Cambodia has officially exceeded the 95-95-95 HIV targets. AIDS deaths are down nearly 80%. But sustaining these gains through Cambodia's own health systems and financing is the next frontier. A level up, not a finish line. 🇰🇭 @UNAIDS @MOHCambodia #EndAIDS

Oral PrEP initiations fell 42% in 2025. At the same time, injectable #lenacapavir launched at $40/person/year—negotiated by CHAI, @Unitaid, @WitsRHI, and @drreddys. The tool exists. The delivery system is eroding. ow.ly/za6l50Z8apV

26K fewer children on HIV treatment by end of 2025. Behind every number: cut community health workers, test kit shortages, collapses pediatric services. This is what funding cuts look like for kids. Our new HIV Market Impact Memo, w/support from @Unitaid: ow.ly/txZc50Z8amz

New from CHAI and @Unitaid: a year into the HIV funding crisis, data shows little recovery. One exception: adults on treatment held stable. Full memo: ow.ly/cF0W50Z8a8k

Today, the first doses of lenacapavir were rolled out in South Africa, marking an important step in expanding HIV prevention options. At Unitaid, we're working with partners to support implementation and accelerate access through affordable generics and regional manufacturing.

Six countries pledged US$185M for women's & newborns' health supplies at #WHA79. Not a coincidence: that's the gap aid cuts are projected to leave in contraceptive funding in 2026 alone. Ethiopia, Ghana, Honduras, Nigeria, Senegal & Zambia are stepping up. ow.ly/eofV50Z3c9u

NEW at #WHA79: Livelihood Impact Fund launched the Global Vision Impact Award, catalytic funding for 15 governments to build national reading glasses programs. 800 million people lack access to glass that cost <US$1 to produce. Governments can apply now. ow.ly/UoeX50Z2iCZ

African governments are building health systems that thrive on their own resources. Today @ONEinAmerica & CHAI announced a partnership to support them in Nigeria, Senegal, & Sierra Leone. Because no mother should have to bankrupt her family to access care. ow.ly/8Sbr50YVaWH

In cities, parents couldn't afford the time off work. In nomadic communities, families were constantly on the move. In farming areas, cultural beliefs kept people away. #WorldImmunizationWeek

Ethiopia’s MoH & CHAI worked with communities to design solutions that fit each reality — because one approach was never going to be enough. globalhealthhub.de/en/news/d… #WorldImmunizationWeek

In Indonesia, 220,000 children were flagged as zero-dose. Many had already been vaccinated — just not recorded. Fixing the data was the first step to reaching those truly missed. ow.ly/RWcq50YQJMp #WorldImmunizationWeek
