Survey data on Vaccine hesitancy in my part of the world:
Some ~88% are vaccine-accepting (not all of those are fully vaxxed) and ~12% are vaccine-hesitant.
Of those fully unvaxxed, ~80% believe they'll never catch Covid (sounds familiar?).
Some of the remaining 20% are probably unvaxxed due to logistics, inconvenience or peer pressure - they'll probably get vaxxed if it were more convenient and were vaxxed in groups (aka sheeple).
On the whole we're doing OK, but it will still take some work to get the message across to the ~12%. Another Covid wave would help in convincing some of the fence-sitters.
