Reliability of HIV viral load tests for CAB-LA PrEP questioned in new study

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.

Long-acting injectable CAB-LA safe for HIV PrEP during pregnancy, study finds

Long-acting injectable cabotegravir (CAB-LA) was safe and well tolerated as HIV pre-exposure prophylaxis (PrEP) before and during pregnancy in the follow-up phase of a global study among cisgender women.

PrEPVacc HIV vaccine trial shows no reduction in infections

The results of the PrEPVacc HIV vaccine trial conducted in Eastern and Southern Africa, which ran between 2020 and 2024, show conclusively that neither of the two experimental vaccine regimens tested reduced HIV infections among the study population.

Elite Controllers: Do their genomes hold the key to curing HIV?

Although South Africa has the largest number of people living with HIV worldwide, strides have been made in controlling the epidemic, especially in the reduction of HIV incidence, testing, and treatment. Equipped with MGI’s advanced sequencing tools and technologies, researchers from the South African Medical Research Council (SAMRC) and University of KwaZulu-Natal (UKZN) are inching closer to finding the answer to the natural control of HIV infection, leading to improved health outcomes and quality of life amongst South Africans.

Novel antiviral protein SAMD9L blocks HIV-1 and other lentiviruses

Researchers discovered that interferon-stimulated SAMD9L restricts HIV-1 and other lentiviruses by inhibiting viral translation and endosomal trafficking, while SAMD9 enhances HIV-1 replication.

New HIV test targets neglected strains in global cure hunt

A multinational team led by Weill Cornell Medicine investigators developed a test that will help measure the persistence of HIV in people affected by viral strains found predominantly in Africa-;a vital tool in the search for an HIV cure that will benefit patients around the world.

Innovative HIV vaccine approaches yield potential for broad protection against viral strains

A major challenge in developing a vaccine for HIV is that the virus mutates fast-;very fast. Although a person initially becomes infected with one or a few HIV strains, the virus replicates and mutates quickly, resulting in a "swarm" of viral strains existing in a single body.

Lenacapavir: A breakthrough in long-acting HIV prevention for cisgender women

The injectable antiretroviral drug lenacapavir was safe and 100% effective as long-acting HIV pre-exposure prophylaxis (PrEP) among cisgender women in a Phase 3 clinical trial, according to top-line findings released by Gilead Sciences, Inc., the study sponsor.

Breast milk's secret weapon against RSV revealed in new study

Researchers explored how human milk oligosaccharides (HMOs) protect infants from respiratory syncytial virus (RSV), suggesting that these components in breast milk may prevent or reduce the severity of RSV infections through multiple mechanisms including gut microbiome modulation and direct antiviral actions.

Unveiling the key role of RNA modification in HIV-1 survival and replication

A chemical modification in the HIV-1 RNA genome whose function has been a matter of scientific debate is now confirmed to be key to the virus's ability to survive and thrive after infecting host cells, a new study has found.
