Do guests have to be fully vaccinated to sail? What proof of vaccination is required?

UK residents above the age of 18 who are fully vaccinated against COVID-19 (having had their final dose at least 14 days prior to departure) and those under the age of 18 with negative test results will be permitted to sail.  We are working closely with the local authorities and will advise booked guests closer to the sailing on what proof of vaccination is required. On arrival at the port vaccinated guests from the UK must display their vaccination status on the NHS App or provide a valid NHS vaccination certificate.
