They did for passengers everyone has to be vaxxed.. 5 and up ...
Every one over age 12 was fully vaxxed on ship, including the staff. The cruise finished without anyone getting sick with covid. Good times were had by all. One passenger had a life threatening emergency on the night before disembarking day. The ship stayed in Nassau for 3 extra hours in case the passenger needed to be transferred to local hospital in Nassau from ship’s infirmary. Captain announced the passenger was doing well and it was not covid related. I am guessing a heart attack.
