The world has been searching for an HIV cure for decades, and a recent study in South Africa is offering new hope. A groundbreaking Phase IIa clinical trial has shown that 25% of the women who participated remained off antiretroviral therapy (ART) for 43 weeks without their HIV rebounding. This is a major step forward in the fight against HIV/AIDS and raises new questions about whether a functional cure is on the horizon.

A New Breakthrough in HIV Treatment
For years, scientists have asked, “Does HIV have a cure?” The answer has always been no – at least, not yet. But South African researchers are now closer than ever to changing that answer. The latest HIV cure trial, conducted with a group of women from the Females Rising through Education, Support, and Health (FRESH) cohort, has delivered results that experts are calling remarkable.
The trial involved 20 women living with HIV who had been on suppressive ART for at least 12 months. Each participant was sensitive to at least one broadly neutralizing antibody (bNAb). The treatment regimen combined up to 10 doses of the toll-like receptor 7 (TLR7) agonist vesatolimod (VES) with intravenous infusions of two bNAbs: VRC07-523LS and CAP256V2LS. This unique approach aimed to boost the immune system’s ability to control the virus without daily medication.

Why Is This Trial So Important?
HIV has always been one of the most challenging viruses to cure because it hides in the body, making it difficult for the immune system to detect and destroy. Traditional treatments involve antiretroviral therapy (ART), which helps control the virus but does not eliminate it. Patients must take ART for life to prevent the virus from multiplying.
This trial is groundbreaking for several reasons:
- It is the first to show that a significant portion of participants could control the virus without daily medication.
- It focuses on women, who are often underrepresented in HIV cure research.
- It provides valuable insight into how the immune system can be trained to fight HIV more effectively.
How Does This Potential HIV Cure Work?
Participants in the study entered an analytical treatment interruption (ATI) period on day 35 after treatment began. This allowed researchers to observe the rebound of the virus and the timing of ART reinitiation. The participants remained off ART until day 336 or until specific virologic thresholds were met.
The results were promising:
- Five participants (25%) completed the 43-week ATI without needing to restart ART.
- Two of these individuals maintained viral loads below 50 copies/mL, which suggests strong immune control over the virus.
- Eight participants showed partial virologic control, with fluctuating viral loads that may indicate immune-mediated viral suppression.
- Fourteen participants had to resume ART, while one remained in the ATI phase at the end of the study.
Although one participant discontinued VES due to mild cytokine release syndrome, the rest tolerated the treatment well, with only mild, short-term infusion-related reactions.
What This Means for the Future of HIV Cure Research
This trial is one of many happening around the world to explore different strategies for curing HIV. While a complete cure is not yet available, scientists believe we are getting closer. Here’s what this means for the future:
- More Research on Functional Cures – Scientists are learning how to train the immune system to control HIV without ART.
- Potential for Long-Term Remission – Some people might be able to live without daily medication in the near future.
- Hope for an HIV Cure – Studies like this provide valuable information that could lead to a permanent cure.
Could We See an HIV Cure by 2025?
Many people ask, “How to cure HIV in 15 days?” Unfortunately, there is no treatment available yet that can eliminate the virus in such a short time. However, research like the South African trial is showing us that a cure could be closer than we think. Some experts believe that by 2025, we could have treatments that allow people to live ART-free for longer periods, and eventually, a complete cure may be discovered.
The Challenges Ahead
While this study is promising, there are still many challenges to overcome:
- Long-Term Effectiveness – Scientists need to determine whether the 25% of women who remained ART-free can sustain this control for years.
- Larger Studies Needed – More trials with diverse groups of people are necessary to confirm these results.
- Accessibility – If a cure is found, it must be affordable and available to people worldwide, especially in high-burden areas like sub-Saharan Africa.

What Can People Living with HIV Do Right Now?
While the world waits for an HIV cure, there are steps people living with HIV can take to stay healthy:
- Stay on ART – If you are on antiretroviral therapy, it’s crucial to continue taking your medication as prescribed.
- Follow HIV Cure Research – Stay informed about new treatments and clinical trials.
- Practice a Healthy Lifestyle – Eating well, exercising, and reducing stress can support your immune system.
Conclusion:
The South African HIV cure trial is a sign of real progress. For the first time, a quarter of participants have remained ART-free for nearly a year without the virus rebounding. While we’re not there yet, this study brings us one step closer to answering the question: “Does HIV have a cure?”
With continued research, funding, and global collaboration, we may soon see a world where people living with HIV no longer need daily medication – or even better, where HIV is completely cured. Until then, staying informed and supporting scientific advancements is key to making this dream a reality.
The future is hopeful, and the search for a cure continues.
