Previously, the line required 90% of guests to be fully vaccinated – allowing for 10% of customers to be non-fully vaccinated.
From 18 September for sailings onboard Valiant Lady and from 21 September for Scarlet Lady, the cap will be removed and all passengers will be able to board regardless of their vaccination status.
However, non-fully vaccinated travellers will still be required to provide evidence of a negative Covid-19 test taken within 72 hours of embarkation.
A Virgin Voyages spokesperson said: "The health and safety of our sailors [guests] and crew are most important, and we’ll continue to emphasise our ‘Voyage Well’ protocols.
"We’re excited to see cruising make its way back to 2019 sailing levels and to welcome onboard both new and returning cruisers seeking a different kind of adventure on the high seas."
