World TB Day 2023 – ‘Yes! We Can End TB!’
March 24, 2023
Each year, on March 24, the National Institute of Allergy and Infectious Diseases (NIAID), part of the NIH, joins people and organizations from around the globe in marking World Tuberculosis Day. On this day, more than 140 years ago, Dr. Robert Koch announced his discovery that most human tuberculosis (TB) is caused by the bacterium Mycobacterium tuberculosis (Mtb). Although our scientific insight into this disease has grown over the past century, TB is still one of the deadliest infectious diseases on the planet. Today, NIAID joins the world in a message of hope: “Yes!
The Antiviral Tecovirimat is Safe but Did Not Improve Clade I Mpox Resolution in Democratic Republic of the Congo
August 15, 2024
The antiviral drug tecovirimat did not reduce the duration of mpox lesions among children and adults with clade I mpox in the Democratic Republic of the Congo (DRC), based on an initial analysis of data from a randomized, placebo-controlled trial. However, the study’s 1.7% overall mortality among enrollees, regardless of whether they received the drug or not, was much lower than the mpox mortality of 3.6% or higher reported among all cases in the DRC. This shows that better outcomes among people with mpox can be achieved when they are hospitalized and provided high-quality supportive care.

Experimental mRNA HIV Vaccine Safe, Shows Promise in Animals
December 9, 2021
An experimental HIV vaccine based on mRNA—the same platform technology used in two highly effective COVID-19 vaccines—shows promise in mice and non-human primates, according to scientists at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. Their results, published in Nature Medicine, show that the novel vaccine was safe and prompted desired antibody and cellular immune responses against an HIV-like virus.

HIV Vaccine Candidate Does Not Sufficiently Protect Women Against HIV Infection
August 31, 2021
An investigational HIV vaccine tested in the “Imbokodo” clinical trial conducted in sub-Saharan Africa posed no safety concerns but did not provide sufficient protection against HIV infection, according to a primary analysis of the study data. The Phase 2b proof-of-concept study, which began in November 2017, enrolled 2,637 women ages 18 to 35 years from five countries.

Existing Drug Shows Promise as Treatment for Rare Genetic Disorder
May 30, 2024
A drug approved to treat certain autoimmune diseases and cancers successfully alleviated symptoms of a rare genetic syndrome called autoimmune polyendocrine syndrome type 1 (APS-1). Researchers identified the treatment based on their discovery that the syndrome is linked to elevated levels of interferon-gamma (IFN-gamma), a protein involved in immune system responses, providing new insights into the role of IFN-gamma in autoimmunity.

NIH Launches Clinical Trial of Epstein-Barr Virus Vaccine
May 6, 2022
The National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, has launched an early-stage clinical trial to evaluate an investigational preventative vaccine for Epstein-Barr virus (EBV). EBV is the primary cause of infectious mononucleosis and is associated with certain cancers and autoimmune diseases. The Phase 1 study, which will be conducted at the NIH Clinical Center in Bethesda, Maryland, is one of only two studies to test an investigational EBV vaccine in more than a decade.

Vaccine-Induced Immune Response to Omicron Wanes Substantially Over Time
July 19, 2022
Although COVID-19 booster vaccinations in adults elicit high levels of neutralizing antibodies against the Omicron variant of SARS-CoV-2, antibody levels decrease substantially within 3 months, according to new clinical trial data. The findings, published today in Cell Reports Medicine, are from a study sponsored by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. The trial was led by NIAID’s Infectious Diseases Clinical Research Consortium.

NIH Scientists Use Human Cerebral Organoid to Test Drug for Deadly Brain Disease
March 9, 2021

NIAID Discovery Leads to Novel Probiotic for Eczema
June 26, 2024
NIAID research has led to the availability of a new over-the-counter topical eczema probiotic. The probiotic is based on the discovery by scientists at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, that bacteria present on healthy skin called Roseomonas mucosa can safely relieve eczema symptoms in adults and children.

Mix-and-Match Trial Finds Additional Dose of COVID-19 Vaccine Safe, Immunogenic
January 26, 2022
In adults who had previously received a full regimen of any of three COVID-19 vaccines granted Emergency Use Authorization (EUA) or approved by the Food and Drug Administration (FDA), an additional booster dose of any of these vaccines was safe and prompted an immune response, according to preliminary clinical trial results reported in The New England Journal of Medicine. The findings served as the basis for recommendations by the FDA and the Centers for Disease Control and Prevention in late fall 2021 to permit mix-and-match COVID-19 booster vaccinations in the United States.
