Hmmm. 🤔 It will take a psychological and emotional disregard for my personal safety. Others will weight the risk to the tune of nimby. " I have certainly been exposed by now, and I haven't contracted it yet so I must be invincible" was what I heard from a twenty two year old last week. When the great event of returning to normal activities occurs and stepping onto a cruise ship will be one of them, I encourage you to look around at your fellow passengers and crew and remember human beings are resilient. Now as for " being in my late 70's, I wondering why I would get on a cruise ship with from 600 to 6,000 of my closest friends and feel safe without bein g vaccinated for Covid-19 " Don't !.... whether it's covid 19, 20 , saturn 5 flu, noro virus, last weeks left overs, your at risk as a senior being and your bod' is loosing it's will to fight. Even when there is a vaccine there is no guarantee it will work for everyone.
