In Germany at least, those vaccinated get a Yellow vaccination certificate (looks more like a booklet) which is internationally recognised. Each country in EU is having their own!
But EU is soon launching a Digital Green Certificate to facilitate the safe free movement of citizens within the EU during the COVID-19 pandemic. Digital Green Certificates will be valid in all EU Member States.A Digital Green Certificate is a digital proof that a person has either:
– been vaccinated against COVID-19
– received a negative test result or
– recovered from COVID-19
