Covid-19 pandemic Monday 28 December 2020, by Christian Zeller On 19 December, scientists launched an international appeal for the containment of the Covd-19 pandemic throughout Europe. [1] Trade unions, liberation movements and socialist organisations should unreservedly support this call and enrich it with a socio-ecological programme of demands. On this basis and inspired by the campaign #ZeroCovid recently launched in England, Wales, and Scotland they should launch mass campaigns throughout Europe. The authors of the appeal note that European governments have so far failed to formulate a common vision for dealing with the pandemic. However, in order to fight the pandemic effectively, a common European strategy is urgently needed. This is the only way to keep the borders open. The vaccines will take some time to get the pandemic under control, probably not before the end of 2021. The authors formulate a clear and immediate societal goal: every single SARS-CoV-2 infection in Europe must be traceable. To achieve this goal, the authors call for the implementation of a three-step strategy.
