The EU Digital COVID Certificate (available as of 1 July 2021) provides proof that a person has either:
Certificate of vaccination: attesting to a complete vaccination pattern against Covid-19, established in accordance with article 3bis, paragraphs 1 to 2, of the amended law of 17 July 2020 on measures to combat the Covid-19 pandemic. Namely a vaccination certificate issued by the Grand Duchy of Luxembourg, a Member State of the European Union or the Schengen Area. Certificates issued by certain third countries are also accepted provided that the vaccine administered is accepted by the Grand Duchy (this currently applies to certificates issued by the following countries or territories: Albania, Andorra, Armenia, Brazil, Cabo Verde, Canada, El Salvador, Faroe Islands, Georgia, India, Israel, Japan, Lebanon, Moldova, Morocco, Monaco, New Zealand, Panama, Republic of North Macedonia, San Marino, Singapore, South Korea, Togo, Turkey, Ukraine, United Arab Emirates, United Kingdom, United States of America, Vatican).
A complete vaccination pattern means any pattern that defines the number and interval of injections necessary to achieve sufficient protective immunity and is complete upon administration of the required doses if multiple doses are given or, for single-dose vaccines, after a 14-day interval. For persons who have recovered and have been vaccinated within 180 days of the first positive NAAT test result, the vaccination pattern is complete 14 days after the administration of the single dose of any vaccine administered.
