We recommend guests are up to date with all vaccinations as recommended by their healthcare provider. Information regarding required vaccinations for a specific itinerary such as Yellow Fever, is listed in the pre-cruise documentation. Vaccination requirements vary by destination and change periodically. Guests should check with their travel advisor or the United States Centers for Disease Control and Prevention (CDC) at www.cdc.gov/travel to verify current recommendations. You are responsible for determining the vaccination requirements at time of sailing.
