The Covid-19 pandemic is a multi-faceted crisis that challenges not only the health systems and other policy sub-systems in the single Member States, but also the European Union's ability to provide policy responses that address the transnational nature of pandemic control as a union-wide 'public good' that affects health and social policies, border control and security as well as topics related to the single market. Thus, the pandemic constitutes a veritable capacity test for the EU integration project.This article attempts to take stock of the Union's early reaction to the first wave of the Covid-19 outbreak. After an introduction and a short note on the scope and methodology of the analysis a theoretical framework is developed. Scrutinising the pertinent literature on crisis management, we reflect the traditional hypothesis that in times of crisis the centre becomes more relevant against the background of the EU crisis management system, and discuss the role of informality in particular during the time of crisis. Against this backdrop, empirical evidence from interviews with EU officials and documents in selected policy fields (health and emergency management, digitalisation, and economic recovery) are analysed, before a discussion and conclusion complete the study.
