Have not heard anything addressed, and am keenly interested. Of our late June crew of 7, 6 of us will be fully vaccinated by then. My youngest daughter turns 16 a week before we are scheduled to travel and will likely have received her first jab prior to our departure, but definitely not "fully" vaccinated. In any event, we are prepared to deal with the realities if we are all subject to quarantine as a result. All for one, and one for all, etc...
