Travelers presenting a valid international certificate for full COVID-19 vaccination, using an approved vaccine, are exempt from pre-departure testing requirements. The final dose must have been administered at least 14 days prior to departure.
Travelers can provide their EU digital certificate on paper or digitally as proof of vaccination, negative test result or prior recovery. Health documents provided in this way will not require additional verification on arrival. Full details on the EU digital certificate, including how EU residents can access their certificate, can be found at https://ec.europa.eu/info/live-work-travel-eu / coronavirus-response / safe-covid-19 -european- vaccines / eu-digital-covid-certificate_en
Upon arrival, proof of a negative PCR test must be presented, taken within the previous 72 hours. Alternatively, a negative rapid antigen test can be presented, taken within 48 hours of arrival. Instead, travelers can provide documentation of having recovered from COVID-19. This will require proof of a positive PCR or rapid antigen test result, taken within at least 11 days and no more than 180 days prior to arrival. Arrivals without health documentation must be quarantined for 10 days. This period may be shortened if a PCR or antigen test is performed within 72 hours of arrival and a negative result is confirmed and presented to the director of the respective regional health inspection.
Arrivals are subject to rapid random antigen testing at the airport.
