Disciplines & Approaches

Disciplines and approaches include research areas that cut across multiple diseases and conditions such as basic immunology, diagnostics, therapeutics, vaccines and medical countermeasures to prevent and treat the many infectious, immune-mediated, and allergic diseases. NIAID also supports research in many Diseases & Conditions.

Antimicrobial (Drug) Resistance

Bacteria, fungi, and other microbes evolve over time and can develop resistance to antimicrobial drugs. Microbes naturally develop resistance; however, using antibiotics too often in humans and animals and in cases where antibiotics are not an appropriate treatment can make resistance develop more quickly.

Antiviral Program for Pandemics

The Antiviral Program for Pandemics (APP) aims to develop safe and effective antivirals to combat SARS-CoV-2, the virus that causes COVID-19, as well as to build sustainable platforms for targeted drug discovery and development of a robust pipeline of antivirals against viruses with pandemic potential.

Biodefense and Related Programs

NIAID supports research and development of medical countermeasures against emerging diseases and terrorist threats such as radiation exposure and chemical weapons.

Data Science

NIAID funded projects are generating large, diverse, complex data sets, and our research communities have become a data-intense enterprise. There is a critical need to transform these data into knowledge to more fully understand pathogen transmission and evolution, pathogen-host interactions, host immune response, and infectious and immune-mediated disease pathogenesis, as well as to develop new and improved diagnostics, therapeutics, and vaccines.

Genomics & Advanced Technologies

Research fields, such as genomics, proteomics, and systems biology, are creating a wealth of information about infectious and immune-mediated diseases. Through the use of advanced technologies, researchers are developing a clearer understanding of pathogens, disease, and host immunity.

Global Research

NIAID conducts and supports basic and applied research to better understand, treat, and ultimately prevent infectious, immunologic, and allergic diseases. For more than 60 years, NIAID research has led to new therapies, vaccines, diagnostic tests, and other technologies that have improved the health of millions of people in the United States and around the world.

Immune System Research

The immune system is a network of cells, tissues, and organs that work together to protect the body from infection. Although scientists have learned much about the immune system, they continue to study how the body targets invading microbes, infected cells, and tumors while ignoring healthy tissues.

Neglected Tropical Diseases

Neglected tropical diseases (NTDs), such as dengue, lymphatic filariasis, trachoma, and leishmaniasis, are called "neglected," because they generally afflict the world's poor and historically have not received as much attention as other diseases.

Vaccines stimulate the immune system to produce immune responses that protect against infection. Vaccines provide a safe, cost-effective and efficient means of preventing illness, disability and death from infectious diseases.

Vector Biology

Vectors, including insects and ticks, are capable of transmitting infectious disease pathogens among humans or between animals and humans. NIAID is committed to conducting and supporting research to better understand the biology of vectors, how they transmit diseases, and how they find and interact with human hosts, with the goal of developing new and improved ways to prevent the transmission of diseases.

Women's Health

Women face unique health problems related to many NIAID mission areas—specifically, HIV/AIDS, sexually transmitted diseases, and autoimmune disorders. Many infectious and autoimmune diseases affect female populations disproportionately.
