2025 has been a whirlwind year for global health. In the United States, we've seen the integration of the US Agency for International Development (USAID) into the Department of State, transformation at the Department of Health and Human Services (HHS), and a complicated and prolonged budget process. Globally, we've seen setbacks and progress in HIV and malaria, an evolution at the World Health Organization (WHO), a multilateral win with the Pandemic Agreement adoption, and African partners stepping up to boost autonomy.As the year draws to a close, GHTC is reflecting on the innovations, policy shifts, and pivotal moments that defined 2025 and what they signal for the years to come.US global health leadership in transitionOn day one of his second term, President Donald Trump initiated an effort to realign US foreign assistance programs with the goal of making America safer, stronger, and more prosperous. This effort started with an overhaul of USAID, triggering a series of layoffs, stop-work orders that turned into award terminations, and withdrawals from multilateral partnerships, culminating in the agency’s official integration into the State Department on July 1.While this suspension and termination of USAID programs disrupted critical research projects and health services worldwide earlier this year, in September, the State Department unveiled the America First Global Health Strategy, which outlines a plan to reshape the US government’s global health programming, presenting opportunities for global health research and development (R&D).The new strategy centers multiyear bilateral agreements with countries while reducing ties with nongovernmental organizations and narrowing health focal areas. While critical questions remain on implementation—including on whether the agency still retains needed expertise and how it will coordinate with interagency technical partners like the US Centers for Disease Control and Prevention (CDC)—the strategy’s focus on integrating aid more directly into national health systems is a step forward in improving sustainability and self-reliance. The strategy also raises the exciting possibility that funds could be used to support “innovative, breakthrough technologies.”  Building on USAID’s successes and shortcomings in that space, the department has a clear opportunity to establish a centralized R&D fund—in complement to bilateral agreements—to invest in innovative tools that could leapfrog global health progress. Through collaboration with global health stakeholders and interagency partners, State could reshape US global health programs to continue to save lives; foster funding beyond US government resources, including through partner nations; and promote shared security and prosperity.Overhaul of US scientific and public health infrastructureThe United States has long been a leader in global health R&D and science more broadly, with American researchers, universities, companies, and patients benefiting. In 2025, sweeping changes at HHS reshaped America’s public health and research infrastructure. These far-reaching reforms aimed to advance administration priorities of promoting “gold standard science,” improving efficiency, transparency, and oversight and realigning investments to match administration objectives. At the National Institutes of Health (NIH) and CDC, these changes have included significant staff departures, among them seasoned leaders, and the appointment of many officials who were previously critics of these agencies. It has also included new policies to overhaul oversight of foreign awards and cap indirect costs, changes to longstanding vaccine guidance, and the terminations of numerous awards, including a wind-down of mRNA vaccine development activities. The speed and scale of these changes have raised concerns across the biomedical research and public health communities. While thoughtful reforms could yield benefits, experts warn that current actions risk driving US scientists abroad, disrupting promising clinical trials, weakening the pipeline of new tools, eroding trust in public health guidance, and weakening the structures that have sustained US scientific leadership. US budget swings and shutdowns2025 began with a race to fund the government, with President Trump signing the fiscal year 2025 budget into law in mid-March. While the budget maintained global health R&D-relevant funding lines at prior levels, it funded a government that now looked significantly different after sweeping layoffs and restructuring. Months later, the administration issued its budget request, proposing significant cuts and a restructuring of global health and research programs, reflecting far-reaching changes it had already begun to enact.In June, the administration proposed a request to rescind billions in funding for foreign aid. Though Senators stepped in to remove cuts to global programs for HIV/AIDS and several other health areas, the package ultimately became law, cancelling $500 million in previously appropriated global health funds and raising the possibility that this administration will continue to use rescissions as a tool to withdraw funding.  By late summer, Senate and House appropriators advanced interim funding bills that included higher-than-expected funding for global health and medical research, maintaining funding proposed for elimination by the administration. But then stalled negotiations triggered the longest-ever government shutdown, during which the administration implemented unprecedented furloughs and layoffs that affected critical staff at public health and health research agencies.While the shutdown ended on November 12, pushing the funding fight until January, and most associated layoffs were reversed, uncertainty about future funding for global health R&D persists, especially with a deeply divided Congress and the potential of further recissions.A year of setbacks and breakthroughs in HIV and malaria effortsGlobal HIV/AIDS and malaria efforts faced major setbacks in 2025 as declining US and international donor support has threatened decades of hard-fought progress. Funding cuts could lead to millions of additional HIV and malaria cases in the coming years and has already stalled promising research advancing new HIV and malaria tools.Amid these challenges, the June approval by the US Food and Drug Administration of lenacapavir, a twice-yearly injectable drug for HIV prevention, marked a major milestone and a reminder of the incredible progress possible through strong support for research. Developed by Gilead and supported by NIH-backed research, the drug offers an alternative to daily pills or bi-monthly injections, making prevention more accessible and easier to maintain. Global partners are stepping up to expand access, and Phase 3 trials of a once-yearly version are planned.In November, Medicines for Malaria Venture and Novartis shared Phase 3 trial results for GanLum, a new drug found to be highly effective at treating malaria, including drug-resistant cases, and capable of blocking disease transmission. Pending approval, it could help counter rising resistance to current treatments.Other notable R&D advances in 2025 also targeted the growing threat of antimicrobial resistance, including a Phase 3 trial for a novel antibiotic targeting a dangerous antibiotic-resistant pathogen, support for what could be the first-ever vaccine for Escherichia coli, and efforts to harness artificial intelligence to transform antibiotic discovery. These breakthroughs underscore the importance of sustained R&D investment and the efforts to ensure new tools reach those who need them.WHO restructures amid budget shortfallFacing a severe budget crisis and pressure from member states to reprioritize programs, WHO launched a sweeping overhaul in 2025, cutting staff, slashing its budget, and reorganizing core functions. At its February Executive Board meeting, member states approved a $1.1 billion budget reduction, leaving a remaining $1.7 billion shortfall for 2026 and 2027, despite a recent increase to membership dues and appeals for voluntary contributions.In late April, WHO announced a plan to halve its senior leadership team and consolidate departments. Infectious disease and climate and health programs remain relatively well-resourced, and merging several disease-specific initiatives into a new division could strengthen certain programs. However, neglected tropical diseases and health emergency preparedness and response programs face sharp cuts, while reductions in regional and in-house expert posts may weaken global lab and surveillance networks and delay critical guidance, raising concerns about WHO’s outbreak response capacity.One core R&D function spared from the worst cuts was WHO’s prequalification (PQ) program, which evaluates medical products to support regulatory approval and rollout in countries with less advanced regulatory authorities. The program has marked some important achievements this year, launching a new portal to improve transparency for developers, introducing a new streamlined review and guidance process for TB diagnostics, and prequalifying lenacapavir for HIV prevention through a compressed process completed in just 36 days. As WHO and the broader United Nations system grapple with financial strain and diminished donor support, questions remain about the capacity to deliver on their mandate. A major outbreak could test the limits of this leaner system.Pandemic Agreement provides hope in challenging year for multilateralismAt the World Health Assembly in May, delegates adopted the Pandemic Agreement, a milestone win for global health after three years of complex negotiations. However, consensus on a pathogen and access-benefit sharing system was not reached, requiring member states to return to the negotiating table to finalize an annex for adoption at next year’s assembly. Persistent disputes over the voluntary or legally binding nature of participation signal tough negotiations ahead.While the Pandemic Agreement is a huge win, pushback from key countries and declining pandemic preparedness investments raise concerns about global readiness. Annex negotiations and the 2026 United Nations High-Level Meeting on Pandemic Prevention, Preparedness, and Response will further test international unity on this crucial topic.Meanwhile, 2026 brought notable R&D advances to strengthen our defenses against pandemic threats. The Coalition for Epidemic Preparedness Innovations launched the first-ever adjuvant library of 25 immune-boosting substances to improve vaccine effectiveness and awarded $17.3 million for Phase 2 trials of a promising Nipah vaccine, among the first candidates targeting the priority virus to reach this critical stage. IAVI’s vaccine candidate for Lassa virus, another virus with pandemic potential, was also found to be safe and effective in a first-in-human Phase 1 trial, marking further R&D progress against concerning disease threats.Partners step up to fill gaps and boost autonomyAmid steep foreign aid funding losses, African nations are accelerating efforts to boost manufacturing and laboratory capacity on the continent and reduce reliance on external partners. At October’s Conference on Public Health in Africa in Durban, South Africa, thousands of participants endorsed The Durban Promise, a roadmap for Africa’s health sovereignty, urging action on manufacturing, financing, workforce and capacity development, and regulatory strengthening, a signal of growing continental unity.This momentum was echoed by the Accra Reset, led by Ghanaian President John Mahama, to forge further progress toward greater sovereignty and more equitable global cooperation. At the continental level, the Africa Centres for Disease Control and Prevention launched a new biomanufacturing fellowship to help meet the goal of producing 60 percent of Africa’s vaccine dose needs locally by 2040.South Africa held the G20 presidency this year, culminating in the first G20 summit held on African soil and a declaration focused on priorities for Africa and the Global South. The summit was punctuated by the absence of the United States, underscoring the imperative for greater African autonomy as international aid declines and health threats rise. With the United States assuming the G20 presidency next year, its priorities will be closely watched. Looking ahead to 2026If 2025 has taught us anything, it’s that global health is unpredictable and constantly evolving, so we won’t speculate on exactly what 2026 may bring. But a truth remains clear: global health R&D is a strong investment that pays off—saving lives, strengthening economies, and fueling scientific progress. As the United States redefines its approach and role in the broader global health ecosystem, it remains to be seen how it, and others, will step up to ensure that promising technologies in the pipeline are advanced to improve lives around the world.For other fascinating global health news delivered to your inbox weekly and to stay abreast of developments in 2026 and beyond, sign up now to receive GHTC’s R&D News Roundup newsletter.

It’s been a difficult year for people worldwide who live with, are at risk of, or research HIV. Funding reductions and shifting priorities among key donors have disrupted or halted critical research and health services. Around the world, major international donors have reduced their funding for global HIV programming, leading to stoppages and cutbacks of lifesaving care. In the United States, new policies and grant terminations at the Department of Health and Human Services have significantly disrupted HIV research. The integration of the US Agency for International Development into the Department of State and resulting award terminations also interrupted HIV research and service delivery globally.These reductions risk undermining hard-won global progress and could lead to a resurgence in cases. Already, we’re seeing declines in HIV testing and treatment initiation this year. This is especially disheartening given exciting progress in recent years: at the end of 2024, new HIV infections were down 40 percent and AIDS-related deaths down 50 percent since 2010. The last few years have also brought exciting research advances, building momentum toward breakthroughs that could change the course of the global pandemic.With science yielding fruit and new donor countries and private funders stepping up, there is still hope that through renewed partnership and investment, we can regain momentum toward ending HIV/AIDS as a global public health threat. Here are some of the year’s most exciting advances in HIV research and innovation this year that inspire optimism amid significant challenges.A breakthrough in HIV prevention and accessIn June 2025, the US Food and Drug Administration approved lenacapavir as the first twice-yearly injectable drug for HIV prevention, marking a major milestone in the fight against the virus, While the drug, developed by Gilead using evidence from NIH-funded research, was previously approved for treating multidrug-resistant HIV, the new indication offers a discrete, twice-annual alternative to daily pills or bi-monthly injections, making prevention more accessible and easier to maintain. The approval followed highly successful clinical trials, which were notable not only for how effective the drug was across key populations, but also for their inclusion of historically underserved populations.Following the FDA’s decision, Gilead and the Global Fund to Fight AIDS, Tuberculosis and Malaria announced an access agreement that will see Gilead supply doses, at no profit, for up to two million people over three years. The Gates Foundation and Indian manufacturer Hetero Labs are also partnering to manufacture generic lenacapavir at an affordable price. The World Health Organization swiftly recommended the drug’s use, and South Africa’s regulatory authority approved it at record speed, the first such approval in Africa. It’s exciting to see partners work together to help ensure this breakthrough can be accessible in the communities where it is most needed quickly and affordably, a sharp divergence from past HIV product rollouts that saw years-long delays before people in low- and middle-income countries received access to new tools. Earlier this year, Gilead also published data suggesting a once-yearly version of the drug may be possible, with Phase 3 trials to begin later this year.Lenacapavir is not the only exciting advance in long-acting HIV prevention we saw in 2025. Merck’s investigational once-monthly oral prevention pill was found to be well tolerated in adults in a Phase 2 trial and is now undergoing Phase 3 trials in sub-Saharan Africa. Meanwhile, a single gene therapy injection given at birth showed promise in protecting primates from infection for at least three years in preclinical research. If this solution advances, it could be a gamechanger for preventing mother-to-child HIV transmission.Broadly neutralizing antibodies for long-term HIV control and cureBroadly neutralizing antibodies (bnAbs), which are made naturally by some individuals and target parts of the HIV virus that are less prone to mutation, are also showing promise in HIV treatment, prevention, and cure strategies. Studies have shown that bnAbs can effectively neutralize a broad range of HIV strains and bnAb combinations can maintain viral suppression in the absence of antiretroviral therapy, but challenges remain around their cost, global scalability, and the potential for viral resistance.Researchers are testing combination approaches with other drugs to potentially enhance the efficacy of bnAbs in controlling HIV. Study results presented earlier this year found that more than half of study participants living with HIV who received a pair of bnAbs plus the drug N-803 experienced delayed viral rebound or maintained a low or suppressed viral load during interruption from antiretroviral treatment. N-803, which is approved as a treatment for bladder cancer, appears to help reactivate and eliminate dormant HIV virus.Gilead also shared promising results from a Phase 2 trial earlier this year combining lenacapavir with two bnAbs as treatment for HIV. This regimen is the most advanced bnAbs-based treatment to date, with Phase 3 trials expected to start soon.Beyond treatment, many leading HIV scientists believe that a vaccine that elicits the production of bnAbs could be key to targeting the tricky, mutating virus. IAVI and partners developed immunogens, a type of antigen that can trigger an immune response, for use in a vaccine strategy to induce bnAb production, which demonstrated success in several Phase 1 clinical trials. A new study looking at data from two of the trials shows that this targeted vaccine strategy can successfully activate early immune responses relevant to HIV, an important step toward an HIV vaccine. The candidates use an mRNA vaccine platform, enabling faster production and clinical testing.While bnAbs have the potential to transform HIV prevention and treatment, further research is needed to overcome cost and delivery barriers to ensure that future innovations can be rapidly scaled up and distributed to the communities who can benefit most from them.While global HIV efforts have faced setbacks this year, we’ve also seen the extraordinary progress that’s possible when partners unite around innovation. New tools and approaches are emerging that could change the course of the global HIV/AIDS pandemic, preventing millions of new infections and deaths every year. But their impact depends on what happens next. To realize their full potential, countries, donors, and partners must come together and recommit to fund research, prioritize equitable access, and accelerate the scale-up of new tools. The future of the HIV/AIDS response hinges on how we meet this moment.

A Phase 1 randomized controlled trial found that a single dose of the ChAdox1 Rift Valley fever (RVF) vaccine was safe, tolerable, and elicited a strong immune response in 30 adults in Uganda, where RVF—a neglected, mosquito-borne disease that is considered a significant public health threat and a priority for vaccine development—is endemic. The trial was led by researchers at the Uganda Research Institute and the London School of Hygiene and Tropical Medicine Research Unit in Uganda and provides the first evidence supporting the vaccine from a trial in an endemic setting. While the vaccine could potentially be transformative for RVF prevention, further research is needed that follows participants for a longer period and includes a larger group of participants, including children, pregnant women, and immunocompromised people. Last week at the American Society of Tropical Medicine and Hygiene annual meeting, Medicines for Malaria Venture and Novartis shared the results of a Phase 3 study testing a new malaria treatment, known as GanLum, finding that the treatment was highly effective at treating malaria, including drug-resistant cases, and could also block disease transmission. GanLum was found to be 99.2 percent effective in curing patients, more effective than standard artemisinin-based combination therapies, the gold-standard malaria treatment introduced more than 20 years ago, whose use has been undermined since the emergence of partial resistance. The developers say that, pending regulatory approval, the new treatment could be rolled out within the next few years. South African pharmaceutical company Biovac is launching trials of a cholera vaccine, which, if it proves successful, could become the first vaccine developed from start to finish on the African continent. Africa faces the brunt of the global cholera burden but is almost entirely reliant on vaccines made internationally, which has become increasingly challenging in recent years as cases have risen sharply around the world and vaccine stocks have diminished. The African Union has committed to increasing the proportion of routine vaccines used in Africa that are manufactured on the continent from just 1 percent now to 60 percent over the next 15 years, an effort triggered by the access challenges African countries faced during the COVID-19 pandemic. 

The World Health Organization's (WHO's) TB Vaccine Accelerator Council recently published a new report calling for action to ensure equitable access to future tuberculosis (TB) vaccines currently in the pipeline. While the only licensed vaccine for TB is 100 years old and has limited effectiveness in adolescents and adults, as of September, there are 16 candidate vaccines in clinical development, six of which are in Phase 3 trials. WHO estimates that a vaccine for adolescents and adults that is at least 50 percent effective could avert up to 76 million TB cases and 8.5 million deaths over 25 years. However, as the report claims, global demand could far exceed supply in the initial years after a vaccine is approved because there is no designated funding for such a rollout in low- and middle-income countries most affected by TB, which are already facing significant funding shortfalls. In anticipation of these potential bottlenecks and barriers to access, the report identifies six solutions to encourage countries with a high burden of TB, manufacturers, and other funders and stakeholders to start preparing now for the rollout to ensure future vaccines can reach people who need them faster. In a Phase 1 randomized controlled trial, an experimental intranasal vaccine against multiple H5N1 avian flu strains generated a broad immune response, demonstrating the potential of such a vaccine to play a major role in preparing for outbreaks of emerging viruses with evolving strains, as H5N1 continues its worrying spread. The University of Maryland research team tested the vaccine against a placebo in 40 adults between 18 and 45, finding that the vaccine was safe, well-tolerated, and stimulated immunity at various doses. One group received a vaccine dose combined with an adjuvant, an ingredient used to trigger a stronger immune response, and their immune systems were better able to neutralize infected cells for longer, suggesting that the use of an adjuvant could be a promising approach that might allow for lower doses, which could stretch limited vaccine supplies in the event of an outbreak. Last week, IAVI published new findings from the first-in-human Phase 1 clinical trial of its Lassa virus vaccine candidate, which show that one dose of the vaccine triggers robust and long-lasting immunity and is safe. There are no vaccines or treatments currently licensed against the dangerous illness, which causes thousands of deaths in endemic West Africa and has been designated as a priority pathogen with pandemic potential. The trial enrolled 114 volunteers in Liberia and the United States. The candidate, now undergoing a Phase 2a trial in West Africa, is currently the most advanced Lassa fever vaccine candidate in the pipeline and uses the same platform as Merck’s single-dose Ebolavirus vaccine, which is approved in more than a dozen countries.
