Proof of vaccination will be issued to around 1.9 million people from today ahead of the reopening of international travel on the 19th of July.
The Digital Covid Certificate can be used to travel at ease through ports and airports across the European Union.
They'll be issued to those who are vaccinated, have recovered from Covid-19 or who have a negative PCR test within 72 hours of travel.
Eoghan Corry Editor of Air and Travel Magazine says travelers who aren't vaccinated could face restrictions if a country has a spike in cases:
"The restrictions will apply to those who are unvaccinated. They will still be required to to take tests. Test right across Europe means antigen tests but on return Ireland is still requiring, as of today Monday morning, a PCR test on return. It remains to be seen will that change on July the 19th."
Vaccinated people will be sent an email from which they will be able to download a QR code which can be scanned at ports and airports. A certificate of recovery will be available from 11 days after a positive test, and will be valid for no more than 180 days. Travellers will have to request the cert from the dedicated helpline. Helpline details are not yet available but Government says they will be shared shortly.
