NIH Research Identifies Opportunities to Improve Future HIV Vaccine Candidates
December 14, 2023
An effective HIV vaccine may need to prompt strong responses from immune cells called CD8+ T cells to protect people from acquiring HIV, according to a new study from researchers at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, and colleagues. The study findings, appearing in Science, draw comparisons between the immune system activity of past HIV vaccine study participants and people with HIV who naturally keep the virus from replicating even in the absence of antiretroviral therapy (ART).
Combination Anti-HIV Antibody Infusions Suppress Virus for Prolonged Period
June 1, 2022
Individuals with HIV who began taking antiretroviral therapy (ART) in the early stages of infection achieved a lengthy period of HIV suppression without ART after receiving two broadly neutralizing anti-HIV antibodies (bNAbs), according to a small study published today in the journal Nature. The findings suggest that combination bNAb therapy might offer a future alternative to daily ART for people living with HIV.
Experimental mRNA HIV Vaccine Safe, Shows Promise in Animals
December 9, 2021

NIH Researchers Identify How Two People Controlled HIV After Stopping Treatment
October 28, 2021
Research led by scientists at the National Institutes of Health has identified two distinct ways that people with HIV can control the virus for an extended period after stopping antiretroviral therapy (ART) under medical supervision. This information could inform efforts to develop new tools to help people with HIV put the virus into remission without taking lifelong medication, which can have long-term side-effects.
An Isolated Viral Load Test May Generate False Positive Results for People Using Long-Acting PrEP
July 23, 2024
A single laboratory-based HIV viral load test used by U.S. clinicians who provide people with long-acting, injectable cabotegravir (CAB-LA) HIV pre-exposure prophylaxis (PrEP) did not reliably detect HIV in a multi-country study. In the study, a single positive viral load test was frequently found to be a false positive result. However, a second viral load test with a new blood sample was able to distinguish true positive results from false positive results for all participants whose initial viral load test was positive.

Experimental HIV Vaccine Regimen Safe but Ineffective, NIH Study Finds
January 18, 2023
An investigational HIV vaccine regimen tested among men who have sex with men (MSM) and transgender people was safe but did not provide protection against HIV acquisition, an independent data and safety monitoring board (DSMB) has determined. The HPX3002/HVTN 706, or “Mosaico,” Phase 3 clinical trial began in 2019 and involved 3,900 volunteers ages 18 to 60 years in Europe, North America and South America.
NIH-Developed HIV Antibodies Protect Animals in Proof-of-Concept Study
January 17, 2024
Three different HIV antibodies each independently protected monkeys from acquiring simian-HIV (SHIV) in a placebo-controlled proof-of-concept study intended to inform development of a preventive HIV vaccine for people. The antibodies—a human broadly neutralizing antibody and two antibodies isolated from previously vaccinated monkeys—target the fusion peptide, a site on an HIV surface protein that helps the virus fuse with and enter cells.
Statement—NIH Celebrates FDA Approval of Long-Acting Injectable Drug for HIV Prevention
December 21, 2021
