Royal Caribbean International and Celebrity Cruises made it easier to get vaccinations on sailings.

Royal Caribbean ships do not require Covid-19 vaccinations for cruises departing the U.S.

Royal Caribbean does not recommend that guests are not up to date on their immunizations. A negative test result will need to be taken within three days of boarding for guests who are not fully vaccine free.

Vaccination is not required for sailings departing from Los Angeles and Europe. A negative Covid-19 test result is required for most sailings.

The changes came just days after the three Norwegian Cruise Line holdings (NCLH) brands relaxed vaccination and testing protocols and allowed unvaccinated people to cruise with a negative test from most destinations.

Royal said that some destinations it visits require that passengers be up-to-date with their vaccinations, and that those who don't meet those requirements may need additional testing on board.
