The researchers found partial resistance to the drug in 11 of the 100 children treated in the study, with 10 patients “cured” of severe malaria having a resurgence of the same strain within a month of the original infection, implying that the first treatment did not fully eliminate the parasite. More studies are needed to determine how widespread artemisinin resistance is in Africa. Still, the findings underscore the need for novel or alternative drugs to be used in the treatment of severe malariaThe US Centers for Disease Control and Prevention (CDC) has awarded Alveo Technologies a contract to develop a molecular assay to detect and differentiate the H5 subtype of avian influenza A from seasonable influenza A and B viruses in humans, as the ongoing spread of H5N1 in animals across the United States raises concerns about a new pandemic as regular flu season looms. Currently, only CDC and US state and jurisdictional public health labs have access to CDC’s molecular test to detect the H5 strain of influenza A, which could lead to delays in diagnosis or treatment if we start to see transmission between humans. Decentralized testing capabilities at the point of care will be needed to ensure any spread between humans is detected and controlled quickly to avoid another pandemic, as well as to reduce the burden on centralized laboratories.  Last week, the endTB consortium announced the completion of the endTB-Q trial, the first Phase 3 randomized controlled trial to exclusively enroll people with pre-extensively drug-resistant tuberculosis (pre-XDR-TB), with preliminary results demonstrating that a shorter, less toxic treatment strategy of four drugs achieved high cure rates overall, especially in those with non-severe cases of TB disease. Pre-XDR-TB has historically been treated with toxic regimens that last up to two years, are hard to tolerate, and are not very effective. This study tested a personalized medicine strategy, with disease severity and early treatment response used to decide between a six- or nine-month treatment regimen. The study included participants from India, Kazakhstan, Lesotho, Pakistan, Peru, and Vietnam.

Nearly six months into fiscal year 2024 (FY24), the US government has finally agreed upon a budget for the remaining six months. Nevertheless, March brings with it a new appropriations cycle forcibly run in parallel with the last. With the release of the President’s Budget Request (PBR) for fiscal year 2025 (FY25) and ongoing meetings with appropriations staff, the prospects for future US spending on global health research and development (R&D) are coming into focus, with both good and bad on the horizon.FY24 spending package: A mixed bag for global health R&D This year’s appropriations process was certainly one for the history books in that it was historically difficult—largely due to partisan divisions and threats to the House speakership. But on March 22, moments before a partial government shutdown was set to go into effect, a six-bill “minibus” was voted through by the House of Representatives and the Senate and later signed into law, which will keep the government operational until September 30. This second spending package included funding bills for Labor, Health and Human Services, Education, and Related Agencies (LHHS); State, Foreign Operations, and Related Programs (SFOPS); and Defense, which are a mixed bag for funding for global health R&D.LHHSThe LHHS bill, which covers funding for the National Institutes of Health (NIH), the Centers for Disease Control and Prevention (CDC), and the Biomedical Advanced Research and Development Authority (BARDA), included some welcome increases to agencies and programs that support global health research alongside overall stagnant funding.Out of the three agencies, BARDA, which focuses on the R&D of countermeasures against emerging health threats, received the largest increase in funding with a $65 million (6.8 percent) boost over fiscal year 2023 (FY23) levels, bringing its total budget to $1.015 billion. The CDC, America’s lead public health agency, and NIH, the primary agency responsible for biomedical health research, witnessed marginal adjustments, with their budget lines most relevant to global health R&D remaining largely static. Notably, CDC's National Center for Emerging and Zoonotic Infectious Diseases (NCEZID) received a $9.5 million (1.27 percent) boost, which will help bolster crucial surveillance initiatives such as the Advanced Molecular Detection program.  Additionally, the minibus also included complimentary directives, known as report language, which were championed by GHTC, that reinforce the importance of global health and neglected disease research taking place at CDC and NIH. It also included important language encouraging BARDA to consider the needs of people living in low-resource settings in its R&D funding decisions and directing the agency to provide more transparent and regular reporting on its investments and allocate at least $10 million of its budget to create a new Disease X medical countermeasures program to develop tools against viral families with pandemic potential.SFOPSThe SFOPS bill covers global health work undertaken by the US Agency for International Development (USAID) and the US Department of State (State). Unfortunately, the FY24 spending package included a significant cut of $530.95 million (5.3 percent) to State and USAID global health programs.Much of this reduction is due to a decrease in funding by $350 million for the US contribution to The Global Fund to Fight AIDS, Tuberculosis and Malaria, which fell from $2 billion in FY23 to $1.65 billion in FY24. While this is a large cut, it was both expected and supported by advocates, given that US law caps the maximum contribution that the United States can make to the fund relative to the contributions of other donors. Thus, the “cut” was implemented in line with the cap to avoid a harsh drop-off in US funding in the coming years. Accordingly, many advocates are not viewing it as an actual cut. The remaining decrease in funding comes from a significant $200 million (22 percent) cut to USAID Global Health Security (GHS). The FY24 funding for GHS of $700 million retains a $100 million carve-out for a US contribution to the Coalition for Epidemic Preparedness Innovations, or CEPI, but advocates are still piecing together what the $200 million slash could mean for other GHS programming. This picture is further complicated by the opaque nature of how the US government intends to fund a contribution to the World Bank Pandemic Fund, which is neither specified in the bill in terms of a funding number nor in the programmatic budget line. The Biden Administration announced last year its intent to contribute $250 million to the fund, but this contribution is not actually detailed in the spending package, so it remains unclear how this commitment will be realized. Slightly cushioning the overall cut to State and USAID global health programs are some modest increases to the budget lines for the maternal and child health (through an increase in funding to GAVI, the Vaccine Alliance), nutrition, and other public health threats programs.In a key win for global health research advocates, Congress also included accompanying report language for SFOPS directing USAID to increase its spending for health R&D over the prior fiscal year and to publish an annual report on its health R&D activities and investments. Notably, the reauthorization of the US President’s Emergency Plan for AIDS Relief, or PEPFAR, was also included in the SFOPS bill but only for one year, so authorization will expire next March. This one-year reauthorization tees up another battle, which will certainly be shaped by the political climate and controlling parties following the presidential and congressional elections this fall.DefenseWhile few may think of the US Department of Defense (DoD) as a key global health player, the agency’s spending supports R&D against epidemic-prone diseases and other health issues that pose a risk to US national security and service members stationed abroad—so its investments contribute to combating diseases endemic in many of the world’s poorest places. Encouragingly, language supporting DoD's research on infectious diseases and the development of medical countermeasures was included in the accompanying Defense bill report.Unfortunately, however, Congress did not include tuberculosis among the diseases eligible to be funded via the DoD-led Congressionally Directed Medical Research Program’s (CDMRP’s) Peer Reviewed Medical Research Program (PRMRP), as has been the case in years past. This is a point of future advocacy since the CDMRP PRMRP funds other neglected and emerging diseases in line with the list of eligible diseases defined in the Senate’s Defense bill each year.FY25 President’s Budget: A story of lowered ambitionOn March 11, President Joe Biden released his FY25 budget request, outlining his administration's recommendations to Congress for spending for the next fiscal year. The FY25 PBR is more moderate than Biden’s FY24 proposal, which can be largely attributed to the administration upholding their end of the debt ceiling bargain to keep overall spending levels capped at roughly FY23 levels. But even still, the lack of boldness for global health activities across the board was felt by advocates.With respect to global health programs at State and USAID, the budget proposes an overall decrease of approximately $733 million (7 percent) compared to FY23 enacted levels. This includes a $175 million (4.2 percent) cut to USAID and a $558 million (8.9 percent) cut to State global health programs. Concerning the latter, the cut comes from the PBR proposing a $1.19 billion contribution to the Global Fund, which would be an $810 million reduction from FY23 levels. As previously noted, this drastic cut is due in large part to the cap imposed on maximum US contributions; however, advocates are still pushing for $1.65 billion in FY25, citing projections that the US contribution can be set higher without violating the cap. The proposed USAID cut is more nuanced and comes from an accounting choice by the administration to transfer funding for the US contribution to the Pandemic Fund ($250 million) from under the Global Health Security line at USAID to the budget for State’s new Bureau of Global Health Security and Diplomacy, which will now manage US engagement with the fund. In conversations with the agency, the movement of this funding is not being perceived as a cut—leaving USAID’s global health programs largely untouched in the PBR. Most programs are flat funded, though the budget proposes a modest $30 million (3.3 percent) boost to USAID’s maternal and child health programs and a reduction of $26 million (4.5 percent) to USAID’s family planning account.On the LHHS side, the budget proposal is slightly rosier, though far from ambitious. The PBR proposes increases of $20 million (2.1 percent) for BARDA and $1.4 billion (2.3 percent) for NIH overall, with the latter including a modest boost of $18.72 million (0.3 percent) for NIH’s National Institute of Allergy and Infectious Diseases but flat funding for NIH’s Fogarty International Center, which supports global health research and training. CDC received a proposed increase of $465.4 million (5 percent) in the PBR, with NCEZID receiving a $30 million (4 percent) increase and the Center for Global Health flat funded.Notably, CDC’s congressional budget justification proposes that $20 million of this funding for NCEZID be put towards wastewater surveillance, which is programming that is currently being supported unsustainably via emergency funding for the COVID-19 response. Additionally, in the BARDA congressional budget justification, the administration suggests a $20 million boost “to increase BARDA’s Broad Spectrum Antimicrobials and Combatting Antibiotic-Resistant Bacteria portfolio" through engagement with the Combating Antibiotic-Resistant Bacteria Biopharmaceutical Accelerator, or CARB-X, an international partnership focused on accelerating the development of new antibacterial innovations.While GHTC understands the administration’s fiscal situation and negotiating position with Congress, the discrepancy between the administration’s ambitions from the FY24 PBR to the FY25 PBR are stark, with some agencies seeing decreases of over $1 billion between the two presidential requests.FY25 outlook: Not great, but not badWhile it may feel cruel for advocates, there is no breathing room between the FY24 and FY25 appropriations processes. Additionally, the constraints the global health community felt in 2024 in the wake of the Fiscal Responsibility Act of 2023—also known as the Biden-McCarthy Debt Ceiling Deal that capped spending growth—are still with us. Even though the outcomes of the FY24 spending package were discouraging for global health advocates—it went better than many expected. For FY25, while a robust and bold global and public health budget is the goal—holding off any cuts and returning to FY23 topline budgets for global health programs will be critical. GHTC will be working to communicate that message clearly while keeping in mind the uphill battle caused by the parameters forced upon appropriators by last June’s debt ceiling deal.Other obstacles like election-year politicking and a remarkable loss in global health champions in Congress will make future negotiations harder and will require advocates to go more on the offense. Pushing for stronger toplines and no cuts will be vital in FY25 to get the gains the community needs to get the world back on track toward eradicating neglected diseases and better preparing for emerging threats.

The funding will specifically support the development of the vaccine candidate GPV02, which offers protection to newborns through the antibodies passed on by vaccinated expectant mothers in utero and through breast milk after birth. GPV02 uses a unique approach compared to other attempted protein-based bacterial vaccines because it involves previously undiscovered natural sugar modifications and uses BEMAP technology to allow the vaccine to imitate E. coli, preparing the immune system to recognize the bacterium in the case of future infection.Last week, the Advisory Group on Immunization Practices at the US Centers for Disease Control and Prevention (CDC) recommended Valneva’s Ixchiq chikungunya vaccine for some travelers and laboratory researchers at risk of contracting the mosquito-borne virus. The United States records about 100 to 200 chikungunya cases a year in people infected abroad by the virus, which is mainly found in parts of Central and South America, Africa, and Asia. The vaccine was licensed by the Food and Drug Administration last fall for adults—the first vaccine approved for chikungunya. CDC has indicated that it may later expand the recommendation for people living in US territories where the virus may spread.A new extensive, long-term analysis from the Icahn School of Medicine at Mount Sinai found that COVID-19 vaccines induce long-lasting antibody responses, debunking previous claims that mRNA-based vaccine immunity wanes quickly. The researchers examined in over 8,000 samples collected over three years in New York City how antibody responses changed after infections, during the first series of vaccinations, during booster vaccinations, and during breakthrough infections. They concluded that the major reason for breakthrough infections is the virus evolving to evade immunity rather than waning immunity. The results will, hopefully, not only encourage people to continue to get vaccine boosters but also to continue research into new vaccines and viral variants.

The panel runs on a BD system widely used by hospitals and labs across the United States that can process hundreds of samples a day and deliver results in two hours. By reducing the need for multiple tests to distinguish the cause of respiratory infections, the test will help patients receive appropriate care faster and reduce burdens on the health system, which is important as the United States faces the rising threat of these viruses over the coming months.FDA is expected shortly to approve updated versions of the COVID-19 boosters, which although originally designed to target the XBB.1.5. omicron subvariant should still protect against the currently circulating subvariants, as cases and hospitalizations linked to the new variants rise. While it remains unclear whether the agency will grant emergency use authorizations or full approval licenses, either will trigger the Centers for Disease Control and Prevention to make its recommendations for who should receive the shots, allowing vaccinations to likely begin soon in the United States.Ghana recently became the first country in Africa to manufacture a cholera vaccine. The private-sector pharmaceutical consortium DEK Vaccines Limited produced the vaccine, as well as six others, including against malaria, HPV, pneumonia, and rotavirus, which are expected to be available by 2026. This was made possible through a licensing and technology transfer agreement with the International Vaccine Institute (IVI). Scaling up local production of vaccines is seen as an important step toward enabling Ghana, the West African region, and the continent at large to reduce the critical shortage of vaccines and reliance on foreign countries and companies and to ensure greater access to vaccines that protect against endemic diseases.
