The Cruel Irony of Prevention

FDA approves LEN, while the administration destroys USAID

It’s been 22 weeks since the US president issued the executive orders that began the chaotic dismantling of USAID. See recent, remarkable, and much-needed New York Times coverage on the destruction of USAID. And check out this new episode of the This American Life podcast on the aftermath of shutting down USAID.   

We at AVAC took a public stand against this attack on global health and development in our court case, AVAC v. United States Department of State, filed by Public Citizen on February 10. We took this step because we understood the devastation that would come from such drastic and sudden divestment in the HIV response and global health. We also believe it was illegal and unethical.  

In March, US District Court Judge Amir Ali ruled the foreign aid freeze was, indeed, unlawful, and that the administration had “usurped” the authority of Congress. Since that time, some 400 grants have been restored and the government is slowly complying with the Judge’s order to pay all invoices for work conducted through February 13. It’s a mere fraction of USAID’s former self, but each of these restored programs and payments represent an attempt to make America and the world stronger, safer and more prosperous. Just as important, our court case, along with a related one brought by the Global Health Council and colleagues, has forced into the public record the administration’s cynical maneuvers to dismantle global health; information that empowers advocates to fight and, we hope, finally spurs Congress to do its job.

“We cannot cede ground gained against HIV and other global health threats out of fear or paralysis in the face of these reckless actions. It is imperative to hold this administration responsible. And it’s imperative to invest in global health and sustain the gains in HIV. Global health advocates know this better than anyone, and we are fighting back,” said AVAC Executive Director, Mitchell Warren.

Watch AVAC’s Executive Director, Mitchell Warren’s video explaining how this court case is one of many critical steps to safeguard global health and the HIV response.

Nowhere is that fight to safeguard and advance HIV prevention more important than work to rollout injectable lenacapavir (LEN) for PrEP, just approved by the US Food and Drug Administration. LEN approval signals what could be a turning point in the epidemic – but only if the field invests in bold, strategic action. 

“The science is remarkable, and the FDA approval is in. But it’s what happens next that makes the science count. It’s whether or not the technology is made available and becomes truly accessible that will bring impact. Will the world get it right this time? Because for 15 years we’ve squandered the potential of PrEP. That hope depends on fierce and effective advocacy,” said Warren.

HIV prevention advocates around the world are demanding and preparing for injectable LEN to reach the communities that need it most with speed, scale and equity. Watch this video for more on status of LEN rollout and advocacy priorities.

“Scientific progress has been made over the years, and we celebrate them, but without truly having a prevention story to tell…yet. Now it’s time for that story to be told,” said APHA Executive Director Yvette Raphael.

Read this report from Friends of the Global Fight Against AIDS, Tuberculosis and Malaria, Principles of a responsible transition of American leadership to end AIDS: Strategic transition or pandemic resurgence?, on how PEPFAR and US leadership can play an instrumental role in reaching epidemic control.

“There’s much work advocates are doing, and much work ahead. Some donors have come forward, but it’s only a start. We also need to advocate with regulatory authorities at the country level, not to mention pushing for an affordable price, and a big enough supply from Gilead now to support demand creation at scale in order to build a sustainable market, which in turn will support generics and further reductions in price. Advocates are now and will continue to be fighting at the country level and the global level to move all this forward,” said HEPS Uganda Executive Director Kenneth Mwehonge and co-chair of the Civil Society Caucus of the Coalition to Accelerate Access to Long-Acting PrEP.

Check out the Caucus statement on priorities for LEN rollout, and these resources to support our collective advocacy:

Recent news headlines, including the just published New Yorker magazine article by Science reporter Jon Cohen, capture the power of this moment to reshape the HIV response and finally control the epidemic. As advocates, we know the stakes very well.

“What all of us working together have tried to do for years and years and years, is to overcome the barriers from stigma to disinformation, that we’ve seen with oral PrEP, and with treatment 20 years ago. It will take Gilead, working with all of us advocates, to collectively ensure that this drug is accessible to all, so that the success depends not on the politics but on the product. We have to hold everyone, including ourselves, to account for keeping on task and for making sure that we do not squander this opportunity. So, let’s do this together and lay the groundwork for all future innovations to go faster, with speed, with scale and with equity for all,” Warren said.

The field is at a major inflection point, punctuated by both political challenges and scientific opportunity – and we can’t let the former overtake the latter.

FDA Approves Injectable Lenacapavir for PrEP

A Historic Milestone Must Now Be Matched by Urgent Action

Contact: [email protected]

New York, NY, June 18, 2025 — AVAC welcomes the U.S. Food and Drug Administration (FDA) approval of injectable lenacapavir (LEN) for the prevention of HIV as pre-exposure prophylaxis (PrEP). LEN, developed by Gilead Sciences, is a twice-yearly injectable PrEP option that showed nearly complete protection against HIV in the landmark PURPOSE 1 and 2 trials. Science Magazine named LEN the “Breakthrough of the Year” in 2024, a recognition that reflects its enormous potential. But that promise will only be realized if it is rolled out with speed, scale, and equity.

“The approval of LEN is a much-needed boost for HIV prevention, given the strength of the science and the simultaneous disruption in HIV programs globally,” said Mitchell Warren, executive director of AVAC. “But US FDA approval is just one in a series of steps needed to ensure that injectable LEN can help reduce the 1.3 million new HIV infections that occur each year. Scientific progress only matters if innovation actually reaches people. LEN for PrEP is poised to re-shape the HIV response, but only if today’s approval is accompanied by bold, strategic, effective and equitable rollout that reaches the populations that need access. Otherwise, the world risks squandering this PrEP opportunity, as it has with other PrEP options too often over the past 12 years.”

In December, PEPFAR and the Global Fund announced a coordinated ambition to reach two million people within three years of product launch. This commitment signals an unprecedented opportunity to make PrEP access a reality. But translating this ambition into impact, especially now amid the current political environment, is not without considerable challenges.

“Political will, programmatic implementation, and sustainable funding are needed to truly accelerate equitable and impactful introduction of LEN worldwide,” said Wawira Nyagah, AVAC’s director of product introduction & access. “We have over a decade of hard-won lessons on what it takes to rollout PrEP effectively, and the field cannot afford the delays we have seen with the past launches of daily oral PrEP, the monthly dapivirine vaginal ring (DVR), and every-two-month injectable cabotegravir (CAB). Lives depend on speed, scale and equity.”

The World Health Organization (WHO) is expected to release updated PrEP guidelines for LEN in July, and regulatory agencies in Brazil, Europe and South Africa are simultaneously reviewing the product. But the current political context, including a shuttered USAID and further disruptions across global health, demands an urgent and courageous response. In January, the US Administration issued a stop-work on all USAID-funded grants, nearly paralyzing HIV treatment and prevention by PEPFAR, the primary funder of programs in HIV-burdened countries (and administered by USAID). In February, PrEP was broadly excluded from a waiver that allowed HIV treatment to continue and allowed PrEP only for pregnant and breastfeeding women. These policies could not only undercut LEN’s promise but roll back years of progress in HIV prevention.

It will take new, re-vitalized and committed partnerships to work together to sustain past progress and advance HIV prevention to deliver on the UN targets for epidemic control. AVAC’s The Gears of Lenacapavir for PrEP Rollout outlines the steps needed from national governments, funders, researchers, drug-makers including generic manufacturers, and civil society to ensure LEN reaches those who need it most. In the near term, these stakeholders each have vital work to do to complement the initial announcement from the Global Fund and The Children’s Investment Fund Foundation (CIFF) in their pledged collaboration to significantly expand access to LEN for PrEP.

“No one donor, national government or manufacturer can realize this ambition alone,” said Warren. “All stakeholders—including Gilead, PEPFAR, and the Gates Foundation—must act decisively to seize this opportunity, ensuring that all populations—regardless of geography, income, or identity—benefit from this innovative prevention option.”

Meeting this moment requires funders, Ministries of Health, implementers and civil society partners to collaboratively design a comprehensive introduction strategy that breaks the sequential nature of traditional approaches to scaling up interventions. Instead, to speed up introduction, stakeholders must move toward a parallel approach where research, implementation science, and programs at scale are designed, funded and implemented simultaneously. This introduction strategy should entail:  

  • Other funders and national governments to join the Global Fund and CIFF and commit to procure at least enough LEN from Gilead for two million person years of protection beginning this year through 2027. 
  • Gilead to set a cost-effective price that compares to generic daily oral TDF/FTC. Achieving this will require a low launch price from Gilead, significant volume procurement from donors, and the entry of multiple generic manufacturers into a competitive, multi-million-user market. While this low price is not expected at launch, stakeholders must act now to reach this price point as quickly as possible by building volume with supplies from Gilead at no more than $100 per person per year and to support multiple generic manufacturers to enable production at larger scale and lower prices as quickly as possible.
  • A mobilized civil society in high-burden countries pushing national governments to expedite regulatory approvals, integrate LEN into HIV and national health programs with domestic resources, and develop national guidelines without delay.
  • Civil society also demanding transparent pricing and a clear, accelerated pathway to sustainable PrEP programs—so that by the time generic LEN becomes available around 2028, the market is primed for rapid scale-up, with multiple producers driving down prices through competition.
  • Gilead working with their generic license holders to accelerate production and expand generic availability in middle-income countries.
  • The US Administration, via the State Department, releasing all appropriated funds, negotiate best prices at scale and provide LEN to all who need it. These actions are essential to achieve a strategic transition and sustainability against the global HIV epidemic.

“This is the moment to build on the momentum of science, which has brought the field to this day, when LEN for PrEP is speeding through regulatory review faster than any prevention product to date,” said Nyagah. “Translating this success into real impact on the epidemic, led by communities around the world, must be a top priority among all stakeholders.”

Global Health Watch: WHA78, Misinformation at Congressional Hearings, Global Fund Cuts & More

Issue 17

The US Secretary of State and the Secretary of Health and Human Services appeared before Congress this week defending foreign aid cuts and the dismantling of USAID. Advocates are responding, including the Treatment Action Group (TAG) which issued a stark warning: US agencies are engaging in “unethical, dishonorable, and potentially law-breaking machinations” under new leadership, particularly at the NIH. Meanwhile, the US was absent from the World Health Assembly, where the WHO Pandemic Agreement was ratified and where a high-level dialogue on long-acting HIV prevention took place. All this plus looming Global Fund shortfalls, and new COVID-19 vaccine policy changes in this week’s issue. 

Misinformation and Controversy at Congressional Hearings 

The US Secretary of State Marco Rubio appeared in front of the US Congress this week defending radical cuts to foreign aid and a proposed State Department reorganization that deprioritizes global health programs. In front of the Senate Foreign Relations Committee (of which he was once a member), Rubio was corrected when he wrongly claimed that only 12% of US funding goes to direct services. In fact, 12% is the proportion of funds going directly to local NGOs, with 85% of total funding going towards direct services. He also claimed – without evidence – that 85% of PEPFAR beneficiaries were still receiving services and denied any deaths linked to the US cuts. The Secretary repeated these claims before the House Foreign Affairs Committee and Appropriations State and Related Programs subcommittee and ignorantly characterized voluntary male medical circumcision (VMMC) as wasteful spending. VMMC is proven to reduce transmission of HIV. Congressional members challenged Secretary Rubio on the legality of the foreign aid freeze and dismantling of USAID and highlighted reported deaths resulting from the cuts. Meanwhile, some Republican Senators, including Senate State, Foreign Operations, and Related Programs (SFOPs) Chair Lindsay Graham, expressed support for foreign assistance amidst calls for transparency and metrics to transition countries off US funding. 

Department of Health and Human Services (HHS) Secretary, Robert F. Kennedy Jr. appeared before the Senate this week to defend cuts to public health programs and biomedical research. Similar to his appearance last week before the Senate Health, Education, Labor and Pensions (HELP) Committee, Kennedy’s remarks were controversial and contradicting.  

IMPLICATIONS: These hearings underscore the challenges facing US global health policy and programming amid shifting political priorities and leadership. Advocacy to counter mis- and dis-information, and a vision for this new era of global health financing, are more important than ever.

World Health Assembly Updates 

The United States was notably missing from the World Health Assembly (WHA) this week, with no official delegation attending. This is a major change from previous years where delegations held leadership and diplomacy roles. In contrast, China sent more than 180 delegates and pledged an additional $500 million over the next five years to help stabilize the agency following the withdrawal of the United States, reinforcing its growing influence in global health governance. 

Meanwhile, the WHA formally voted to adopt the WHO Pandemic Agreement, a legally binding accord that lays the foundation for future pandemic prevention and response, including real-time sharing of vaccines, treatments, and diagnostics. For three years, member states negotiated critical issues, with pressure from civil society to embrace key provisions on equity and intellectual property. Some of those provisions have been addressed, but negotiations on an annex detailing the new Pathogen Access and Benefit Sharing (PABS) mechanism will continue with the aim of concluding at next year’s WHA. PABS refers to a proposed system where countries share genomic information about novel pathogens and share tools developed to combat those pathogens, regardless of which country discovered the pathogen or developed effective tools—it has been one of the most contested areas of negotiation. Though the treaty is less ambitious than earlier drafts, nations at the WHA have largely welcomed the agreement as a major achievement.  

Many events and discussions were held on the sidelines of the WHA, including Wednesday’s high-level dialogue organized by the Global HIV Prevention Coalition (GPC). The event, A New Era of HIV Prevention: Accelerating Access to Long-Acting Prevention Options, was co-hosted by UNAIDS, in collaboration with the United Nations Population Fund (UNFPA), United Nations Development Fund, (UNDP), WHO, the Federal Republic of Brazil and Kingdom of the Netherlands. AVAC’s Mitchell Warren, who also co-chairs the GPC, opened the session with urgency and optimism, calling it “one of our greatest opportunities in 44 years of HIV prevention,” even as global solidarity is waning. Dr. Lilian Benjamin Mwakyosi, a past AVAC Fellow and director of DARE in Tanzania issued a powerful reminder that “choice for HIV prevention is not a luxury. It’s a right,” stressing that adolescent girls and young women need accessible, discreet prevention options like long-acting PrEP. The dialogue underscored the need for political will, financing, and community-centered action to turn scientific breakthroughs like lenacapavir for PrEP into sustained prevention at scale.

Global Fund Financial Challenges 

More than 260 civil society advocates joined a conversation organized by the Coalition to build Momentum, Power, Activism, Strategy & Solidarity (COMPASS), Eastern Africa National Networks of AIDS and Health Service Organizations (EANNASO), CHANGE, and others to explore the financial constraints facing the Global Fund following its Board meeting earlier this month. Advocates learned unmet pledges and declining global health aid will mean that the current Global Fund Grant Cycle 7 will reduce allocations to countries to align with available resources, moving from pledge-based to cash-based allocations. Countries will receive reduced funding envelopes in mid-June 2025, which will trigger a two-week reprioritization process to focus on life-saving services like treatment continuity and community-led monitoring while deferring lower-priority items. 

IMPLICATIONS: These changes could jeopardize essential programs, especially those supporting key populations. And they also raise significant questions about the recently launched Global Fund replenishment for the next grant cycle. Civil society must prepare now to advocate for transparent processes, protect vital community interventions and support the Global Fund’s ambition to introduce injectable lenacapavir with speed, scale and equity. 

New US COVID-19 Vaccine Policy 

The US Food and Drug Administration (FDA) outlined in a new blueprint for COVID-19 vaccines, one that shifts from a recommended annual COVID vaccine for everyone 6 months and older, to adults over 65 and individuals with high-risk conditions, such as compromised immune systems. This shift requires vaccine manufacturers to conduct extensive clinical trials before approving vaccines for healthy individuals aged 6 months to 64 years, potentially delaying access for this group. Rather than proposing the new guidelines through the typical regulatory processes, including opportunities for public comment, this framework was devised and published by the head of the FDA along with the new head of FDA’s Center for Biologics Evaluation and Research (CBER).  

IMPLICATIONS: This unorthodox process could complicate future vaccine approvals, as well as leave interpretation and coverage decisions up to insurers, which would create major access barriers for many.

100 Days In: How HIV Advocates are Meeting the Moment

In its first 100 days, the Trump administration proposed deep cuts to public health and HIV funding, attacked evidence-based healthcare, defunded scientific research, rolled back protections for LGBTQ+ people, and emphasized punitive criminal legal approaches. These moves pose serious threats to the future of HIV-related services, care, prevention, and the broader struggle for health equity and racial justice in our multiracial democracy.

Join CHLP for this moderated panel discussion focused on what the first 100 days of the Trump administration have meant for our communities, particularly people living with HIV, Black and brown people, LGBTQ+ people, and those impacted by criminalization, and how we are collectively shifting strategy to meet the current political moment.

HIV Prevention R&D at Risk

Tracking the Impact of US Funding Cuts

The US presidential administration is actively working to dismantle HIV research and demolish the architecture of global health. The entire HIV response — from basic research and clinical development to policy, programs, and global access to life-saving treatment and prevention — is now under attack, and the world runs the risk of reversing the strides made to end HIV.

AVAC has put together this report, highlighting the impact of US cuts on the pipeline of HIV prevention research and development. AVAC will continue to track these cuts and their impact, to amplify the damage they will cause, and to fight for their reversal.
