The momentum behind developing an HIV vaccine has increased in recent years, but sudden cuts to research and increased political scrutiny have threatened progress. “That’s a perfect storm to prevent us from building on the most exciting science HIV vaccines have had in 45 years,” AVAC’s Executive Director Mitchell Warren tells Vox.
An HIV vaccine is within reach
In ongoing trials, twice-yearly HIV prevention drug saw just one case
As lenacapavir is rolled out in 10 African countries, new findings indicate that the twice-yearly injection is highly effective for people who adhere to it. Also important: It is extremely popular. “Not only is this data reassuring for safety and efficacy, but it is a loud signal that the field needs to move with even greater speed, scale and equity in translating these results into public health impact,” AVAC Executive Director Mitchell Warren tells Devex.
HIV Cure Research Cohorts
HIV cure research depends on cohorts of people living with HIV who volunteer to participate in studies over many years. These cohorts help researchers understand how HIV persists in the body, identify factors that may influence the success of cure strategies and evaluate promising interventions. This infographic highlights major HIV cure research cohorts around the world, demonstrating the global collaboration and long-term investment required to advance HIV cure science.
Source of Lenacapavir for PrEP Supply to Early Adopter Countries
The Global Fund, with support from CIFF, and PEPFAR have jointly committed to reaching up to two million people with injectable lenacapavir for PrEP over three years. Supply of LEN began arriving in countries in late 2025 with service delivery starting in early 2026.
The Future of the HIV Response: Sustaining Progress in an era of Political Uncertainty and Scientific Opportunity
Significant progress has been made in expanding access to HIV treatment and prevention, but major gaps in coverage and equity were further exacerbated and destabilized by changes in US government support in January 2025. This commentary by AVAC’s Executive Director Mitchell Warren examines the implications of this divergence and argues that the future of the HIV response depends less on new biomedical discoveries than on the capacity to deliver existing and emerging options sustainably and with speed, scale and equity.

Global Health Watch: Latest on White House OMB Federal Rx Grant Proposal, Global Fund Gains Stability, New Model for GH Partnerships
As the comment period to oppose the White House Office of Management and Budget’s (OMB) proposal to give political appointees greater authority over federal research grants closes next Monday, the Global Fund avoided new ideological restrictions on US funding even as it prepares for a new Executive Director. And new articles and analyses of US bilateral health agreements under the “America First Global Health Strategy” suggest the Administration’s vision for global health is shifting from supporting epidemic control to managing country transitions.
The Latest on the White House OMB’s Proposal Politicizing Federal Grants
The last day to submit comments opposing the OMB’s proposal to give political appointees greater authority over federal research grant decisions is Monday, July 13. The proposal has drawn major and widespread opposition from scientists, advocates, universities, associations, former government officials, the biotechnology industry and members of Congress, all calling out the weakening of a long-standing scientific peer-review process and injection of political considerations into federal funding. The proposal has already drawn more than 93,000 public comments and submissions opposing the rule. See AVAC’s submission. The US Administration aims to finalize the rule by October 1.
IMPLICATIONS: These rules, if adopted, would mandate that federally-funded science align with a politically motivated “America First” agenda aimed at dismantling decades of transformative global collaboration. These rules have the potential to dramatically reshape how federal dollars are spent and who decides, replacing evidence-based decision-making with political priorities. Notably, the published proposed rule specifically and falsely references PEPFAR as justification for increased political scrutiny of federal grants, linking HIV and global health programs to a broader debate over federal spending, oversight and executive authority. For the HIV field, these changes could affect the entire research-to-rollout continuum and global partnerships, at a time when scientific collaboration is necessary to achieving 2030 HIV targets and advancing global health equity.
TAKE ACTION: The proposed rule is still open for public comment through July 13. Click here to comment or see AVAC’s Action Alert for more instructions. Submitted comments could slow implementation of any changes to the process because the OMB must reply to them all. The outpouring of comments could also persuade Congress, which has repeatedly rejected the Administration’s previous proposals to gut research funding, to use its power to stop these changes. Comments also put into the public record that are not adequately addressed, could be raised again in lawsuits to stop the changes.

Global Fund Gains Stability Amid Leadership Transition
The US government will continue funding the Global Fund without imposing its expanded global gag rule or other ideological funding conditions to US contributions. This will allow US funding to continue without restrictions related to abortion, diversity, equity and inclusion policies. At its Board meeting this week, the Global Fund also confirmed that its search for a new Executive Director will proceed as planned despite reports that the confidential nomination process might be restarted following media leaks. The Board is expected to appoint its next Executive Director in October.
IMPLICATIONS: While the decision not to impose the expanded global gag rule removes one immediate challenge, the Fund still faces significant financial uncertainty. Its next Executive Director will inherit an organization facing the major challenges of constrained resources, evolving donor expectations and increasing pressure to sustain impact in a changing global health landscape.

The New Model for US Global Health Partnerships
PEPFAR and US bilateral health agreements continue to evolve. This week, Think Global Health expanded its tracker of the US Administration’s bilateral health agreements, showing that 31 countries have now signed five-year agreements that increasingly shift financing and implementation responsibilities to national governments through co-investment and country ownership models. Andrew Green focuses on one country, South Sudan, in a Devex piece that looks at the country’s new three-year, $166 million MoU with the US, noting that while it preserves support for HIV and disease surveillance, funding may be insufficient to offset recent aid reductions and the country may struggle to meet its own financial commitments.
In a separate analysis, Jirair Ratevosian broke down what five reports from the US Department of State to Congress reveal about the Administration’s vision for global health. He writes, “Read together, these excerpts are overwhelmingly about the mechanics of transition: MOUs, implementation plans, co-investment, funding adjustments, corrective actions, benchmarks, workforce transfer, and reductions in US assistance. There is much less discussion of incidence, viral suppression, advanced disease management, prevention gaps, community systems, or epidemic control… It suggests they are no longer the organizing principle.”
IMPLICATIONS: These pieces reflect a move toward implementation of the new global health agreements. As implementation continues, we’ll be watching whether the financing assumptions, implementation systems and country commitments that are the foundation of these agreements are sufficient enough to sustain HIV and broader health gains. As Ratevosian notes, “Every Administration has its own priorities. But organizing principles matter because they determine what leaders measure, what they reward, and ultimately what they protect. When transition becomes the primary frame, there is a risk that epidemic control becomes something assumed rather than something actively managed.”
