Lima, Peru — Think about a world the place an HIV prevention technique lasts for six months, providing safety with out the every day problem of taking a capsule. This might quickly be a actuality as new long-acting HIV prevention instruments transfer via the analysis pipeline.
These prevention instruments are designed to remodel the struggle in opposition to HIV, significantly in locations the place every day oral pre-exposure prophylaxis (PrEP) has been troublesome to implement.
Professor Nelly Mugo from the Kenya Medical Analysis Institute (KEMRI) considers what would occur if “all faculty college students, all youngsters (have been) on these merchandise”.
“… as a result of give it some thought, that’s the time when most individuals get HIV. We have to bridge folks via this era of their life, when their hormones are raging, once they’re settling into themselves, once they’re settling down in life, they’ll settle into their sexual lives in a safer means,” Mugo says.
“We all know the height interval that individuals get HIV is eighteen to 24 proper? After which for some at 30 and some extra later in life. So when you have this product that lasts for lengthy durations of interval you may defend folks. The much less HIV we’ve got within the inhabitants, the decrease the danger of getting an infection,” the KEMRI scientist and medical physician says.
Breaking New Floor with Lengthy-Performing HIV Prevention
Lengthy-acting HIV prevention options are gaining traction as revolutionary alternate options to every day drugs, with merchandise just like the dapivirine vaginal ring, the lenacapavir injection, and CAB-LA main the cost.
In contrast to oral PrEP , which requires every day adherence, the dapivirine ring is an intravaginal gadget that may be positioned within the cervix and offers safety for a complete month.
This topical product is designed to ship medicine instantly the place it is wanted, minimizing systemic absorption and enhancing security. Regardless of its approval, the ring remains to be not broadly adopted in lots of international locations, partly as a consequence of unfamiliarity with such well being merchandise and cultural hesitations surrounding their use.
Nevertheless, early adopters have reported constructive experiences, sparking hope for broader acceptance as consciousness will increase.
The dapivirine ring is a versatile silicone ring inserted into the vagina, the place it releases HIV-preventing medicine regionally for a month. It has been confirmed as protected and efficient however faces cultural and logistical challenges in its adoption.
“There is a contraceptive ring out there, but it surely’s by no means actually come to Africa as a result of it’s kind of dearer, and in addition individuals are just a little bit shy about introducing issues of their personal components, however those that use it actually prefer it. So it is my hope, as we girls change into extra aware of that ring, that we’ll use it extra typically,” says Mugo.
The “good factor” about topical merchandise, she says, is that they’re “very protected: “… as a result of you aren’t getting numerous the drug your physique in your blood system, the drug stays within the space the place the danger occurs, within the vaginal canal”.
Different improvements on this space, for instance Matrix’s Quick Dissolving Vaginal Insert and Twin-Goal Vaginal Movie, are nonetheless underneath investigation. These skinny movies dissolve upon insertion and supply a promising possibility for month-to-month safety with out elimination.
One other promising long-acting HIV prevention possibility is the CAB-LA injection, a type of PrEP, administered each two months by healthcare suppliers. It has proven nice potential in group research, with many expressing enthusiasm for an answer that eliminates the necessity for every day medicine.
Moreover, lenacapavir, a first-in-class antiretroviral, gives six months of safety and is present process regulatory processes. Lenacapavir is indicated for adults with multidrug-resistant HIV-1 strains, the place current therapies have failed as a consequence of resistance or intolerance.
This subcutaneous injection – administered underneath the pores and skin – although nonetheless in early analysis, has the potential to drastically change HIV prevention by providing even longer-term safety.
“… lenacapavir just isn’t but out there, as a result of it is solely in July that we had the outcomes introduced of PURPOSE 1, and I believe final month on this convention, we heard in regards to the outcomes of PURPOSE 2. So first outcomes was amongst ladies, and now it is amongst homosexual populations,” says Mugo.
Whereas its excessive price poses challenges for accessibility, efforts are underway to transition it to a extra inexpensive generic possibility by 2026. These long-acting merchandise are paving the best way for a more practical and manageable method to HIV prevention, significantly in areas the place adherence to every day medicine stays a major barrier.
“So these two lengthy lively merchandise (lenacapavir and CAB-LA) nonetheless should be given by healthcare suppliers. The ring you may insert your self – as soon as a lady is taught find out how to do it, it is easy to do,” says Mugo.
Making certain Entry to These Who Want It Most
Whereas these long-acting instruments maintain nice promise, one of many greatest challenges is guaranteeing that they attain the communities that want them probably the most, significantly in rural and underserved areas. It will require a coordinated effort amongst healthcare suppliers, researchers, governments, and native communities, Mugo says.
“There’s no single group that may do that alone,” says Mugo. “KEMRI is concerned within the analysis, however supply is the duty of packages like LVCT Well being, the Ministry of Well being, and different companions.”
In Kenya, LVCT Well being, an NGO recognized for implementing well being programmes at scale, has already launched the dapivirine ring, partaking with group members, policymakers, and healthcare suppliers to construct consciousness and acceptance of the product.
Nevertheless, the problem of entry isn’t just logistical—it’s additionally cultural.
“Introducing new merchandise, particularly these involving sexual well being, might be met with resistance, significantly in conservative communities,” says Mugo.
“Effectively, , when issues are new, folks hesitate, whenever you’re introducing one thing that is unfamiliar, and their male companions additionally would want to find out about it. The ring can be utilized discreetly, however ladies are involved about utilizing it with out their associate’s information … For some folks, it is good, they wish to use a product with out having to speak in confidence to their companions.”
The Function of Coverage and Regulation
One other barrier to the widespread adoption of those long-acting HIV prevention instruments is the regulatory setting. In Kenya, for instance, the approval of CAB-LA by the Kenya Pharmacy and Poisons Board took a very long time to be authorised for analysis functions.
“We have to streamline the regulatory course of, so these merchandise can transfer extra rapidly via the pipeline and change into out there to those that want them,” says Mugo.
Mugo additionally stresses the necessity for coverage adjustments that facilitate the approval of multipurpose prevention applied sciences (MPTs) that may concurrently stop HIV, being pregnant, and sexually transmitted infections (STIs).

“The one multi-purpose know-how product we’ve got is the condom. The condom truly does all three, protects pregnancies, HIV and STIs. However the challenges is, it is a man who makes use of a condom, except it is a feminine condom. So perhaps we have to do extra work to reintroduce the feminine condom,” says Mugo.
Shaping the Way forward for HIV Prevention
As analysis continues, the way forward for HIV prevention in Africa seems vibrant. Growing long-acting, easy-to-use prevention instruments might dramatically scale back the incidence of latest infections, significantly amongst younger folks, who’re most in danger.
“If we will get these merchandise into the arms of younger folks, we will defend a complete technology, says Mugo.
The potential for decreasing group viral masses can be a game-changer.
“The less folks with HIV in a group, the decrease the danger of latest infections,” Mugo says. “By offering long-acting prevention instruments to as many individuals as potential, we will create a ripple impact that reduces the general variety of infections and strikes us nearer to eliminating HIV.”
With continued analysis, collaboration, and group engagement, the dream of a world with fewer HIV infections and finally, no HIV in any respect—might quickly change into a actuality.
