The DGC is a European-wide initiative aiming to provide a vital tool towards enabling the safe travelling of European citizens across Member States. A DGC is issued at a national level for citizens that have been vaccinated, recovered from Covid-19, or have a recent negative Covid-19 test result. At the same time, Europe maintains a trusted DGC gateway for the exchange of the necessary information needed to validate a DGC. As a part of the national eHealth ecosystem, a citizen and/ or a personal doctor, via the eHealth4U platform, will be in position to request a DGC issuance that will be later stored to the citizen’s EHR.
