Evidence of full vaccination against Covid-19 or recovery from Covid-19 must be provided if required. The national authorities will decide whether there are exceptions to the required negative Covid-19 tests such as by a vaccination, for example.

Vaccinated persons

You are regarded as fully vaccinated when you can verify via an official certificate that you have been vaccinated with the required dosage of a vaccine approved at your destination. Please note that authorities set different guidelines for how long ago the last vaccination has to have been given.

  • An international vaccination certificate “International Certificate of Vaccination or Prophylaxis” (Yellow Card) or other officially issued vaccination records/ vaccination passports/vaccination certificates
  • A vaccination certificate that has been issued to you by the vaccinating authority (loose-leaf)
  • Officially approved digital vaccination certificate. The app-based solutions store the vaccination certificate as a QR-code that can be shown or sent as necessary.

Recovered persons

You are regarded as a person who has recovered from Covid-19 if, within the last six months, you have tested positive for SARS-CoV-2 through a PCR test and the test result dates back at least 28 days. If your test date is more than six months ago, as a rule you are no longer regarded as a recovered person.

As proof that you have recovered from Covid-19 (i.e. have overcome an infection with SARS-CoV-2), you can use the following documents, provided that these are accepted by the authorities of the transit or destination country:

  • Individual-related positive PCR result of a laboratory/testing site or a test centre
  • Medical certificate or isolation attestation, provided these contain details of the type of test and date of test/notification
  • Further certificates from the authorities provided these contain details of the type of test and date of test/notification
  • Official, internationally valid Health Wallets

Important: in principle, only an individual-related positive PCR test result is applicable. Further permitted procedures or formal requirements are stipulated by the authorities of the transit/destination country. Please find out about these accordingly.
