The trial found that mRNA-1083 was similarly effective to two already approved flu vaccines developed by GSK and Sanofi and Moderna’s own SpikeVax COVID-19 vaccine. There were also no new safety concerns reported with the combination vaccine compared to each of the vaccines used alone. A phase 3 trial testing the combination shot will begin before the end of the year with potential regulatory approval in 2025 if successful. The company also laid out its broader efforts on combination vaccines, including a combination shot for COVID-19, flu, and respiratory syncytial virus.The Biomedical Advanced Research and Development Authority (BARDA) has awarded Vir Biotechnology $50 million in Project NextGen funds to advance the development of novel monoclonal antibody (mAb) candidates and delivery solutions for COVID-19 and future pandemic threats.  The new funding will support development of alternative mAb delivery technologies that increase antibody expression relative to existing solutions, which could revolutionize mAb delivery by expanding administration options and shortening development and manufacturing timelines. Four-fifth of the funding will specifically go toward advancing Vir’s next-generation COVID-19 mAb, Vir-7229, through a phase 1 trial, expected to be completed in late 2025, while the remainder will support the discovery of new mAbs against a second pathogen of pandemic potential.The World Health Organization (WHO) last week recommended the R21/Matrix-M malaria vaccine, developed by the University of Oxford. This follows two years after WHO recommended RTS,S, the first malaria vaccine. Both vaccines have a similar efficacy profile and delivery method and are targeted to children, but doses of R21 are expected to be cheaper—between $2.00 and $4.00 compared to about $7.25 now charged for RTS,S. The Serum Institute, which will produce R21, has also announced plans to deliver a much higher volume of doses compared to GSK’s current marketing plans for RTS,S. Although it will take more time to collect further safety monitoring data for R21, the recommendation of a second vaccine will hopefully help to ensure adequate supply for malaria-endemic countries that are planning to integrate a vaccine into their national malaria control plans.

With thousands of delegates dashing from one meeting to another in the frenetic New York streets, it was clear that the United Nations General Assembly (UNGA) was back in full swing this year. Given the three High-Level Meetings (HLMs) on global health, including pandemic preparedness, prevention, and response (PPPR); universal health coverage (UHC); and tuberculosis (TB), this was already set to be a major opportunity to reset coming out of the worst of the COVID-19 pandemic. Yet despite high ambitions, this year’s forum fell short of expectations, with many key issues, such as new agreements for sharing medical countermeasures (MCMs), accountability and enforcement mechanisms, or new funding commitments, being either punted to other forums or ignored. Innovation did feature strongly in all three HLMs, and despite the general disappointment, the research community was able to notch a few wins.A milestone in global pandemic preparednessThe UNGA HLM on PPPR marked a historic moment with the adoption of a political declaration. While nonbinding, this declaration carries significant symbolic weight, underscoring the global recognition that pandemic threats transcend mere health emergencies; they are existential threats that must be addressed with a whole-of-society approach. However, it was clear in the lead-up that the ambition had been severely curtailed and much of the text of the political declaration watered down. The meeting saw minimal participation from heads of state and inadequate representation from civil society. Many countries chose to focus on their past accomplishments in PPPR without articulating clear next steps or new commitments.Funding (or lack thereof) was another key theme of the week. The declaration emphasizes the importance of supporting sustainable and alternative financing mechanisms, as well as strengthening the capacity for innovation and production of MCMs. Specifically, it highlights the need to assist low- and middle-income countries (LMICs) by bolstering local production, technology transfer, and voluntary licensing. Support for the Pandemic Fund is noted, acknowledging the need for $10 billion to make the mechanism successful. Despite these encouraging commitments, the adopted declaration does not include specific new financial pledges for the Pandemic Fund nor targets that ensure the realization of the 100 Days Mission Plus, an initiative that would seek to develop and distribute MCMs within 100 days of an outbreak. Some were also hoping to see the declaration lay out some key principles or targets for a potential MCMs platform to succeed the Access to COVID-19 Tools Accelerator, which coordinated and oversaw the rollout of COVID-19 technologies to low-income countries. But while leaders emphasized the importance of achieving equitable access to essential tools in their statements, disappointingly, there was no mention of a platform in the final declaration text, and the idea was hardly mentioned by member states during debate. Instead, it was clear from the statements leaders made at the meeting that they are eyeing the ongoing processes in Geneva on a pandemic accord and reforms to the International Health Regulations (IHR) to resolve many of these issues—further increasing the stakes for the outcomes of these processes, which need to be aligned with each other and with the declaration.Lack of progress on UHC implementationThe UHC meeting began with the adoption of a nonbinding political declaration by member states. During the meeting, issues of equity and access took center stage. Various countries emphasized the importance of ensuring that health care and health products are accessible to all, regardless of income, and advocated for gender-inclusive health interventions.The role of R&D in achieving UHC emerged as another central theme. Many countries highlighted the need for local and regional production of vaccines, diagnostics, medicines, and other health technologies. Several member states stressed the importance of technology transfer to LMICs and the removal of barriers posed by intellectual property rights. Collaboration and innovation were identified as key drivers of improved global health outcomes. In alignment with the sentiments coming out of the previous day’s PPPR HLM, this reflects a growing recognition of the importance of regional and domestic capacity for health care production and innovation.The spotlight on R&D in the broader UHC context is an exciting step in the right direction, but like the PPPR HLM, the UHC discussions lacked targeted commitments. Member states focused on identifying gaps and areas of needed improvement, such as localized manufacturing of health technologies and increased investments, but largely failed to pledge new financing and other concrete commitments to fill these gaps.  TB commitments finally include tangible targetsThe week culminated with the TB HLM adopting a political declaration, setting forth targets and commitments for tackling TB. In the document, governments pledged to mobilize at least $22 billion annually by 2027, with a more substantial commitment of $35 billion annually by 2030 for TB prevention and treatment. Additionally, there was a commitment to mobilize an additional $5 billion a year by 2027 for TB research and innovation. These commitments are ambitious, especially given that governments have delivered less than half of the $13 billion they had committed to raise by 2022 during the 2018 HLM. Similarly, only half of the $2 billion pledged annually for TB R&D has materialized.While many in the TB community celebrated the adoption of the declaration, it is important to note that the document does not go as far as some advocates would have liked, particularly on equity and inclusiveness provisions, and others have expressed disappointment about the lack of engagement from heads of state. That said, the ambitious funding targets set forth in the declaration hold the potential to make a significant impact if they are met with concrete actions, accountability, and global leadership. Now, the challenge lies in holding governments accountable for their commitments by putting in place robust monitoring mechanisms to track progress.So where do we go from here? With all three political declarations adopted at the HLMs, the General Assembly must formally ratify them in the coming week, and there could still be fights ahead, as several member states lodged objections ahead of the summit. The UNGA HLMs shed light on the global community's priorities on PPPR, UHC, and TB but also gave insight on the lack of concrete commitments from member states. Heads of state were disappointingly underrepresented in all three. Statements from ministers were verbose on gaps and needs but short on commitments and implementation.Zooming out to the broader ecosystem, it is reassuring to see alignment between multilateral bodies, such as the G7’s promise to foster innovative technologies for TB and other diseases, acknowledging the need for advancements in this critical area. In fact, one of the major concrete announcements of the week was the government of Japan launching its Impact Investment Initiative for Global Health (Triple I for GH), a new G7 initiative that seeks to align private and nonprofit stakeholders around best practices for impact investment in global health. Finally, the G20 also reaffirmed its commitment to combat TB and other diseases and to support the interim MCMs platform under development by WHO.While the HLMs were significant milestones, the true test lies in the implementation of commitments. With the political declarations being nonbinding, it is now up to other multilateral bodies to pick up the baton and ensure targets are established, commitments are made, and leaders deliver on implementation. Looking ahead, the deliberations around the pandemic accord will next take center stage through the intergovernmental negotiating body on the pandemic accord, with the process set to conclude by next year. Several member states hope this will serve as a vehicle to advance discussions on the development and access to MCMs. Similarly, IHR reforms offer a chance to advance key elements of the PPPR agenda, such as data sharing and other core capacities.  The G7 and G20 will also need to play a bigger role in financing all these ambitions.The HLMs ultimately served as a good reset moment to reemphasize the importance of these global health priorities, but it is now up to other forums and national governments to work collaboratively to translate pledges into action.
