WHO recommends injectable lenacapavir for HIV prevention

The World Health Organization (WHO) released today new guidelines recommending the use of injectable lenacapavir (LEN) twice a year as an additional pre-exposure prophylaxis (PrEP) option for HIV prevention, in a landmark policy action that could help reshape the global HIV response. The guidelines are being issued at the 13th International AIDS Society Conference (IAS 2025) on HIV Science, in Kigali, Rwanda.

LEN, the first twice-yearly injectable PrEP product, offers a highly effective, long-acting alternative to daily oral pills and other shorter-acting options. With just two doses per year, LEN is a transformative step forward in protecting people at risk of HIV – particularly those who face challenges with daily adherence, stigma, or access to health care.

The new guidelines come at a critical moment as HIV prevention efforts stagnate with 1.3 million new HIV infections occurring in 2024 – with disproportionate impact among key and priority populations, including sex workers, men who have sex with men, transgender people, people who inject drugs, people in prisons, and children and adolescents. WHO’s recommendation on LEN signals a decisive move to expand and diversify HIV prevention, giving people more options to take control over their health with choices that fit their lives.
