Disney Cruise Lines will require all children over the age of 5 to be fully vaccinated against Covid 19.
The large family-focused cruise line will bring in the new mandate for sailings from January 13 next year, as the first major cruise line to do so.
This sees Disney pulling away from other cruise lines and the home countries of many guests who have not yet approved vaccines for those under the age of 12.
"As we set sail again, the health and safety of our guests, cast members and crew members is a top priority. Our focus remains on operating our ships in a responsible way that continues to create magic for all on board," said a statement from Disney Cruise Lines.
Currently Royal Caribbean International, MSC and Carnival allow children under 12 to sail with them, providing a negative Covid test.
