I think you'd be surprised... most of my colleagues and friends have been vaccinated to stop the spread and get things open again. We're all in our 30s still and many have kids who won't get to be vaccinated for a long time so they won't be "safe" afterwards. Our parents already got theirs (my state went by age after offering it to healthcare workers first in the beginning) so really there is no "need" for us all to be vaccinated. Still did it.
That said, if Hawaii decides the test isn't necessary if you've been vaccinated I will be pulling a "Lilu Dallas multipass" with my vaccination card as I walk on by!
