In a significant advancement for global HIV prevention, the United States has authorized the use of the first-ever injection administered twice a year to prevent HIV infection.
This development represents a major milestone in efforts to reduce new infections, particularly among individuals most at risk.
The injectable medication, lenacapavir, created by Gilead Sciences, has demonstrated exceptional efficacy in clinical studies. Health experts suggest it could revolutionize HIV prevention, especially for those who find it challenging to take daily oral preventive medications.
“This could truly be the turning point in stopping HIV transmission,” said Greg Millett, Director of Public Policy at amfAR, The Foundation for AIDS Research.
Although an effective vaccine for HIV remains elusive, lenacapavir is being hailed by many in the medical field as the most promising alternative currently available. In large-scale trials, the long-acting injection was shown to dramatically reduce new HIV infections in individuals at high risk, outperforming existing daily PrEP (Pre-Exposure Prophylaxis) options like Truvada and Descovy.
Unlike traditional PrEP, which relies on strict daily adherence to remain effective, lenacapavir only needs to be administered once every six months. This could significantly improve adherence and protection among users who struggle with daily medication routines.

While U.S. regulatory approval marks a historic step, the broader impact of lenacapavir will depend heavily on how access is managed both within the country and internationally. Cost, availability, and healthcare infrastructure will be key in determining how widely the drug can be distributed—especially in lower-income nations where HIV prevalence remains high.
Public health advocates are urging Gilead and global health agencies to ensure the medication is accessible to all who need it. Without equitable distribution, experts warn that the full potential of this breakthrough may be realized only in wealthier nations with robust healthcare systems.
Though condoms and daily PrEP will still play a vital role in preventing HIV, lenacapavir offers a potentially more convenient and discreet alternative for millions. Health officials are optimistic that the twice-yearly shot could be a game-changer, especially in communities affected by stigma, poverty, or limited access to regular healthcare.
As the rollout begins, global attention is now focused on how quickly and equitably this innovation can reach those in need.
The promise of lenacapavir is not just in its science—but in its potential to transform lives around the world.
