I originally posted the cruise ship story because it was an illustration of a 100% vaccinated community whose vac status did not prevent the spread of covid. You also decided to jump in on the outbreak definition discussion and got out a bit too far over your skis.That wasn't why the cruise ship was brought up. It was brought up to pretend I'm an idiot and poke fun at my references to math when discussing that, statistically speaking,100% vaccination could end the pandemic.
