Vaccination requirements for cruise ships: some now require booster shots

As cruises continue to make headlines for the rapid spread of COVID on board, more and more companies are tightening requirements for passengers. Now three cruise lines, Azamara,Silversea Cruisesand Lindblad Expeditionsall announced updated vaccination requirements for passengers.

These small luxury liners will require reminders for passengers who received their initial dose of the vaccine more than five months ago, starting March 1. These three lines are the latest cruise lines to update their boarding requirements. According to The dot guyHapag-Lloyd Cruises, UnCruise Adventures, Viking, Grand Circle Cruise Line, Overseas Adventure Travel, P&O Cruises and Cunard Line are other companies that have added some sort of reminder requirement for boarding.

Reminder requirements have become more common in the world of travel. Several major destinations, including Spain and Singapore, have instituted recall requirements for travelers who received their initial dose of the vaccine more than 270 days ago.

These recall requirements from smaller liners may indicate that a requirement will become an industry standard, given that major liners like Royal Caribbean and Carnival already have vaccination requirements in place.
