This really is the issue. While we had a Hodge-Podge of restrictions across the nation rolled out to try and control covid-19, too many Americans elected not to follow even the most minimum restrictions. And I have no idea when or IF a vaccine will be available, but I suspect people wanting it to go on a cruise are going to be at the bottom of the priority list, behind Health Care Workers, those at risk etc. I have a hard time believing that a vaccine will be ready and in adequate supply for recreational travelers to get shots until 2022 or maybe 23.
