The researchers vaccinated mice with LC16m8 to see how it protected them from mpox, later vaccinating monkeys and healthy adult volunteers as well to study their blood samples for immune responses and monitor them for safety. The results underscore LC16m8’s potential as a safe, effective, and scalable choice for mpox vaccination and also provide a blueprint for developing next-generation vaccines against other poxviruses and emerging pathogens.Researchers from Abertay University and Bangor University have developed a prototype blood test that can detect up to five infections at the point of care, providing results quickly via a smartphone app. The tool, which was piloted using tuberculosis as a test case, showed high sensitivity and an ability to accurately identify cases. The speed and convenience, as well as the much lower cost compared to lab testing, demonstrate the test’s potential to be a game changer in ensuring access to timely testing and diagnosis, particularly in remote locations and other settings lacking laboratory infrastructure.  The results of a Phase 3 clinical trial published last week found that Moderna’s combination COVID and flu shot outperformed existing individual vaccines for both viruses. The combination shot uses the same mRNA technology as Moderna’s approved vaccine for COVID-19, but there are no currently approved mRNA flu vaccines. In a trial that included more than 8,000 adults, the combination vaccines generated higher antibody levels for COVID and all but one influenza strain in trial participants who got the combination vaccine compared to those who got individual vaccines. A combination vaccine could help boost vaccination levels for both viruses, and an mRNA vaccine, in particular, could also speed up production because they are faster to make than current flu shots.

For the first time, global leaders have come together to lay out a comprehensive plan for pandemic prevention, preparedness, and response. After over three years and 13 formal rounds of negotiations, member states of the World Health Organization (WHO) defied expectations and reached consensus on a Pandemic Agreement. The final draft of this legally binding instrument will lay the groundwork for stronger global cooperation and be a major catalyst for a more robust research ecosystem that ensures that the fruits of innovation are more equitably shared.  A win for multilateralism! This agreement is a major win for multilateralism. At times, there were reasons to think the negotiations might fail, including seemingly intractable disagreements between high-income and low- and middle-income countries on access and intellectual property issues. Then came the announcement in January that the United States intended to withdraw from WHO and would take no further part in the treaty talks. International cooperation has been tested, and it was important for the global health community to clear this hurdle.  While the text agreed upon in Geneva reflects compromise and not all negotiators’ ambitions were met, it represents important progress and lays the groundwork for action toward global readiness and equity in future health emergencies.  What’s in it for R&D? Efforts to accelerate the research and development (R&D) of vaccines, drugs, and other medical countermeasures were at the heart of the negotiations, and member states agreed to the following priorities: Promote technology transfer—which involves the transfer of scientific knowledge and know-how from one party to another to facilitate the broader production and availability of products—under “mutually agreed” terms. While this qualifier was disappointing to some low-income countries who had hoped for stronger commitments to help scale up local manufacturing of lifesaving medical countermeasures, it was ultimately a red line for wealthier countries, which prioritized preserving existing intellectual property frameworks.  In a historic first, the text obligates countries to attach conditions for access to publicly funded R&D contracts, a landmark step toward promoting equity. If implemented effectively, this means countries would be empowered to use contract enforcement measures to ensure public R&D spending ultimately results in products that reach patients. An agreement to promote post-clinical trial access to products for trial populations and for populations at risk in their communities, as well as commitments to support the transparent publication of clinical trials protocols and research results.  A framework for a new Pathogen Access and Benefits Sharing (PABS) system that grants companies access to scientific data, such as pathogen samples and genomic sequences, in return for more equitable sharing of drugs, vaccines, and diagnostics during a pandemic. Countries agreed that 20 percent of the vaccines, drugs, and diagnostics produced by participating manufacturers will be made available to the WHO for distribution. PABS wasn’t finalized during the negotiations and will now have to be fully developed through a new working group and added as a separate annex to the agreement. Establishment of a Global Supply Chain and Logistics Network to coordinate resource allocation, reduce access barriers, and mitigate the practice of hoarding of pandemic products through shared stockpiles. Beyond R&D, other key elements of the proposed agreement include a commitment to a “One Health” approach to pandemic prevention, efforts to strengthen national health systems, and the creation of a coordinating financial mechanism to support implementation of new obligations and capacity-strengthening measures.For a more detailed breakdown of the agreement, check out this briefer!Next steps: World Health Assembly and beyond After three years of intense negotiations and significant progress made toward aligning key provisions, critical procedural steps remain before the agreement can be formally adopted and implemented.   First, the text must be adopted by member states at the World Health Assembly later this month. There will then be an intergovernmental working group that will convene to hash out the details of the PABS system, likely over the course of the next year. Once the PABS annex has been finalized, at least 60 countries must ratify the treaty—in accordance with their own national laws and processes—in order for the Pandemic Agreement to become international law and enter into force. Finally, in order to support implementation and ensure enforcement and accountability, a “conference of parties” will be established to regularly review the agreement’s implementation.  The agreement has now reached an important milestone, but the work is not done. Leaders must carry it across the finish line later this month before committing to the task of ensuring its success through robust implementation.

The new study fills a gap in knowledge of the safety and efficacy of this approach for young children, who face the highest burden of clinical malaria and are particularly at risk of artemisinin-resistant strains but could face adverse complications from adult formulations of primaquine. The findings highlight the need for child-friendly formulations of primaquine and support the expanded use of the drug in regions with a moderate-to-high transmission rate and the threat of artemisinin partial resistance.The Drugs for Neglected Diseases initiative, the National Health Service University Hospitals of Liverpool Group, and the University of Liverpool have initiated a clinical trial in Liverpool, United Kingdom to test an oral drug for visceral leishmaniasis, one of the world’s deadliest parasitic diseases. Current treatments for visceral leishmaniasis, which is almost always fatal if left untreated, include daily injections for up to 17 days, which can cause immediate pain, as well as nausea, vomiting, and more serious complications. The new oral drug, DNDI-6899, is easier to store, transport, and administer than current treatments. If proven successful, the drug could help make treatment more accessible to those who need it most.DioSynVax and ACM BioLabs have signed a new deal to jointly develop a next-generation avian flu vaccine with the potential for mucosal vaccine delivery, as the virus continues its worrying spread. The mRNA vaccine targets all major clades of the H5 avian flu subtype and could be scaled for rapid distribution globally in the case of a pandemic. The vaccine is also designed to be delivered via nasal spray, which could help increase uptake; to induce mucosal immunity, which helps fight the pathogen before it starts circulating the body; and to be temperature stable, enabling rollout in lower-resource settings.

This trial builds on previous Phase 2 testing in Kenya and Uganda, as well as an open-label Phase 2 trial in Rwanda during the country’s outbreak last year. These trials in the African regions where Marburg and other similar viruses are most common or endemic are key to ensuring the vaccine is effective in the populations currently facing the highest risk of outbreaks. In addition, this new trial in the United States provides key safety and immune response data in non-endemic populations, helping prepare us for the possibility of outbreaks outside of the virus's typical range.Researchers have discovered a small antibody fragment that can block fertilization by targeting a key protein on the egg's surface, potentially paving the way for a nonhormonal contraceptive method. The fragment was found to be effective in mice, and it could potentially have fewer side effects due to its small size. Currently available hormonal contraceptive methods can cause side effects, like mood changes, headaches, or increased risk of blood clots, leading researchers to look for nonhormonal options for people who do not want to or cannot use hormonal methods. The researchers will next develop a similar antibody for human targets and test it in IVF experiments.The Drugs for Neglected Diseases initiative (DNDi) and partners initiated Phase 2 clinical trials in Malawi and Tanzania testing a new, easier-to-administer, and patient-friendly formulation of flucytosine, a medicine used to treat cryptococcal meningitis, which is a major health threat to people with weakened immune systems, including those with advanced HIV disease. Currently, flucytosine can be difficult to administer in resource-limited settings, and many countries face limited supply. As a result, access to timely treatment is limited in Africa, where the disease kills up to 70 percent of those who get it. The new formulation reduces dosing frequency from four times a day to just twice daily, is easier to take with water or through a nasogastric tube, and is suitable for outpatient self-administration.
