National Institute of Allergy and Infectious Diseases (NIAID)

The NIAID conducts and supports basic and applied research to better understand, treat, and ultimately prevent infectious, immunologic, and allergic diseases. NIAID is part of the U.S. Department of Health and Human Services (HHS).

NIAID plays a critical role in national and global health security, particularly through its leadership in responding to emerging infectious diseases such as COVID-19, Ebola, Zika, and pandemic influenza. Its work in pandemic preparedness includes the development of vaccines, therapeutics, and diagnostics, as well as supporting infrastructure for rapid response to health threats. Its contributions have led to breakthroughs in understanding the immune system and combating diseases like HIV/AIDS, malaria, and tuberculosis.

In addition to its scientific and public health roles, NIAID significantly contributes to the U.S. economy by driving biomedical innovation and reducing the economic risks associated with infectious disease outbreaks. NIAID’s early-stage investments help de-risk critical research, enabling private sector engagement and accelerating the commercialization of life-saving products.
