🚨 Very, very big news. Today, a global coalition - including members of the IPCC, IPBES, and WHO expert advisors, as well as independent virologists, epidemiologists, and lawyers - started the process of creating an "IPCC for Pandemics." 🔓 www.thelancet.com/journals/lan... 🧵 Five things to know 👉
Pathways to an Intergovernmental Panel on Pandemics: lessons from the IPCC and IPBES

Colin J Carlson, Christopher H Trisos, Ben Oppenheim, Shweta Bansal, Sara E Davies, Aïda Diongue-Niang, Victoria Y Fan, John D Kraemer,

Laura M Pereira, Benjamin Roche, Matiangai Sirleaf, Kayla Zamanian, Carlos Zambrana-Torrelio, Alexandra L Phelan

Pandemics pose a global threat to human wellbeing, justice, economies, and ecosystems and are comparable with other planetary crises such as climate change and biodiversity loss in terms of urgency and impact. The global community would benefit from a dedicated scientific synthesis body to assess pandemic risks and solutions. In this Personal View, we explore proposals for an Intergovernmental Panel on Pandemics and assess potential pathways to its creation. Learning lessons from the Intergovernmental Panel on Climate Change (IPCC) and the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) might help national governments and international organisations to chart a course through important decisions about format, governance, operations, scientific scope and process, and ability to recommend policies that make the world safer.

An update from the team on the uncertain future of our program and the impact of NSF budget cuts. Please share and reach out 🦠
Some difficult news from the team:

In NSF's FY25-26 Budget Request to Congress, we learned that our program will take a whopping 50% cut - meaning that in September, we'll be $1.25m short of an operating budget that currently supports a cohort of seven PhD students, four postdocs, and three full-time staff.

Verena is one of the largest and last pandemic prevention-focused programs in the United States: since 2020, we've supported the training of over 60 postdocs, graduate students, and undergraduates. Our researchers have established unique laboratory resources for studying animal immune systems, and discovered new antiviral immune adaptations in bats; developed risk assessment algorithms for wildlife and livestock viruses, and diagnostic algorithms for viruses like dengue, Ebola, and Zika; and quantified the effects of climate change, deforestation, and factory farming on spillover risk. Everything we develop is 100% open source, and our data has supported the research of nearly 150 external researchers in 21 countries to date.

We have three months to make up our budget shortfall. Every dollar spent on Verena supports not just our team, but the community of researchers who use our data, code, and resources. You can help us by sharing this post, and reaching out if you're able to support a unique and vulnerable program. Or just head over to viralemergence.org, and take a look at what we do. 🦟 🦇 🦠

Turns out, that's only seven studies between 1961 and 2024. Still, a fair bit of work to extract the data, summarize it, make sense of methodological differences, and come to a conclusion about public health risks. Our open data initiatives can save us some time on #1 and #2 before outbreaks start.
