Virgin Voyages has removed its cap on the number of unvaccinated passengers allowed on a single ship, according to TTG Media.
Previously, at least 90% of guests had to be fully vaccinated at any time.
The new regulation came into force on Sunday (September 18) for all itineraries on board Valiant Lady and will go into effect from Wednesday (September 21) for Scarlet Lady.
Unvaccinated cruisers must still, however, show proof of a negative COVID test taken within 72 hours prior to embarkation.
