Last week, rain clouds gathered over Geneva as delegates from all over the world completed their annual pilgrimage to the World Health Assembly (WHA), the World Health Organization’s (WHO’s) annual forum for the 194 member states. The somber background reflected the mood heading into the meeting, as many were expecting this year’s gathering to be a washout. A visibly weary WHO Director-General Dr. Tedros Adhanom Ghebreyesus expressed his disappointment on the opening day that negotiations on a pandemic accord had not been completed in time for a WHA vote. Representatives also expected contentious fights over sexual and reproductive health and geopolitical conflicts, such as the ones in Ukraine and Gaza, to spill over into the proceedings, freezing debate and derailing possible progress on agenda items ranging from climate and health to universal health coverage. Yet, despite some serious bumps in the road, WHA also showcased that any multilateral system obituary is premature and that multilateralism can still deliver the necessary change we need to advance the global health agenda.   WHA approves new IHR amendments, resets timeline for pandemic agreement negotiationsAll eyes were on whether member states could come together to finalize the negotiations around the pandemic accord, a proposed convention to address some of the shortcomings exposed during the COVID-19 pandemic, as well as amendments to the International Health Regulations (IHR), an existing framework that codifies member state and WHO responsibilities in preparing for and responding to a public health emergency.  Heading into WHA, many stakeholders waited with bated breath to see if member states could bring both these processes across the finish line. Unfortunately, despite two long years of grueling negotiations, countries were unable to forge sufficient consensus to approve the pandemic accord. Instead, countries agreed to extend the mandate of the intergovernmental negotiating body, which coordinates the deliberation process for another year, providing additional time to reach compromises around the most contentious issues (financing, technology transfer—the process by which knowledge is transferred from the originator of a technology to other manufacturers to support the diffusion of health technologies into additional markets—, and a proposed access- and benefit-sharing system, which would pair commitments by countries around the sharing of pathogen samples and sequencing data with commitments from manufacturers to set aside a dedicated portion of their products for equitable distribution during health emergencies).  Nonetheless, member states notched a desperately needed win in reaching consensus on amendments to the IHR, achieving an agreement in the final hours of WHA. The consensus takes on added significance given that country representatives were not only in a race against time but also against fast-eroding trust in multilateralism, which was deeply fractured by the pandemic and subsequent geopolitical conflicts. The amendments to these technical rules, last revised in 2005 following the SARS outbreak, represent the first significant change in international law in the aftermath of the COVID-19 pandemic. While there were many changes to the IHR, one that stands out the most is that the added provisions include a commitment to solidarity and equity on strengthening access to medical products and to financing, including specific text that directs countries to promote research and development (R&D) and strengthen local production of quality, safe, and effective relevant health products. The previous IHR did not include any mention of R&D or the need to ensure equitable access to new tools.   WHA reinvigorates maternal and child health agenda  Progress was also made on a couple of other fronts in Geneva. Alarmed by the stagnation of progress in reducing maternal and child mortality, member states passed a critical resolution committing to specific actions to prevent the deaths of women, babies, and children.The resolution, led by Somalia and other cosponsors, commits countries to tackle the leading causes of maternal and child deaths, particularly in the hardest-hit nations. In it, countries agreed to improve access to maternal health services, including sexual and reproductive services, and comprehensive child health services through stronger primary health care and expanded access to emergency services. It also urges countries to develop and invest in tools that enable access to essential quality medicines for pregnant women, lactating women, mothers, and newborns and calls on WHO to strengthen and expand collaborative efforts, such as those promoted by WHO technical departments and the Global Accelerator for Pediatric formulations, or GAP-f, network, for facilitating better access to medicines for children. The WHA resolution marks WHO’s first significant action on maternal mortality in nearly a decade, following the adoption of the Global Strategy for Women’s, Children’s and Adolescents’ Health in 2015. Antimicrobial resistance in the spotlight  Antimicrobial resistance (AMR) also was in the spotlight in Geneva. With the United Nations High-Level Meeting (UN HLM) on AMR taking place in New York in September and a high-level ministerial meeting in Saudi Arabia in November, this year has been supercharged with attention on the issue, with WHA featuring numerous AMR events, roundtables, and initiatives.  Delegates approved a resolution to accelerate national and global responses on AMR, with many of them highlighting it as a crucial building block for the meetings in the fall. The resolution welcomes WHO’s strategic and operational priorities to address drug-resistant bacterial infections in the human health sector, which include prevention of infections; universal access to affordable, quality diagnosis and appropriate treatment of infections; strategic information, science and innovation; and effective governance and financing of the human health sector response to AMR.  The resolution also calls on member states to support investments in R&D for new tools to combat AMR and replenish the shockingly waning pipeline, to strengthen the capacities and standards of laboratories, and to participate in the WHO’s Global Antimicrobial Resistance and Use Surveillance System, or GLASS.While WHA did ultimately feature some contentious moments, especially around the geopolitics of Ukraine and Gaza, and major pushback on sexual and reproductive health, the latter almost derailing the adoption of several key decisions, the wins on IHR, maternal and child health, and AMR will have reverberations beyond WHA. Delegates hope that these wins will provide the necessary momentum to continue to make progress on the pandemic accord and at the UN HLM on AMR in the fall.

There are currently no effective treatments for addressing severe bites caused by venom from the spitting cobra, which is responsible for a substantial portion of snakebites in Africa. The scientists found that repurposing the small molecule drug varespladib to target one of the two major toxins in the venom was effective, even when delivered up to an hour after the bite, and the drug also provided protection from venom-induced muscle toxicity.Newly shared research found that a dose-sparing mpox vaccine approach, which was used during the 2022 mpox outbreak in the United States as global vaccine supplies were stretched, is safe and effective. The study tested an intradermal mpox vaccination regimen in adults using the Jynneos vaccine containing either one-fifth or one-tenth the standard dose, finding the former was generated a comparable antibody response to the standard vaccine regimen. These findings underscore real-world data that have shown similar effectiveness for this dose-sparing intradermal regimen and the standard subcutaneous regimen. The new findings are also timely as a widespread mpox outbreak continues in the Democratic Republic of the Congo.Last week, Kephera Diagnostics announced that it received a two-year $606,498 grant from the US National Institutes of Health to help fund the development of a point-of-care test for congenitally transmitted (or mother-to-child transmitted) Chagas disease, which is believed to be the primary transmission method of the disease in the United States. The company will use the funding to develop a point-of-care blood test that can be used to diagnose infection at the point of delivery by measuring the levels of the antibodies that are believed to be the first to appear in the blood in response to infection and can be differentiated from maternal antibodies. Congenital Chagas can be treated with two drugs that are approved for pediatric use, but because the disease is often asymptomatic in newborns, it can resemble the symptoms of other infections and be hard to correctly diagnose.

Malaria is one of the world’s oldest and deadliest diseases. Thanks to international efforts to develop and scale up prevention tools and treatments, significant gains have been made over the past few decades in fighting this dangerous disease. But challenges, such as growing drug and insecticide resistance, climate change, and disruptions from COVID-19, have hampered control efforts. While both malaria cases and deaths steadily declined from 2000 to 2019, since then, cases have been on the rise and reported deaths have not returned to pre-pandemic levels—indicating progress against the disease has stalled and underscoring the need for continued research and development of new tools.In recognition of World Malaria Day, test your knowledge of this deadly disease and the innovations being advanced to end malaria:

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.
