Cruise News 2021 - Should Cruise Lines Be 100% Vaccinated

so i read an article today advocating 100 vaccinations for all cruises it gave three big reasons why and honestly i think these reasons make perfect sense

the theory being that if everybody on the cruise ship was 100 percent vaccinated no that does not mean that kova 19 is not going to get on the cruise ship

if every single person is vaccinated the chances of somebody getting seriously sick seriously ill or any kind of mass spreading happening around the ship the odds of that are greatly reduced

the next logical step in my opinion is that they're going to go to a 100 vaccinated only cruising requirement just to try to increase the health and safety on board the ship
