Interesting question. But... we need to wait. What will be the effectiveness of the vaccine? You can get the vaccine, have little to no side effects, but like the flu vaccines some years, it is only 30% effective. So you still may get sick, maybe not as severe, but still have outbreaks about cruise ships. For people to not get sick at that point, you would need most people to get/have been vaccinated. That is going to take awhile. I don't know if I will get the vaccine right away and I am not sure when my family may be eligible. Not sure you can require it if a vast majority can't obtain it. Dealing with this virus and our ability to cruise, I believe, is going to take more than just a vaccine. I hope we can figure it out soon, not just to take my cruise vacation at some point, but to return to a more normal way of living
