Global Health Watch: Fauci in Contempt + New NIAID Director, Senate Blocks OMB’s Grant Proposal, New CDC Director, AIDS 2026 Highlights

Issue 80

This week, the US Senate Committee on Homeland Security & Governmental Affairs voted along party lines to hold Anthony Fauci in contempt of Congress for his refusal to answer questions during last week’s hearing on the COVID-19 response testimony – while it was rumored that Steven Quay, a lab-leak proponent, is in line for Fauci’s old job. At the same time, the US Senate Appropriations Committee did step up to stop the White House OMB’s politicization of federal research grants. There’s also – finally – a new leader of the US Centers for Disease Control and Prevention (CDC). And the HIV/AIDS community is unpacking major themes emerging from the AIDS 2026 conference.

Anthony Fauci and the Future of NIAID

The US Senate Committee on Homeland Security & Governmental Affairs voted Thursday to hold former NIAID Director Anthony Fauci in contempt of Congress, raising a years-long political campaign against him just a week after he was grilled by Republican Senators for hours over the COVID-19 pandemic and its origins. Much of the scientific and public health community rallied around him after his appearance: “Dr. Fauci is a public health pioneer, who has saved more lives than anyone sitting in the Senate today. He has dedicated his life to public service. Because of Tony Fauci, science has moved faster, lives have been saved and communities are more engaged in every phase of infectious disease research,” wrote AVAC’s Executive Director in a statement. “[Fauci’s] career was built on evidence, intellectual rigor and an unwavering commitment to improving people’s lives,” wrote American Society for Microbiology CEO Stefano Bertuzzi in a letter to the committee, calling Fauci’s scientific record “the gold standard.”

Following the hearing, Health and Human Services Secretary (HHS), Robert F. Kennedy Jr. (RFK Jr.) appeared in media interviews targeting Fauci and pushing misinformation on vaccines and medical information, all while preparing to appoint Steven Quay, a pharmaceutical executive and prominent advocate of the COVID lab-leak theory (and longtime Fauci critic) to lead NIAID, the agency Fauci and then Jeanne Marrazzo directed for nearly four decades and which oversees $6.5 billion in annual research funding. Quay was not even among the finalists interviewed for the role, but Kennedy selected him nonetheless, according to Politico. Quay—a physician and pathologist—could become the first NIAID director drawn from the pharmaceutical industry rather than academia or the NIH, despite lacking formal training in infectious diseases.

IMPLICATIONS: Quay’s expected appointment would mark a major shift in the leadership and direction of NIAID, which is arguably the world’s most influential biomedical research agency. This, along with the Senate Committee’s decision to hold Fauci in contempt of Congress signals that alignment with the Administration’s ideology is more important than scientific expertise in setting US research priorities and public health policy. Together, the message is clear: if you dare to challenge political ideology, it has consequences. This will likely have a chilling effect on researchers and scientists reluctant serve in government and speak out during health crises.

US Senate Blocks White House OMB’s Grant Proposal Temporarily

This week US Senators on both sides of the political aisle moved to temporarily block the White House Office of Management and Budget’s (OMB) proposal to give political appointees greater authority over grant decisions and weaken the role of scientific peer review. In a stopgap spending bill released by Senate appropriators, Democrats and Republicans joined in adding a provision that would prevent the OMB rule from taking effect until at least December 11, while Congress negotiates broader government funding measures. The proposal was originally slated to go into effect on October 1, but opposition from appropriators, including Senate Appropriations Chair Susan Collins, slowed the path forward.

IMPLICATIONS: This development suggests that months of public opposition and advocacy from the advocacy and scientific community may be beginning to influence policymakers. The Senate’s intervention is one of the first signs that resistance to the OMB proposal extends beyond the scientific community and into both parties in Congress. However, the delay is only temporary, and, if implemented, the rule could fundamentally reshape the US research enterprise by injecting political considerations into grantmaking, weakening peer review and undermining the international collaborations that drive progress against HIV, emerging infectious diseases and other global health challenges.

US Senate Confirms New Centers for Disease Control and Prevention Leader

The US Senate confirmed Erica Schwartz as the next director of the Centers for Disease Control and Prevention (CDC), after a year without a confirmed leader. Schwartz is a former deputy surgeon general and chief medical officer of the US Coast Guard. During her controversial confirmation hearing, she agreed to uphold scientific integrity and transparency, but did not challenge or speak to RFK Jr.’s position on vaccines and other controversial health policies.

IMPLICATIONS: Schwartz will take over the agency, which has seen a major reduction of its workforce, political battles over vaccine policy and mounting public health threats. While her appointment to the leadership post may bring some stability, many public health leaders question whether she is able to lead an independent CDC outside of the Administration’s political pressure as RFK Jr. continues to attempt to reshape federal health policy. Will Schwartz defend scientific evidence, particularly on vaccines, infectious diseases and outbreak preparedness? That is the question the many advocates and leaders are waiting to answer.

International AIDS Conference Wraps Up: Rising Above to Meet the Moment

The International AIDS Conference (AIDS 2026) concluded last Friday. It was marked by extraordinary scientific progress and growing political and financial uncertainty. New data showed the consequences of the US Administration’s retreat from global health leadership, with nearly 2,000 HIV service sites closed and prevention programs for key populations severely disrupted following cuts to PEPFAR and other foreign-aid programs. While delegates applauded Merck’s decision to license its investigational monthly oral PrEP pill, alimatravir, to generic manufacturers before Phase 3 trials are complete, leaders warned that supply shortages threaten the rollout of injectable lenacapavir for PrEP (LEN) and called attention to the exclusion of Latin America in access agreements despite its central role in clinical research. Other major advances in prevention, treatment and cure, including innovative community-based and pharmacy delivery models for long-acting prevention and news of two more patients with HIV and cancer were cured following stem cell transplants for cancer treatment were presented showing the promise of new technologies, but the conversation focused on whether they can be developed and deployed feasibly and at scale.

IMPLICATIONS: AIDS 2026 underscored a stark reality: the greatest barriers to ending HIV are increasingly political rather than scientific. Across sessions on prevention, vaccines, cure research, artificial intelligence and service delivery, one theme emerged repeatedly: innovation alone is not enough. As AVAC’s Mitchell Warren shared in a commentary, translating scientific breakthroughs into public-health impact will require sustained political commitment, financing, supply chains and delivery systems that can move with speed, scale and equity. As governments cut funding and retreat from longstanding partnerships, the conference made clear that communities are not merely beneficiaries of the HIV response, they are its leaders, and the future of the epidemic will depend on their ability to shape the research, policies and programs that come next.

Global Health Watch: First real-world PEPFAR disruption data, long-term LEN results, US foreign assistance, HIV supply chain vulnerabilities

Issue 78

New evidence ahead of next week’s International AIDS Conference continues to illustrate the challenges and opportunities facing the global HIV response. This week’s issue covers the first real-world evidence of PEPFAR disruptions, new data reinforcing the long-term potential of lenacapavir for HIV PrEP (LEN), the emerging US foreign assistance architecture and a timely analysis of the vulnerabilities facing HIV medicine supply chains.

First Real-World Evidence of PEPFAR’s Disruptions

Ahead of the AIDS 2026 conference starting this weekend in Brazil, amfAR released the first real-world evidence—not modeling—of the impact of the dismantling of PEPFAR-supported HIV prevention programs through a survey of 1,700 PEPFAR service delivery sites. In their report, amfAR found that three-quarters of US-funded organizations surveyed terminated services to those at highest risk from HIV — sex workers, men who have sex with men, transgender people and people who inject drugs and that “among partners providing prevention services, 43% permanently stopped at least one prevention activity, with the deepest cuts to condom programming and PrEP.” CHAI also shared new analyses of PEPFAR program data that found a 14.2% decline in children receiving PEPFAR-supported HIV treatment in 2025 compared with 2024, with five countries showing steeper-than-expected declines. The findings closely align with AVAC’s analysis showing steep declines in PEPFAR-supported PrEP initiations.

IMPLICATIONS: These findings document “not a collapse, but the narrowing of PEPFAR services concentrated among the populations and programming that, in the long term, often decide whether epidemic control is won or lost,” amfAR’s Elise Lankiewicz shared at a July 21 press conference. “Trying to carve out and cancel certain awards had ripple impacts throughout the whole program.” The system that is left “is really a treatment-heavy model, which isn’t really conducive to controlling the HIV epidemic long-term.” Lankiewicz’s remarks illustrate the urgency to reinstate and immediately scale-up the suite of lost prevention services provided by PEPFAR to all those vulnerable to HIV, as a vital component to the program’s vision for sustainability and epidemic control. The fiscal urgency was further emphasized in US Senator John Cornyn’s call for the Administration to release $1.3 billion in Congressionally-appropriated PEPFAR funding, which underscores the critical role of Congress in ensuring people remain on treatment, prevention services reach those at greatest risk and new infections continue to decline.

52-Week Data Strengthen the Case for Lenacapavir for HIV PrEP

New results from the open-label extension studies of the PURPOSE 1 and PURPOSE 2 trials testing lenacapavir for HIV PrEP show that the six-monthly injectable can deliver sustained HIV prevention. The studies answered three critical implementation questions: Would people choose LEN over daily oral PrEP? Would they continue returning for injections every six months? Would the remarkably high efficacy seen in the randomized trials be sustained? The answer to all three was yes. Most participants chose to remain on or switch to LEN, adherence exceeded 90%, and the high level of protection was maintained a year after the original trial results, with just one HIV acquisition reported.

IMPLICATIONS: As AVAC’s Mitchell Warren argues in a new journal commentary, “the central challenge is no longer the absence of effective tools, but the failure to deliver them equitably and at scale.” The open-label data should give policymakers, implementers and communities greater confidence that scaling-up access and investments in national rollout can translate into sustained real-world impact. To help, Unitaid announced Thursday an additional US15 million to accelerate the introduction, adoption and uptake of breakthrough HIV prevention products, including long-acting PrEP, across diverse regions. This all reinforces a growing theme across the AIDS 2026 conference next week: scientific breakthroughs alone will not end the epidemic. Success will depend on sustained financing, accelerated policy actions, robust community engagement and resilient delivery systems that can ensure people who want HIV prevention options can actually access them.

Foreign Assistance After USAID

Devex published a comprehensive analysis of the US Administration’s evolving foreign assistance architecture in the 18 months since the dismantling of USAID. In line with the recent reflections from global health leaders, the piece concludes that US foreign assistance is coalescing around three priorities: humanitarian response, global health and commercial diplomacy. These pillars are being delivered through a smaller, more centralized system that emphasizes bilateral partnerships, country burden-sharing and funding through a limited number of “trusted, vetted” implementing partners.

IMPLICATIONS: How this new architecture will function in practice is in question. Emily Bass reports that the US Department of State is increasingly relying on sole-source, fixed amount awards (FAAs) issued under a broad class waiver to support the transition. While the approach may help sustain HIV and other health services as the Administration finalizes bilateral health implementation plans, it raises questions about transparency, competition and oversight. FAAs tie payments to predefined milestones as opposed to actual costs, so they shift financial and operational risk to the organizations responsible for delivering programs. Whether these enlisted organizations can take on these risks while maintaining essential HIV health services is a major question to be answered.

Global Health Watch: Global Governance Shifts, ACIP Charter + Vaccine Policy, PEPFAR Transition

Issue 75

As many in the United States pause to commemorate Independence Day – and, hopefully, re-commit to the fundamental principles of democracy – the global health community continues to navigate the far-reaching effects of US policy decisions. Institutions are changing, governance is being redefined and the systems that have underpinned the global HIV response are being reshaped. This issue covers developments in global health governance, the continued restructuring of US vaccine policy and growing concerns that PEPFAR’s transition is outpacing the systems needed to sustain it.

Global Governance Shifts

The last two weeks, and the week ahead, mark key moments for global health governance with implications for the HIV response. Last week, for the first time in 25 years, UN Member States adopted a new Political Declaration on HIV/AIDS with a vote (with the US voting no), as opposed to the historic consensus of all past declarations. This week, both the UNAIDS Programme Coordinating Board (PCB) and the Unitaid Executive Board met against the backdrop of financial strain and uncertainty. Conversations and debates about their future roles continued, including questions about UNAIDS’ future structure within the UN system. Next week, the Global Fund Board will meet as it prepares to select its next Executive Director who is expected to shape the Fund’s strategic direction during one of the most challenging periods in its history.

IMPLICATIONS: In all these meetings, there is a reassessment of each entity and a reenvisioning of how global health organizations will coordinate, finance and sustain the HIV response in an era of constrained resources and shifting geopolitical priorities. As countries work toward the 2030 goal of ending AIDS as a public health threat, the decisions made by these governing bodies in the coming weeks will help determine whether and how the HIV response maintains the leadership, financing, accountability, collaboration and civil society engagement needed to carry the response forward.

US HHS Rewrites ACIP Charter, Further Reshaping US Vaccine Policy

The US Department of Health and Human Services (HHS) issued a new charter for the CDC’s Advisory Committee on Immunization Practices (ACIP), broadening the Committee’s mandate and reducing the qualifications required for membership. Previously, vaccine expertise was a requirement, but the revised charter states that members should collectively represent a “balanced range of scientific, clinical, and public health expertise”. The new charter also expands the Committee’s focus beyond reviewing vaccines to considering alternative approaches to disease prevention.

IMPLICATIONS: This is the latest step in the restructuring of ACIP. By broadening the Committee’s remit and redefining membership qualifications, vaccine policymaking is further politicized and vaccine confidence continues to erode. This creates further instability and uncertainty for vaccine manufacturers, healthcare providers and immunization programs worldwide.

PEPFAR In Transition

Two commentaries this week recognize the breaking point to which PEPFAR is nearing. The Health Security Policy Academy argues that despite the temporary extensions, which have kept and continue to keep parts of PEPFAR operating, the US Department of State has not yet built a viable implementation system to keep HIV treatment, supply chains, laboratories and community programs working. At the same time, Emily Bass, Yvette Raphael, Nono Eland and colleagues at Physicians for Human Rights argue in Think Global Health that the planned phase-out of all US PEPFAR support for South Africa by early 2027 is not a routine transition to country ownership, and caution that this accelerated withdrawal risks severed disruption to HIV prevention, surveillance, research and community programs that have long depended on US partnership.

IMPLICATIONS: Without a clear implementation strategy and carefully managed country transitions, these abrupt changes to PEPFAR threaten essential HIV services. A more deliberate, evidence-based approach that preserves critical infrastructure while supporting long-term country ownership is needed. “The dismantling of USAID showed what happens when the Administration destroys an operating system before a replacement exists. That chaos was not an accident, but it was sudden,” writes the Health Security Policy Academy. It remains even less clear what happens next with leadership transitions at the State Department: Jeremy Lewin who has led the State Department’s foreign aid bureau for the last year is heading to the National Security Council, and is being replaced by Andrew Veprek, who has pushed immigration and refugee restrictions at the State Department – and confirmation hearings are yet to be scheduled for Johnny Figueroa as the ambassador-at-large for global health security and diplomacy and PEPFAR.

Global Health Watch: Restructuring PEPFAR, Political Control Over Science; FDA + African Medicines Agency MoU

Issue 73

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.

A ‘perilous moment’ for the response to HIV

A new UNAIDS report released ahead of next week’s United Nations General Assembly’s High-Level Meeting on HIV/AIDS shows that external funding cuts, a strong push back on human rights and under investment and under prioritization of HIV prevention and community services are threatening to reverse years of gains in the AIDS response.

HIV Prevention Advocates Applaud South Africa’s Introduction of Lenacapavir for PrEP

Call on Donors and Governments to Accelerate Access to Deliver Actual Impact

In a landmark moment, South Africa today became the 9th African country to introduce lencapavir (LEN) for HIV prevention. South Africa’s introduction of LEN is especially significant given the country’s central role in shaping the regional HIV response and the global PrEP market. As the largest PrEP market in the world, South Africa’s leadership can help drive the demand, volume, market confidence and lower prices needed to accelerate equitable access across the continent and the world. HIV prevention partners AVAC, Advocates for the Prevention of HIV in Africa (APHA), and Access Bridge welcomed today’s news of increased commitments and support from the Global Fund, while calling for further ensure access is realized and impact achieved.

“Today is a breakthrough. Not only for our country and the African continent, which continues to carry some of the world’s largest HIV burdens, but for the global HIV response. Access to LEN allows us to reimagine prevention, especially for young people and adolescent girls and young women who need more choices that fit their lives. It is important to centre our efforts around girls and young women who need to be the focus of our efforts. We must move with urgency to ensure that everyone who could benefit from lenacapavir can do so,” said Yvette Raphael, Executive Director of Advocates for the Prevention of HIV in Africa (APHA) and co-chair of the African Women’s Prevention Community Accountability Board (AWPCAB).

“Today is a sign of what is possible when communities, governments, and partners work together. LEN will offer my generation the chance to protect their health with greater freedom and confidence. We must now make sure this innovation reaches the people who need it most—quickly, equitably, and without barriers. Today is exciting, but it is also a call to action for all of us,” said Lerato Morulane, APHA Ground Force coordinator.

During the launch event, the Global Fund announced that with additional backing from the Children’s Investment Fund Foundation (CIFF), it will scale-up support for South Africa’s LEN roll-out, increasing funding from $29M to nearly $70M to support this more ambitious effort. This contribution to the Global Fund goes toward their joint commitment with PEPFAR to ensure access to LEN for at least three million people over three years – a more solid start than with previous PrEP introductions, but still below the levels needed to deliver impact.

In July 2025, AVAC published a market assessment that the world could go much faster than existing commitments allow and reach at least 1.5 million people with LEN in just one year in low- and middle-income countries if resources were made available, and reach over seven million in three years, if resources were available.

“Lenacapavir has transformational potential for HIV prevention, and today’s launch is another step in the right direction,” said Mitchell Warren, Executive Director of AVAC. “But additional donor investments are urgently needed as the field is still nowhere near what the market can bear and what is needed for impact. A meaningful volume commitment of at least four million LEN users in two years is both possible and has the potential to unlock faster access, strengthen market confidence, and accelerate access to prevention for communities that need it most. Ultimately, LEN must reach more than five million people per year to have real impact, build a sustainable market, and drive prices down even further. Today’s announcement is progress, but we still need to go farther faster.”

LEN has been widely recognized as a transformative HIV prevention option, with the every-six-month injection providing highly effective protection. However, translating the scientific breakthrough of LEN into population-level access and impact requires coordinated action across many sectors, including financing, manufacturing, pricing, regulatory, and delivery.

“Today represents another important milestone, but now we need to roll up our collective sleeves and get to work,” said Wawira Nyagah, Executive Director of Access Bridge. “South Africa has an essential role to play in building the global market for LEN and driving the volumes needed to lower prices, strengthen supply, and accelerate access worldwide. To realize the full potential of this innovation, all stakeholders must work together with even greater urgency, ambition, and a commitment to speed, scale, and equity. The opportunity is in front of us; now we must seize it. To see LEN truly succeed, programs must be designed with communities at the centre and that commitments translate into real access for the people who need it. Access Bridge is working across countries in Eastern and Southern Africa to ensure countries are equipped to meet this moment.”

AVAC and Access Bridge have called on stakeholders to meet the current moment of scientific opportunity and public health need with bolder ambition. The past decade of PrEP programs have highlighted numerous lessons on how to get LEN rollout right as part of comprehensive HIV prevention programs so that today’s announcement translates into real-world impact. Key considerations include:

Today’s announcement builds on prior commitments from the Global Fund and PEPFAR, as well as investments from the Gates Foundation and Unitaid to accelerate development and access to generic LEN at lower prices. With generic LEN likely entering the market in the first half of 2027, now is the time to strengthen and grow the market with Gilead’s supply: the faster the market grows, the more infections that can be averted at lower cost.

“Commitments are important, but orders are essential. In Gilead’s own words, they can produce far more if orders are made,” said Warren. “Especially for 2027, clear timelines and ambitious orders for both originator and generic supply will be critical to avoid gaps in care of current LEN users and to expand the reach of this innovation.”

HIV Vaccine Awareness Day Resources and Perspectives 

On this HIV Vaccine Awareness Day, AVAC is sharing resources and perspectives on the HIV vaccine pipeline, the science behind neutralizing antibodies, the state of bNAb combinations, and the broader state of HIV research amid the destruction and devastation of science and the HIV response.  

While an HIV vaccine remains elusive, in the current environment of threats to science, vaccines and the global HIV/AIDS response, HVAD serves as an important moment to re-commit to HIV vaccine R&D and the essential role of discovery science as part of a comprehensive, integrated and sustained response.

AVAC and Partners Launch New STI Advocacy Agendas in Kenya, South Africa and Zimbabwe

AVAC and partners are proud to share three new national sexually transmitted infections (STIs) advocacy agendas for Kenya, South Africa and Zimbabwe, providing coordinated agendas to elevate STIs as a national health priority and accelerate actions on R&D and delivery of STI vaccines, diagnostics, prevention and care. Join us Tuesday, 12 May to learn more about these country-led advocacy agendas.

STIs remain widespread, underdiagnosed and persistently underprioritized around the world. In Kenya, South Africa and Zimbabwe, gaps in awareness, surveillance data and diagnostics, along with challenges delivering essential testing and treatment services, continue to limit effective and equitable STI prevention, treatment and care. This persists despite the availability of proven prevention tools, including vaccines and diagnostics, and growing evidence of the health and economic consequences of inaction.  
 
The country-specific agendas highlight shared priorities in response to these gaps: strengthening surveillance and data systems; expanding access to diagnostics; building health workforce capacity; and preparing health systems for emerging tools such as additional STI vaccines.  
 
These advocacy agendas were developed by partners in Kenya, South Africa and Zimbabwe through cross-country collaborations that brought together researchers, advocates, civil society organizations and policy experts. Over several months, they analyzed the STI landscape in each country and identified the most urgent opportunities for policy change and investment.

“Together, these three agendas lay the groundwork for a new cross-country STI advocacy network in East and Southern Africa,” said Alison Footman, PhD, senior program manager of STIs at AVAC. “Each agenda reflects country-specific priorities, but, collectively, they elevate community voices, strengthen policy engagement and build regional momentum to ensure STI prevention, diagnosis and care receive the sustained attention they deserve.”

Read More About Their Priorities

Advancing Diagnostics, Data and Community-Led Advocacy

“Kenya’s STI advocacy agenda responds to a substantial STI burden affecting both the general population and key populations,” said Felix Mogaka, MBChB, Kenya advocacy partner. “Our work and those of our partners show that a significant proportion of infections remain undiagnosed or untreated, in part because Kenya continues to rely heavily on syndromic management for STI treatment, an approach that relies on self-reported symptoms and can miss many asymptomatic infections.” 
 
Kenya’s advocacy agenda calls for updating national STI policies, strengthening health workforce capacity and ensuring that community organizations play a central role in advocacy and awareness.

Bridging Research, Policy and Implementation 

“STIs in South Africa have too often been treated as a side issue in public health discussions,” said Alex de Voux, PhD, South Africa advocacy partner. “Our vision is to build a stronger, more coordinated response, one where communities are informed and empowered, health providers are supported with the right tools, and sexual health is recognized as a fundamental part of public health.”  


South Africa’s agenda identifies opportunities to expand access to credible STI information, strengthen advocacy capacity across communities, healthcare providers and policymakers, and promote a positive, rights-based approach to sexual health that improves prevention, diagnosis and care.

Strengthening Evidence, Integration and Investment

“Zimbabwe has an opportunity to strengthen its STI response by bringing greater alignment between national leadership, healthcare providers and communities,” said Chido Dziva Chikwari, PhD, epidemiologist and global health practitioner in Zimbabwe. “When national policies, frontline care and lived experience are connected, Zimbabwe will be far better positioned to improve STI prevention, diagnosis and care.”  
 
Zimbabwe’s agenda calls for increased advocacy, expanded diagnostic testing, greater integration of STI services with other health programs and stronger domestic financing for STI prevention and research.

A New Platform for STI Advocacy

The launch of these agendas marks the start of a sustained cross-country STI advocacy network in East and Southern Africa to raise the profile of STIs within national and global health agendas.  
 
AVAC and its partners will continue working together to amplify the agendas, engage policymakers and mobilize greater investment in STI prevention and care.

“These agendas show what is possible when advocates, researchers and communities come together to define solutions,” said Footman. “We are incredibly proud of the leadership and commitment of our partners who developed these priorities. The next step is ensuring that governments, donors and global health partners act on them.”

One year ago, we sued the US Government…

Today marks one year since AVAC and the Journalism Development Network worked with the Public Citizen Litigation Group to sue the US President, the State Department, the US Agency for International Development (USAID), and others, seeking emergency relief from a sweeping freeze on foreign assistance issued by the incoming administration that abruptly halted life-saving global health and development programs. A parallel case was brought by Global Health Council and partners and assigned to the same District Court judge, underscoring the broad concern across the global health community.

Twelve months later, these cases have come to symbolize a much larger question: whether the executive branch can override Congress’s constitutional authority over federal spending and dismantle decades of bipartisan foreign policy with the stroke of a pen, and whether the courts and Congress will fulfill their responsibilities to serve as checks on unbridled executive power.

The past year has laid bare the real-world consequences of unchecked executive action, threatening lives, destabilizing global partnerships, and undermining the United States’ credibility as a reliable partner. 

An early ruling in AVAC’s case successfully unlocked nearly $2 billion in US government payments for work already completed, affirming that the executive branch cannot refuse to spend money appropriated by Congress. But over the course of 2025, appeals by the administration, ultimately backed by the US Supreme Court, ran down the clock on $4 billion in already-appropriated funds for the 2025 fiscal year, allowing them to expire.  

While the Supreme Court’s ruling did not resolve the underlying constitutional questions, the decision was narrow and the Court left open the opportunity for further argument on the merit of the questions involved. In November 2025, a joint statement to the District Court requested to pause the cases, awaiting the outcome of other relevant court decisions.   

The AVAC and GHC cases remain active, but lawsuits alone cannot restore what was lost—or undo the long-term harm caused by the sudden dismantling of global health systems. 

The actions by this administration demand more than concern. This moment demands public accountability, sustained Congressional oversight, and durable legislative safeguards. Global health and equity require champions willing to fight for lives and livelihoods, and for what’s right. We cannot accept this as the new normal, and we must insist that Congressional authority, democratic governance, and the lives they protect still matter.

Global Health Watch: Reflecting on 1 Year of Chaos and What’s Next, Congress Pushes Back, the Future of WHO, US Undermines African Authority

Issue 52

This week marks 365 days of disruption and chaos across global health, with many organizations and journalists reflecting on one year after the foreign aid freeze and what the future of global health looks like. This week also saw the US Congress beginning to reassert its role on health funding, ongoing US disengagement from WHO, and new reporting on the hepatitis B vaccine trial in Guinea-Bissau.  

We are also watching closely for news of an expanded Global Gag Rule, that is reportedly coming out later today, just as this issue goes to press. It is anticipated that this new gag will include a dramatic expansion beyond abortion and now underscore the US administration’s war on gender, diversity, equity and inclusion. We’ll cover this in next week’s Global Health Watch; the struggle, most definitely, continues.

365 Days of Chaos and Disruption, What Comes Next for Global Health 

This week marks one year since the US Presidential administration issued a deeply cruel executive order freezing foreign assistance, halting billions of dollars in already-approved funding under the bad-faith claim of a “90-day review”. What followed was not a brief pause, but a drawn-out, chaotic disruption that stopped life-saving work across the globe, shutting down valuable organizations, and harming lives, health, and livelihoods. And that was just the beginning of a year of chaos. Many organizations and media coverage noted a growing recognition that the past year’s disruptions to global health were not just destructive, but catalytic, forcing a reckoning with how systems are built and for whom. Reporting from Bhekisisa reflected on how the sudden halt in US HIV funding exposed deep vulnerabilities in over-reliance on external aid, while also accelerating conversations about domestic financing, integration, and sustainability in the HIV response moving into 2026. At the same time, analyses from Health Policy Watch, Science, Nature, and The Lancet laid bare the human and scientific costs of abrupt policy shifts, shuttered programs, fractured research networks, and lost trust, while underscoring that simply restoring old funding streams will not be enough to meet future challenges. 

IMPLICATIONS: Together, these stories and analyses point to the need to rethink and rebuild with stronger country ownership, diversified and predictable financing, resilient research institutions, and governance structures that prioritize equity, accountability, and community leadership. Rather than recreating the same architecture, reimagined global health systems must be less dependent on external donors and political ideology. As Global Health Watch has tracked for 52 weeks, the path forward is not about returning to the pre-foreign aid freeze status quo, but about using this period of disruption to construct a more durable, equitable, and responsive global health architecture. As Canadian Prime Minister, Mark Carney, said so clearly at this week’s World Economic Forum in Davos, Switzerland, “Nostalgia is not a strategy.”

Congress Steps Up In Defending Domestic and Global Health

The US Congress is beginning to reassert its constitutional role in shaping federal spending. The joint House and Senate FY26 funding bill released last week covering foreign operations would maintain funding for core global health priorities, including HIV, tuberculosis, malaria, polio, family planning and reproductive health, neglected tropical diseases, Gavi, and UN agencies such as UNAIDS, UNICEF, and UNFPA. This week, legislators rejected nearly $2 billion in proposed cuts to US domestic HIV and related programs through the Labor, Health and Human Services Education and Related Appropriations Act (LHHS), a “major victory” credited to sustained advocacy by people living with HIV, advocates, and service providers. The proposed bill largely preserves funding for domestic public health and biomedical research. As AVAC’s Suraj Madoori said in a statement, “These crucial wins for global and domestic HIV now require us to not hold back, and urge Congress to swiftly approve all the FY26 bills, push the President to sign them, and for us to ensure accountability in the administration to spend and implement this lifesaving funding as instructed by the people and those who represent us in Washington D.C.” 
 
IMPLICATIONS: Together, these bills signal a return to a bipartisan appropriations process and, if enacted, provide a basis to push back against unilateral cuts by the administration. They also signal bipartisan pushback against attempts to cut health and scientific research investments. By rejecting the steep cuts proposed by the administration, they stabilize lifesaving programs and protect the research enterprise. The House passed the bills on Thursday, and the focus now shifts to the Senate, which must pass the bills by January 30. Then onto the President to sign, and, most critically, for the administration to actually spend all Congressionally appropriated funds.

US Disengagement and the Future of WHO

This week also marks one year since the US announced its intended departure from World Health Organization (WHO). Debate over its future and the US’ role within it intensified as pressure from parts of the administration collided with growing concern over the consequences of disengagement. US officials and policymakers aligned with the “America First” strategy call for WHO to be fundamentally reformed or replaced. Analysts note that the US remains a formal member of WHO until debts are paid. Meanwhile, the US administration continues to withhold funding and delay payments, leaving millions of dollars in unpaid US obligations.  
 
IMPLICATIONS: The current state, where the US remains technically engaged but substantively absent, poses serious risks for global health governance, disease surveillance and pandemic preparedness. As analyses from CSIS underscores, WHO reform is both necessary and possible, but meaningful reform requires constructive engagement, predictable financing, and political leadership, not abandonment.

Hepatitis B Vaccine Trial in Guinea-Bissau Undermines African Authority

Reporting this week is exposing a pattern of US actions that show deep disregard for African public health leadership, ethical research standards, and sovereignty. The US-funded hepatitis B vaccine trial in Guinea-Bissau is at the center of this. As we reported in previous weeks, the unethical trial would delay birth-dose vaccination for thousands of newborns despite overwhelming evidence, and WHO guidance, that immediate vaccination saves lives. According to Rolling Stone, the study was championed by US officials aligned with anti-vaccine ideology and advanced even as Africa CDC officials raised alarm and indicated the trial should be halted. At the same time, the US administration has been marginalizing Africa CDC more broadly, cutting engagement, undermining its authority, and sidelining African institutions in favor of unilateral decision-making. This is being reinforced, as The Guardian reports, by members of the US administration urging US diplomats to emphasize American “generosity” to African leaders even as USAID programs are shuttered and health funding withdrawn. 
 
IMPLICATIONS: Together, these developments signal a dangerous erosion of respect for African expertise, autonomy, and ethical authority in global health. Pushing forward research designs that would withhold proven interventions—while dismissing objections from Africa CDC and African scientists—revives patterns of extractive and unethical research long condemned by the global health community. Undermining Africa CDC while advancing ethically dubious trials weakens trust, damages partnerships, and threatens progress against hepatitis B, HIV, and other diseases where Africa has led with scientific excellence.

Global Health Watch: A Year That Reshaped Global Health

The Lancet journal ended the year with a provocative editorial – 2025: an annus horribilis for health in the USA. But sadly, it was not just in the US; it has been a year of chaos and disruption globally. This 49th issue of Global Health Watch looks back—like many news stories this week—across 2025 to highlight the most consequential decisions, disruptions, and debates that defined the year and will continue to shape what comes next.

On the first day in office, the new US Administration issued a sweeping foreign aid freeze that halted life-saving global health and HIV programs, severed active grants, research underway and cost millions of people their lives and livelihoods. In less than a month, AVAC responded suing the President, the State Department and the US Agency for International Development (USAID). The Global Health Council also led a similar lawsuit challenging the freeze as unlawful and harmful. Together, the two cases argued for months in various courts that the foreign aid freeze not only jeopardized health as a human right but also bypassed congressional authority and undermined trust in US leadership. Ultimately, the cases unlocked millions of dollars of development assistance for work done in January and February, but millions more dollars expired at the end of the fiscal year in September. The cases are ongoing and as important as ever, both to restore foreign assistance and to re-assert that it is Congress (and not the President) who has the power of the purse.

Research Under Assault 

Science faced underfunding and systematic destabilization in 2025. In just one month under the new US Administration, the National Institutes of Health (NIH) abruptly canceled approximately 1,800 research grants. By April, mass layoffs and forced reassignments across Health and Human Services (HHS) agencies, including the Centers for Disease Control and Prevention (CDC), NIH, and US Food and Drug Administration (FDA), further crippled each agency’s capacity and expertise. A proposal to drastically cut the overall NIH budget and consolidate its 27 institutes was soon introduced along with the fiscal year 2026 budget, which proposed an $18 billion cut from the NIH and $1.5B cut in HIV prevention. Around the same time, the NIH signaled a major shift away from investments in basic science and clinical research, undermining the discovery pipeline that fuels future breakthroughs. Then, in November, HHS ordered the CDC to phase out all “non-essential” nonhuman primate research, threatening foundational preclinical studies, including those that have been pivotal to HIV PrEP and PEP, amongst many other health priorities. These actions were compounded by a pause or effective ban on some international research collaborations, a proposed cap on indirect cost rates that support core university infrastructure, and changes to the scientific review processes, together weakening the systems that sustain rigorous, independent research.

The Cruel Irony of the Best Shot at HIV Prevention

Despite all the chaos, 2025 offered remarkable milestones in HIV prevention science, and a stark illustration of the contradictions shaping global health. Injectable lenacapavir for PrEP (LEN), the six-month injectable, which provides nearly complete protection against HIV infection, moved with unprecedented speed from regulatory approvals and guidelines to real-world introduction. South Africa and Zambia authorized LEN within months of US and EU regulatory approvals; the World Health Organization (WHO) rapidly issued guidance and prequalification; and initial LEN delivery began in Brazil, Eswatini, South Africa, and Zambia, setting the stage for expanded access in 2026. At the same time, efficacy trials began of the next promising PrEP option, the monthly oral candidate MK-8527, reinforcing what’s possible when innovation, evidence, and advocacy align.  
 
Yet, all this scientific momentum occurred alongside the deepest assault on global health and the systems that make it possible. The cruel irony of this moment is that as the science breaks barriers, the infrastructure meant to support discovery, evaluation, and equitable delivery is being weakened, threatening the very gains the field has fought decades to achieve. As AVAC has emphasized, the greatest opportunity in HIV prevention lies in speed, scale, and equity.

Attack on Vaccine Science 

Actions in the last 11 months have eroded evidence-based policy, disrupted institutional capacities, and deepened mistrust and uncertainty in vaccine science. In May, NIH’s National Institute of Allergy and Infectious Diseases (NIAID) announced that funding for the Consortia for HIV/AIDS Vaccine Development (CHAVD) would end after the current grant cycle in June 2026 — eliminating $67 million annually and about 10% of global HIV vaccine research funding. Then, $500 million in Biomedical Advanced Research Development Authority (BARDA) grants for research and development of the mRNA vaccine platform were soon cancelled, and members of the CDC’s Advisory Committee on Immunization Practices (ACIP) were replaced. The US also stopped supporting Gavi, the vaccine alliance, and language on the CDC website was replaced with anti-science and anti-vaccine sentiment. As AVAC said in an August statement, “These actions dangerously sow vaccine disinformation and mistrust, which has proliferated since the COVID-19 pandemic. Dangerous ideology results in dangerous policymaking, putting many lives at stake and complicating efforts to both discover and implement clinical and cost-effective interventions to make America and the world healthier, safer, and more prosperous.”

Changing Global Health Architecture 

As rising nationalism, geopolitical tensions, and funding retrenchment intensify, the architecture of global health and how countries engage in it and with one another is being fundamentally reshaped. Longstanding multilateral systems are giving way to a more fragmented, country-to-country model under the US America First Global Health Strategy. The strategy prioritizes bilateral health Memorandums of Understanding (MoUs) with individual countries in exchange for funding support, data sharing, and pathogen access, signaling a major recalibration away from traditional multilateral institutions and frameworks. Meanwhile, the US stepped back from longstanding global health platforms including an unprecedented absence at the World Health Assembly, withdrawal from the WHO, and diminishing support for joint initiatives like Gavi, the vaccine alliance. Civil society and advocates are actively debating what this means for shared goals and equity in global health, even as institutions like WHO and UNAIDS explore how to adapt in a rapidly evolving landscape.
