Nitisinone, which is currently used to treat a rare genetic condition in humans, kills mosquitoes by blocking an enzyme that is necessary for them to process human blood, which is not a pathway targeted by any currently used insecticides. The research suggests that the drug could be formulated for use in indoor residual spraying or insecticide-treated bed nets, helping eliminate mosquitoes even in settings where rising insecticide resistance has undermined the effectiveness of current vector control methods.Early last week, the Gates Foundation announced a $2.5 billion commitment through 2030 to accelerate research and development on women’s health. Specifically, the funding will help advance more than 40 innovations in five critical areas: obstetric care and maternal immunization, maternal health and nutrition, gynecological and menstrual health, contraceptive innovation, and sexually transmitted infections. These areas were selected based on extensive data about where innovation can save and improve the most lives and where there are persistently high rates of misdiagnosis, as well as direct insights from women in low- and middle-income countries about their needs, preferences, and challenges.Last week, IAVI; the Mutala Trust; ReiThera; and the Ragon Institute of Mass General Brigham, the Massachusetts Institute of Technology, and Harvard University announced that the first doses of an investigational HIV vaccine candidate were administered in their Phase 1, first-in-human clinical trial. The clinical trial is taking place at three sites in Zimbabwe and South Africa among 120 healthy adults, including people living with HIV. Carrying out the trial in sub-Saharan Africa, which faces the highest disease burden, will help ensure the vaccine is effective and relevant in the communities where it is most needed. The vaccine candidate is designed to stimulate the immune system, particularly CD8+ T cells, to recognize and target critical structural regions of the virus. Scientists believe CD8+ T cells could potentially target HIV-infected cells, so the trial will also assess whether the vaccine candidate could be part of future therapeutic or cure technologies.

The repository, which will be housed at the United Kingdom’s Medicines and Healthcare products Regulatory Agency and funded and led by the Coalition for Epidemic Preparedness Innovations, will include 25 adjuvants available for use in developing new vaccines against epidemic and pandemic threats. The library will act as a matchmaking service, helping developers select the best suited adjuvants to increase the effectiveness and potency of their vaccines. The project is intended to support the 100 Days Mission, an ambitious global effort to develop vaccines against newly emerging threats in as few as 100 days.A new study has found that delivering a single gene therapy injection at birth could offer years-long protection against HIV. In the study, non-human primates who received the therapy within their first month of life saw protection for at least three years without the need for a booster—a potential signal that protection could last into adolescence in humans—, while those treated at 8-12 weeks saw a less effective immune response. The immune system is naturally more tolerant within a person’s first weeks of life, so it marks an optimal window for gene treatment that could be rejected at an older age. While questions remain as to whether these findings will translate to human infants and children, if successful, this treatment could offer a “one-and-done” multiyear solution to protect again mother-to-child HIV transmission that could be more cost-effective and feasible to implement in low-resource settings worldwide.The antiparasitic drug ivermectin was found to reduce the incidence of malaria by 26 percent in a trial conducted in Kenya, a finding that demonstrates its potential use for mass drug administration alongside other malaria control interventions. Invermectin is a drug commonly used to treat parasitic diseases like onchocerciasis and lymphatic filariasis, but scientists have been exploring its potential in malaria prevention, given the rise in insecticide resistance, which has rendered other prevention tools like insecticide-treated bednets and indoor residual spraying less effective. The trial, which involved more than 20,000 participants, compared the drug, administered in a single monthly dose for three months during the rainy season, with the antiparasitic albendazole—both alongside use of existing bed nets. It is the largest study of ivermectin for malaria conducted to date.

On Thursday, Senate appropriators advanced out of committee a fiscal year (FY) 2026 spending bill for the Department of Health and Human Services (HHS) that rejects billions in health spending cuts proposed by the Trump Administration and protects programs vital to global health innovation.The bill increases or flat-funds global health research-relevant agencies, including the National Institutes of Health (NIH) and Biomedical Advanced Research and Development Authority (BARDA), and slightly reduces funding for the US Centers for Disease Control and Prevention (CDC) compared to FY25 enacted—an outcome that is in stark contrast to the President’s Budget Request (PBR), which proposed deep cuts across all three. Funding at this level will enable these agencies to continue to advance medical breakthroughs and operate programs that deliver better health outcomes for people around the world and fortify our defenses against disease threats.Funding highlightsThe legislation allocates $48.7 billion in funding for NIH, which is a $400 million (.8 percent) increase compared to FY25 enacted and nearly $22.2 billion (77 percent) above the PBR, and $1.015 billion for BARDA, which represents level funding from FY25 but $361 million (55 percent) more than the White House request. While the legislation unfortunately cuts funding for CDC by $72 million, or 1 percent, this allocation is $4.8 billion or 112 percent greater than the President’s request.While advocates expected the Senate to reject the steep cuts proposed by the Trump Administration, many still anticipated significant reductions. It is therefore both welcome and surprising that Senate appropriators advanced a spending package that maintains strong funding for many programs the President aimed to slash or eliminate.Beyond topline funding for agencies, the bill and accompanying report also diverge from the PBR in other crucial ways. While the President proposed eliminating the CDC Global Health Center (GHC), this spending bill keeps the center intact, maintaining level funding from FY25. The bill also maintains flat funding for the NIH Fogarty International Center—which supports global health research partnerships and training—and provides a 0.5 percent increase to the NIH’s National Institute of Allergy and Infectious Diseases (NIAID). This stands in sharp contrast to the White House’s proposal to eliminate Fogarty entirely and cut NIAID’s budget by 58 percent. Additionally, it provides level funding to the Advanced Research Projects Agency for Health (ARPA-H), a new agency established under the Biden Administration to support high-risk, high-potential health research, rejecting the President’s proposal to reduce its funding by $555 million.Beyond  funding numbers, the bill’s accompanying report includes welcome directives affirming the Senate’s support for research activities critical to global health, including across health areas like neglected tropical diseases, malaria, tuberculosis, emerging infectious diseases, antimicrobial resistance (AMR), and more, and underscores the importance of international health research partnerships and training programs supported by the Fogarty International Center and global health activities undertaken by CDC GHC and NCEZID.  Taken together, the funding and directives can be viewed as a strong rebuke of the president’s efforts to downsize and dismantle US global health efforts and a strong affirmation of the Senate’s support for programs that save and improve lives around the world and protect Americans from disease threats. The report also dictates stricter reporting requirements to Congress for HHS, indicating bipartisan concern by lawmakers as to whether the agency is dispersing funding as directed and making scientifically-drive decisions.The report also conveys Senate appropriators’ desire to see BARDA devote robust funding to developing countermeasures against emerging infectious diseases, AMR, and pandemic influenza, and directs BARDA to spend no less than $10 million on advancing countermeasures against “Disease X,” which is a term to denote priority viral pathogens that could cause the next pandemic. Despite an overall positive picture, the bill does include some decreases to subaccounts relevant to global health, including an 80 percent cut to  the CDC-wide Infectious Disease Rapid Response Fund, which was a fund originally created to provide flexible funds for the agency to rapidly respond to pandemic and epidemic threats. See the chart below for a more detailed comparison of funding in the Senate bill and percent changes compared to FY25 enacted and the PBR.What comes nextThe bill’s passage out of committee is just an initial step in a lengthy political process. It will next go to the full Senate for a vote, the House of Representatives will need to advance its parallel bill, and then the two bills will need to be conferenced to work out their differences before going back to both chambers for a vote and then to the President for signature.It is anticipated that the House will propose lower spending levels for health programs than the Senate, so these numbers are a likely high watermark where negotiations begin between the two chambers. Nonetheless, if one reads the House’s spending bill on global health as a tea leaf of what’s to come, it’s unlikely the House will cut as deep as the President wishes , so if the two chambers can reach a compromise and pass a budget, we could see funding levels land somewhere below the Senate but still substantially above the PBR. In the House bill, we are likely to see stronger relative numbers for NIH over CDC, given heightened criticism for the latter agency among Republican lawmakers.For many advocates, this bill is welcome news that Congress is reasserting its power of the purse in opposition to the president, yet significant concerns remain. Will the two chambers actually reach a promising compromise? And even if Congress appropriates strong funding for FY26, given all the recent moves by the Administration to rescind, halt, or slow the disbursement of federal spending, will this money actually reach researchers and health implementers to deliver impact? While we can’t predict for certain, GHTC and other advocates will continue to keep a close watch on what’s to come and activate where we can in order to protect vital funding for global health and medical research.

The drug candidate, AN2-502998, is currently being tested in a Phase 1 first-in-human clinical study, scheduled for later in 2025, with a Phase 2 proof-of-concept study expected to commence next year. The partnership will leverage DNDi’s established network of clinical trial sites throughout Latin America and Spain, established through its previous Chagas clinical trial work.A team of researchers shared last week that they have developed a special kind of floss that could serve as a vaccine delivery method, delivering proteins and inactive viruses to the gums and triggering immune responses that can protect against infectious disease. While scientists have long been investigating alternatives to syringes like oral and nasal vaccine delivery methods, a challenge they’ve come across is that the mouth and nose have naturally tough defenses against foreign molecules. The flossing approach overcomes this challenge by targeting the pockets of gum between the teeth that are better at absorbing molecules. The approach proved successful in mice in multiple tests where researchers coated the floss in protein and inactive flu virus, and researchers have also tested the feasibility in humans, finding positive results. Further research will help determine if the technique will work in humans with a wide variation in gum health, including people with gum disease.Study results presented at the recent International AIDS Society Conference in HIV Science found that more than half of people living with HIV who received a pair of broadly neutralizing antibodies plus the drug N-803 experienced delayed viral rebound or maintained a low or suppressed viral load during interruption from antiretroviral treatment. While antiretroviral treatment can keep HIV suppressed indefinitely, the long-lasting viral reservoir maintained in the body has confounded researchers efforts to eliminate it, putting a cure out of reach. A small proportion of individuals naturally make unique broadly neutralizing antibodies that target key parts of the virus, which researchers have been trying to replicate with a manufactured drug. N-803, which is approved as a treatment for bladder cancer and is being studied in both cancer and HIV research, appears to be able to both reactivate dormant HIV and clear the virus out of hiding. Further research and an analysis across studies testing the approach will help confirm the underlying mechanisms of the effects researchers are seeing and determine whether the drug could be part of a future cure.
