One of EXIMIOUS’s main objectives is to develop a toolbox catering to diverse stakeholders, facilitating their understanding and use of the project’s findings, outcomes and results. This toolbox will provide resources tailored for patients, researchers, policymakers, and decision-makers, empowering them to generate data and insights, even beyond the end of the EXIMIOUS project. It focuses on the exposome and immunome, as well as clinical and societal ramifications, crucial for shaping effective policies.
