Can HIV be cured? New study shows a promising path to a functional cure

Can HIV be controlled without daily medication? A small study found that immunotherapy helped several participants maintain low viral loads even after stopping ART. (Image: Pexels)

ART has played a key role in HIV treatment for over four decades, allowing millions to lead long, healthy lives. However, ART doesn't cure HIV; patients must take it for the rest of their lives. A recent small study has given new hope that the body's immune system might learn to control HIV without ongoing medication.

What the new study found

Researchers at the University of California, San Francisco (UCSF) conducted a controlled “treatment interruption” study involving 10 people living with HIV. Before stopping ART, study participants got an experimental combo treatment that included:

• An HIV vaccine to train the immune system
• Broadly neutralising antibodies (bNAbs) that can target multiple HIV strains
• Drugs to activate dormant HIV in the body

After this treatment, participants stopped taking ART, and doctors monitored them closely.

Surprisingly, seven out of the ten participants maintained low or undetectable viral loads for several months without medication. One person showed sustained control for over 18 months. In others, the virus rebounded — but much slower than typically seen after stopping ART.

Researchers call this outcome a potential step toward a “functional cure” — where the virus isn’t fully eradicated, but remains suppressed naturally by the immune system.

Why this matters

Daily ART works well but comes with challenges: long-term adherence, cost, side effects, and social stigma. A treatment that lets people take breaks from daily pills without the virus coming back could boost quality of life.

According to experts, these immune-boosting treatments might one day lower healthcare costs and pave the way to lasting recovery in areas where HIV is widespread.

But there are major limitations

Despite the excitement, scientists stress that the findings must be viewed cautiously:

• The trial included only 10 participants
• There was no control group
• HIV remains notorious for hiding in latent viral reservoirs that are extremely difficult to eliminate

Researchers still don’t understand why some participants responded far better than others. More work is needed to refine the therapy, increase consistency, and ensure long-term safety.

What comes next

Larger clinical trials are already being planned to validate these results. Scientists also hope to personalise immunotherapy approaches by studying genetic, viral and immune factors that influence response.

Globally, parallel efforts — including gene-editing technologies, stem-cell-based approaches and methods to flush out latent HIV — continue to push the field forward.

For now, this study doesn’t signal a cure — but it does offer an encouraging glimpse of what future HIV treatment could look like: less medication, stronger immunity, and a step closer to long-term remission.

FAQs on immunotherapy for HIV

What is immunotherapy for HIV?

Immunotherapy for HIV involves treatments that boost or restore the immune system’s ability to control or eliminate HIV.

How does immunotherapy differ from ART?

While ART requires daily medication to suppress the virus, immunotherapy aims to train the immune system to control HIV without the need for continuous medication.

Is immunotherapy a cure for HIV?

Currently, immunotherapy is not a cure for HIV. However, it shows promise in achieving a “functional cure,” where the virus is not eradicated but remains suppressed by the immune system.

What are the potential benefits of immunotherapy for HIV?

Immunotherapy could reduce the need for daily medication, lower healthcare costs, improve quality of life, and decrease side effects and social stigma associated with lifelong ART.

Are there any risks or limitations to HIV immunotherapy?

Immunotherapy for HIV is still experimental and comes with risks and limitations, including inconsistent responses among patients, difficulty in eliminating latent viral reservoirs, and the need for more research to ensure long-term safety and effectiveness.
