Peer-Led Clinics Are Winning Over Young People, Studies Find

Peer-Led Clinics beat standard primary care at getting young people into HIV prevention, according to two major trials whose results were unveiled as late-breaking presentations at the International Union against Sexually Transmitted Infections 2026 World Congress in Prague. The studies, run in rural South Africa, tested whether trusted peers and community-based services could succeed where conventional clinics have struggled to reach adolescents and young adults.

The trials were led by Professor Maryam Shahmanesh of the UCL Institute for Global Health, working with the Africa Health Research Institute. They focused on young people navigating sexual and reproductive health services and pre-exposure prophylaxis, or PrEP — the medication taken before exposure to prevent HIV infection. Both trials asked the same underlying question: does who delivers the service change whether young people use it?

The knowledge gaps the peers were filling are well documented. A national survey of young Italians published earlier this month found only about one in eight had strong STI knowledge, and just a third of the sexually active said they always used condoms — a reminder that information alone rarely changes behavior, as reported in our earlier coverage.

What the Two Trials Actually Tested

The first trial, called Thetha Nami, compared peer-led mobilization into community sexual health services against standard primary care delivery. Young participants guided by peer navigators — near-age outreach workers embedded in the community rather than behind a clinic desk — took up risk-informed HIV prevention at substantially higher rates. The adjusted odds ratio sat at about one point eight four, meaning the peer-led approach was associated with markedly higher uptake than business as usual.

The same study also lifted contraception use and PrEP uptake among participants, according to the university. That matters because it suggests the effect was not narrow: peers did not just move one metric, they opened a door to the broader package of sexual and reproductive health services.

The Injectable Option Changed the Math

The second trial, named LAPIS, layered choice on top of the peer model. Young people were offered a choice of prevention options, including oral PrEP and long-acting injectable cabotegravir, known as CAB-LA. The combination proved more powerful than peers alone: uptake of PrEP and post-exposure prophylaxis rose with an adjusted odds ratio of about two point one one compared with peer-led delivery of oral PrEP alone, and retention in care improved with an adjusted odds ratio of about one point three four.

Nearly two-thirds of participants chose the injectable option. That preference is the detail clinicians are likely to study longest. A daily pill demands a daily decision, discreet storage and regular refills — all friction for a teenager or young adult. An injection given at intervals removes the daily negotiation with adherence entirely.

The Caveat: More Uptake, but Infections Did Not Fall

Here is the counterpoint the researchers did not hide. Despite the gains in uptake, the first trial did not reduce the overall prevalence of transmissible HIV. The team suggested two likely reasons: poor persistence with oral PrEP, meaning many who started did not stay on it, and low rates of viral suppression among young people already living with HIV, which keeps transmission circulating even as prevention improves.

That finding reframes what Peer-Led Clinics prove. They clearly expand access — but access alone does not end transmission. The prevention tools have to be ones young people can actually stay on, and treatment for those already living with HIV has to keep pace. According to the university, the results land at a moment when some health systems are moving away from community-based delivery models, which makes evidence for the peer approach arriving now rather than later especially pointed.

For young readers, the takeaway is practical. If a daily pill has not worked for you, you are not the problem the data describes — the regimen is. Long-acting options exist and are gaining ground, and the bet that Peer-Led Clinics are making is that services built around people your own age can meet you where you are.
