COVID-19 Test Result
Travelers must provide evidence of a negative result for SARS-CoV-2 that has been conducted within 3 days of boarding the ship in Greece. Proof of a negative test is not required however for all travelers that have completed their vaccination(i.e., 14 days have elapsed since the last vaccination, depending on the doses required) and hold a vaccination certificate.
That is what it says under Greece under Explore well at sea on the website as from 11th May. So does that mean tests are no longer required if you are vaccinated? It’s very confusing.
