The European Union has launched its digital Covid certificate, to allow European citizens to travel across the bloc.
The move is designed to reduce the need for quarantines, and boost tourism over the peak summer months.
Citizens from outside the EU can enter if they've been fully vaccinated with a jab recognised by the EU's health regulator.
Lucy Hough has more from Brussels.
