NIH Releases Mpox Research Agenda
September 17, 2024
The NIAID mpox research agenda focuses on four key objectives: increasing knowledge about the biology of all clades—also known as strains—of the virus that causes mpox, including how the virus is transmitted and how people’s immune systems respond to it; evaluating dosing regimens of current vaccines to stretch the vaccine supply and developing novel vaccine concepts; advancing existing and novel treatments, including antivirals and monoclonal antibodies; and supporting strategies for detecting the virus to facilitate clinical care and epidemiological surveillance.
NIH Awards Will Support Innovation in Syphilis Diagnostics
September 3, 2024
NIAID has awarded grants for 10 projects to improve diagnostic tools for congenital and adult syphilis—conditions currently diagnosed with a sequence of tests, each with limited precision. The Centers for Disease Control and Prevention estimates that adult and congenital syphilis cases increased by 80% and 183% respectively between 2018 and 2022—a crisis that prompted the U.S. Department of Health and Human Services (HHS) to establish a national taskforce to respond to the epidemic.
Novel Vaccine Concept Generates Immune Responses that Could Produce Multiple Types of HIV Broadly Neutralizing Antibodies
May 30, 2024
Using a combination of cutting-edge immunologic technologies, researchers have successfully stimulated animals’ immune systems to induce rare precursor B cells of a class of HIV broadly neutralizing antibodies (bNAbs). The findings, published today in Nature Immunology, are an encouraging, incremental step in developing a preventive HIV vaccine.
Introducing Peanut in Infancy Prevents Peanut Allergy into Adolescence
May 28, 2024
Feeding children peanut products regularly from infancy to age 5 years reduced the rate of peanut allergy in adolescence by 71%, even when the children ate or avoided peanut products as desired for many years. These new findings, from a study sponsored and co-funded by the National Institutes of Health’s National Institute of Allergy and Infectious Diseases (NIAID), provide conclusive evidence that achieving long-term prevention of peanut allergy is possible through early allergen consumption. The results were published today in the journal NEJM Evidence.

Statement: NIH Trial Data Underpins FDA Approval of Omalizumab for Food Allergy
February 16, 2024
FDA has approved omalizumab for the reduction of allergic reactions, including anaphylaxis, that may occur with an accidental exposure to one or more foods in adults and children aged 1 year and older with food allergy. People taking omalizumab still need to avoid exposure to foods to which they are allergic.
Switching to Vegan or Ketogenic Diet Rapidly Impacts Immune System
January 30, 2024
Researchers observed rapid and distinct immune system changes in a small study of people who switched to a vegan or a ketogenic (also called keto) diet. Scientists closely monitored various biological responses of people sequentially eating vegan and keto diets for two weeks, in random order. They found that the vegan diet prompted responses linked to innate immunity—the body’s non-specific first line of defense against pathogens—while the keto diet prompted responses associated with adaptive immunity—pathogen-specific immunity built through exposures in daily life and vaccination. Metabolic changes and shifts in the participants' microbiomes—communities of bacteria living in the gut—were also observed. More research is needed to determine if these changes are beneficial or detrimental and what effect they could have on nutritional interventions for diseases such as cancer or inflammatory conditions.
Statement: Antibody Reduces Allergic Reactions to Multiple Foods in NIH Trial
December 19, 2023
A monoclonal antibody treatment significantly increased the amounts of multiple common foods that food-allergic children and adolescents could consume without an allergic reaction, according to a planned interim analysis of an advanced clinical trial.
Study Reveals How Young Children’s Immune Systems Tame SARS-CoV-2
October 13, 2023
