that can expedite regulatory review in LMICs. This effect, combined with the agency’s work in regulatory capacity strengthening, helps ensure new global health technologies are safe, effective, and accessible in low-resource settings.
Impact of investment
The FDA has approved more than 75 drugs, vaccines, and diagnostics for neglected diseases.
The FDA has 208 formal arrangements for information sharing and technical assistance with regulatory authorities in 49 countries.
