The Covid-19 pandemic further exposed humanity's vulnerabilities while exacerbating pre-existing inequalities. However, it also highlighted its strengths, not only in terms of vaccines created in record time (although terribly unevenly distributed), but also in highlighting the importance of health systems. The SOLIVID initiative, composed of 34 research groups from Latin America and Europe, was created in April 2020 as a metadata system for international solidarity actions that emerged in the context of the pandemic. In this book, published in collaboration with the Autonomous University of Barcelona, 43 authors seek to study and disseminate these collective solidarity actions, providing elements for debate and resources for a panoramic analysis.
