The AIDS 2026 conference is fast approaching. To help advocates stay informed and engaged, AVAC has curated a collection of its Advocates’ Guides covering the science, policy, implementation and advocacy conversations shaping the future of the HIV/AIDS response. Developed with partners across the field, these guides help translate complex science and policy to help inform advocacy before, during and after the conference.

For those presenting at AIDS 2026, please check out AVAC’s slide deck containing the latest infographics on the research & development pipelines, the delivery of new prevention options and the impact of US funding cuts on foreign assistance and on research and science. We will be continuously updating it, so be sure to check back for updates as the conference approaches.

The introduction of injectable lenacapavir for HIV PrEP (LEN) is underway–in some places at least. To ensure communities remain at the center of LEN rollout, this new Advocates’ Checklist for Lenacapavir for PrEP Introduction is an immediate, actionable blueprint. And read more in this blog by the co-chairs of the Civil Society Caucus of the Coalition to Accelerate Access to Long-Acting PrEP and AVAC staff.

Planning For MK-8527

Expanding prevention choice means investing in a diverse pipeline of HIV prevention options. MK-8527 is an investigational antiretroviral (ARV) once-monthly oral PrEP pill that is currently in Phase III clinical trials. If proven safe and effective, it could offer another important PrEP option. This resource provides advocates with an overview of the MK-8527, the science behind it and the latest on its clinical development.  

Podcast: The Future of PrEP

AVAC’s Executive Director Mitchell Warren joined ITPC’s Make Medicines Affordable podcast to discuss the future of PrEP. While Lenacapavir is a transformative option for HIV prevention, Warren shares what it will take to ensure it reaches the people who need it most.

UN member states adopted a new Political Declaration on HIV/AIDS reaffirming global commitments to end AIDS by 2030, but for the first time since 2001, the declaration was not adopted by consensus – and with the US notably voting against it. At the same time, last week’s news that the US Department of State is assuming greater control over PEPFAR is followed this week by the phase-out of US PEPFAR support for South Africa and new analyses showing PEPFAR-supported HIV treatment declined in 2025, following the US Administration’s foreign aid freeze. Also, for organizations in the US, please consider signing Partners in Health’s Letter to Protect CDC PEPFAR Programs.

UN HIV Declaration Adopted Amid Deep Political Divisions

The UN General Assembly adopted a new Political Declaration on HIV/AIDS this week reaffirming global commitments to end AIDS as a public health threat by 2030. However, for the first time since political declarations on HIV began in 2001, the declaration was not adopted by consensus. And importantly, the US delegation voted against the declaration. Deputy US Representative to the UN, Tammy Bruce, said in a comment rejecting the declaration that it strayed too far from the targets for ending AIDS “by including divisive topics”. The declaration acknowledges that progress toward the 2030 goal is off track, highlighting widening funding gaps, disruptions to HIV services, and persistent barriers faced by populations at high risk of HIV. Advocates and civil society played an important role in ensuring the declaration included commitments to evidence-based, rights-based HIV responses and renewed calls for sustained investment in prevention, treatment and community-led services.

IMPLICATIONS: The divided vote underscores how geopolitical tensions and domestic politics in the US are shaping global health policy at a moment when the HIV response faces its greatest financing crisis. While the declaration provides an important political framework for countries and advocates, it carries no binding obligations and offers few concrete answers to address the growing funding shortfall as nationalism rises and development assistance falls. The US government’s opposition marks an insular, ideologically driven retreat from longstanding consensus for rights-based HIV programming, particularly for key populations who continue to bear a disproportionate burden of HIV. This is consistent with the harmful policies and positions the US Administration has taken against communities vulnerable to HIV including the Promoting Human Flourishing in Foreign Assistance (PHFFA) and the invisibility of vulnerable populations in the most recent PEPFAR data.

In response, global civil society groups led by Health GAP have elevated the People’s Declaration on HIV/AIDS as a counter to the resulting Political Declaration. Over 400 organizations signed onto the People’s Declaration, illustrating a major show of power and call for action by governments to reaffirm commitments, rights, and investments to end HIV for everyone, everywhere.

US Ending PEPFAR in South Africa

The US Administration abruptly announced its intention to end PEPFAR support in South Africa, with funding expected to terminate by early 2027. The decision is part of the Administration’s broader retrenchment from foreign assistance and is related to political disagreements with the South African government. South Africa receives more than $400 million annually through PEPFAR, which supports health workers, prevention programs and service delivery. This decision marks one of the most consequential changes to PEPFAR since its creation in 2003, with significant implications in envisioning an end to the HIV epidemic – in South Africa and globally. This news follows the Administration’s Executive Order in February 2025, which made baseless claims about South Africa, and the March 2025 decision to “hold all research awards” for South Africa after designating it a “country of concern”. At the time, AVAC told Bhekisisa, “It is very clear that the President is using budgets and terminations of previously agreed to programmes to redefine agendas… that defy science and are clearly political and ideological.”

IMPLICATIONS: The PEPFAR withdrawal from South Africa reinforces the shift away from evidence to ideology, moving from long-term global health partnerships toward a more transactional foreign policy model. These short-sighted decisions come despite the historical South Africa-USA partnership that has catalyzed scientific research and program impact for HIV prevention and treatment, where the country plays a vital role in clinical research, development of cutting-edge prevention technologies, and implementing models for treatment, care and prevention. Although South Africa finances its own antiretroviral medicines, PEPFAR supports important aspects of the health workforce, community-based prevention and services for key populations. A rapid withdrawal will disrupt testing, prevention and services, placing additional strain on the country battling the largest HIV epidemic. Furthermore, the end to PEPFAR funding along with the severance of National Institutes of Health (NIH) research partnerships, cuts off a country that is central to ending the global epidemic and one that continues to inform the science of HIV and tuberculosis treatment and prevention.

New Analysis Shows Decline in PEPFAR-Supported HIV Treatment

A new analysis published in Nature Health finds that PEPFAR-supported HIV treatment declined in 2025 following the US Administration’s foreign aid freeze, with approximately 2 million fewer people reported as receiving PEPFAR-supported antiretroviral therapy than in 2024 (a 10% decrease). Of the 26 countries examined, treatment support fell across all, though some of the decline reflects changes in how PEPFAR classifies and reports treatment support rather than patients losing access to care. South Africa was called out in the analyses, accounting for most of the treatment declines—individuals previously counted as receiving direct PEPFAR support were reclassified as benefiting from broader health system investments, resulting in a net treatment decline of about 95,000 people (1.8%). The authors conclude a “decline of ∼1.73 million individuals on direct PEPFAR-supported treatment and an increase of ∼1.64 million individuals on treatment benefitting solely from the programme’s broader support to health systems, yielding a net treatment loss of 94,881 (−1.8%)”.

IMPLICATIONS: As the authors conclude, “while the analysis cannot determine whether and to what extent declines will translate into reduced individual- or population-level treatment outcomes, a reduction in PEPFAR-supported treatment of this scale within a single fiscal year raises concerns.” The data underscore the significant disruptions caused by funding uncertainty and restructuring across the program.

Add Your Voice to Stop OMB’s Attack on American Science

Proposed new regulations by the White House Office of Management and Budget (OMB) would use budgetary and regulatory tools to bypass longstanding scientific peer-review and congressional processes, including withholding appropriated funds, restructuring federal agencies, and proposing rules that would give political appointees greater influence over research funding decisions. Public comments are due by July 13th – please consider taking action and visit Stand Up for Science’s STOP OMB portal now.

This week, the US Administration continues to move to consolidate control over science, restructure the systems that underpin PEPFAR and global health security, and redefine US global health engagement through regulatory influence rather than long-term public health partnerships.

Restructuring PEPFAR and Weakening the US CDC

The US Administration is moving forward with its plan to significantly reduce the US Centers for Disease Control and Prevention’s (CDC) vital role in PEPFAR and global health programs, shifting much of the authority and funding to the US Department of State, which many argue, does not have the expertise or capacity to manage the programs. In contrast to CDC’s historical role in implementing PEPFAR in-country programs, the plan would require countries to “purchase” CDC technical assistance services (ranging from disease surveillance to laboratory support) through new bilateral agreements in a “fee-for-service” public health model. The future of in-country CDC offices and technical staff is uncertain under this new plan.

The Administration already significantly weakened PEPFAR’s infrastructure by shutting down USAID last year and delaying HIV funding in an interagency transfer to CDC. This new proposal could further undermine the CDC from much of the work that helps deliver HIV services and supports disease detection around the world. As eight former CDC directors – appointed by both Republican and Democratic presidents – warned previously, the proposed restructuring could disrupt not only HIV services but also the laboratory networks, surveillance systems, trained workforce and trusted relationships with ministries of health that support outbreak detection and response worldwide.

IMPLICATIONS: “This will completely destabilize HIV work abroad,” former CDC official Michele Montandon told the New York Times. “We’ve seen service disruptions, deaths and babies born with HIV after shuttering USAID, and we can expect more to come if CDC is also shut out of this work.” The rapid restructuring of PEPFAR could decimate HIV programs, complicate the transition to country ownership, and fracture global disease surveillance and outbreak-response systems built through decades of US investment. While there is broad stakeholder agreement about the importance of increasing country ownership and transitioning away from donor dependence, the accelerated pace and structure of the proposed changes makes technical expertise and relationships precarious before sustainable alternatives are in place. These changes come at a time of a rapidly unfolding Ebola epidemic in Central Africa, complicating current crises and creating doubt in response capacity for future epidemics.

Political Control Over Science Moves Ahead

The proposed new regulations that would significantly expand political interference in federal funding decisions across all US government grants by the White House’s Office of Management and Budget (OMB) remains at the center of current controversy. In a recent New England Journal of Medicine editorial, editors warned that this Administration is increasingly using budgetary and regulatory tools to bypass longstanding scientific peer-review and congressional processes, including withholding appropriated funds, restructuring federal agencies, and proposing rules that would give political appointees greater influence over research funding decisions. At the same time, Hal Duncan, the nominee to serve as the Deputy Director of the OMB, defended the “pocket rescission” strategy during his confirmation hearings this week in front of Senate leaders. This strategy would allow the Administration to use additional spending cuts through “pocket rescissions,” which would allow funds to expire before Congress has an opportunity to act.

IMPLICATIONS: The moves by OMB signal increasing efforts to shift decision-making authority away from Congress and scientific peer review and toward the Executive Branch, giving the President more control over how federal money is spent and what research and programs get funded in alignment with ideology. For the last 18 months, the question of who gets to decide what scientific research and public health programming are funded and whether Congress’s decisions are carried out as intended continues to be raised, and the answer increasingly appears to be the White House rather than Congress or the broader scientific and public health community.

Scientists Issue Bethesda Declaration: One Year Later

Nearly 40 former and current staff at the National Institutes of Health (NIH) authored a new report, The Bethesda Declaration One Year Later, Continuing Harms to the NIH Mission, which outlines nine deepening concerns at the NIH over the last year along with proposed solutions. This report comes one year after hundreds of NIH employees accused the Administration of politicizing biomedical research through the original Bethesda Declaration. The new report notes that the Administration is slowing medical research, disrupting international collaborations, weakening ethical safeguards, driving away experienced staff and undermining public trust in science. Approximately 24% fewer NIH research projects were funded in 2025 than in 2024 and more than 5,500 peer-reviewed grants were terminated. The report also warns that the White House’s proposed Office of Management and Budget (OMB) rule, which would subject federal grants to greater political review and require alignment with presidential priorities, would institutionalize many of the changes researchers have opposed in the last year.

IMPLICATIONS: The updated Bethesda Declaration shows growing concern from the scientific community about the politicization of science. The NIH has served as the foundation of HIV research, from supporting basic science, vaccine development, implementation of new prevention technologies and global research partnerships. As political oversight expands and international collaboration is deconstructed, the US risks undermining the scientific infrastructure that has fueled decades of innovation and partnership.

US FDA and African Medicines Agency Enter Into New Partnership

The US Food and Drug Administration (FDA) and the African Medicines Agency (AMA) have signed a new Memorandum of Understanding (MoU) to create a shared framework for information sharing and regulatory cooperation. The agreement could allow African regulators to draw on FDA assessments and regulatory decisions when evaluating medical products, while also facilitating greater cooperation on inspections, scientific reviews and regulatory capacity building.

IMPLICATIONS: This agreement between two stringent regulatory authorities (SRAs) is another example of the Administration’s evolving approach to global health and in-line with the US government’s recent “America First” global health strategy. This partnership could be interpreted as a regulatory harmonization effort that would allow for the rapid influx of American-made health technologies for emerging markets in Africa. The expansion and procurement of US-made health commodities is a central feature to the US government’s new transactional approach to global health. However, this comes in stark contrast as the US cuts funding for global health programs, reduces the CDC’s international role and restructures PEPFAR, it is replacing long-term public health partnerships with narrower bilateral agreements focused on regulation and innovation. The disconnect between developing new health technologies and supporting the health systems needed to deliver them complicates the vision for greater regulatory cooperation between SRAs that is required for scale-up and access to the latest treatment and prevention modalities.
