Virgin Voyages is the latest cruise line to announce that all crew and guests must be vaccinated against COVID-19 before sailing. Tom McAlpin, Virgin Voyages' CEO, said "The is a step towards the safe return to sailing and is the right decision for Virgin Voyages. We're really encouraged by the latest rollout plans in the May time frame from the new administration, and we know the future is about vaccinations. Our business makes us uniquely set up to do this with testing and vaccine travel requirements."
In addition, on March 17th, P&O Cruises has announced a vaccine requirement for guests as well. This applies to their newly launched cruises solely for UK residents. While most cruise lines require that guests' vaccine regimen be completed 14 days before departure, to allow plenty of time for immunity to kick in, P&O is allowing guests to sail within 7 days of their vaccination. P&O said that the decision was made due to the "advanced progress of the UK vaccination program and strong expressed preference on the part of our guests."
For Great Lake Cruising only one cruise line has announced a requirement that all guests be vaccinated. Pearl Seas, Viking Expeditions and Ponant have said they will have comprehensive testing, but Victory Cruise Lines announced they would require 100% of crew and guests to be vaccinated before sailing.
