The Twenty-Seven said yes Thursday evening to a mechanism strengthening the control of vaccine exports from the EU, taking into account reciprocity. The block exported 77 million doses abroad including 21 million to the United Kingdom, which sent nothing in return. But their yes has remained cautious. Germany, the Netherlands and Belgium fear a “boomerang” effect and do not want to break the supply chains of vaccines or vaccine components that they import. The device should therefore be used as a “last resort”, said Belgian Alexander de Croo.
