Cholera remains a severe diarrhoeal disease that can kill within hours if untreated. Despite being preventable and treatable, cholera continues to cause major public health crises, with over 730,000 cases and 5,000 deaths reported globally in 2024, the majority in sub-Saharan Africa. Climate change, extreme weather events, fragile healthcare systems and inadequate WASH infrastructure exacerbate the persistence of cholera and undermine existing control strategies. Although oral cholera vaccines have proven effective, global shortages and waning immunity highlight the urgent need for complementary interventions. HUNADIA addresses this gap by developing and clinically validating a novel oral antidiarrhoeal treatment (VR-AD-1005, “VR”) that directly neutralises cholera toxin-induced fluid loss, where rehydration and antibiotics fall short. Building on a successful Phase II trial in Bangladesh, which demonstrated an eightfold reduction in stool volume and halved hospitalisation times, HUNADIA will conduct a large-scale, adaptive Phase IIb/III, placebo-controlled trial across 7 high-burden SSA countries. The trial will generate robust evidence on safety, efficacy and clinical utility, including in vulnerable populations. Our multidisciplinary consortium unites 11 partners from Africa, Europe and Asia, spanning drug discovery, GMP manufacturing, late-stage clinical research, health economics and policy translation. By strengthening African clinical trial capacity, engaging with all stakeholder groups and integrating climate-health data, HUNADIA is uniquely positioned to deliver a scientifically sound, clinically effective, cost-efficient and socially accepted solution. By reducing cholera morbidity and mortality, alleviating the burden on health systems and enabling rapid outbreak response, HUNADIA will contribute directly to epidemic preparedness, affordable access to innovations, and the Global Task Force on Cholera Control’s 2030 elimination roadmap.

PUREMIND will deliver the first Integrated Mental Healthcare Ecosystem (IMHE) to predict/early identify Mental Health Disorders (MHD) and create more optimal personalised interventions to prevent MHD and thereby improving wellbeing in children, adolescents, and young adults (0–25 years). The ecosystem will mitigate key challenges associated with MHDs, specifically 1)Detection: 1 in 7 undetected and untreated MHD cases, 2)Efficiency of treatment: lack of tools and guidelines for personalised multidisciplinary interventions that work, 3)Access to Support and Care: long waiting times for care due to lack of trained personnel, 4)Inequality: disparate and inadequate inter- and intra-country mental healthcare services and 5)Modern Cultures and Lifestyle: the increasingly recognised risk factor of digital addiction resulting in sedentary, socially isolated lifestyle contributing to MHD. These will be addressed by PUREMIND’s approach of combining analytical modelling of dynamical systems in the cyber-physical context of a subject’s personal natural environment-gene-gut-brain-MHD interactions process creating a much-needed personalised intervention synthesis framework that will be exploited by an AI engine to deliver optimised personalised intervention, and a unique digital twin educating young people how MHD might develop depending on their environment and lifestyle. These 2 components will be combined in an accessible/ adaptable mobile app MyMind to measure at scale and allow a subject to seamlessly access a 4-tier service architecture involving family, community, clinical and emergency services, to support prediction/early detection of MHD, empowering them to monitor their own mental health at home/educational/community settings and taking preventive actions against MHD. The IMHE will be designed using Implementation Science approach and will be validated in a 12month pilot study in 7 European countries and 2 LMICs covering different socioeconomic and cultural scenarios.

Climate change is one of several drivers of recurrent outbreaks and geographical range expansion of zoonotic infectious diseases in Europe. Policy and decision-makers need tailored monitoring of climate-induced disease risk, and decision-support tools for timely early warning and impact assessment for proactive preparedness and timely responses. The abundance of open data in Europe allows the establishment of more effective, accessible, and cost-beneficial prevention and control responses. IDAlert will co-create novel policy-relevant pan-European indicators that track past, present, and future climate-induced disease risk across hazard, exposure, and vulnerability domains at the animal, human and environment interface. Indicators will be sub-national, and disaggregated through an inequality lens. We will generate tools to assess cost-benefit of climate change adaptation and mitigation measures across sectors and scales, to reveal novel policy entry points and opportunities. Surveillance, early warning and response systems will be co-created and prototyped to increase health system resilience at regional and local levels, and explicitly reduce socio-economic inequality. Indicators and tools will be co-produced through multilevel engagement, innovative methodologies, existing and new data streams and citizen science, taking advantage of intelligence generated from selected hotspots in Spain, Greece, The Netherlands, Sweden, and Bangladesh that are experiencing rapid urban transformation and heterogeneous climate-induced disease threats. For implementation, IDAlert has assembled European authorities in climate modelling, infectious disease epidemiology, social sciences, environmental economics, One Health and EcoHealth. Further, by engaging critical stakeholders from the start, IDAlert will ensure long-lasting impacts on EU climate policy, and provide new evidence and tools for the European Green Deal to strengthen population health resilience to climate change.
