I'm with you. Had my shots, but still being very cautious as I have been for a year.
For me to go back to a crowded space, I need a high percentage (80%) of the general population vaccinated and low positivity rate (2%) to make me return.
I realize those numbers don't magically make me immune and so many variables come into play, but as a general guideline those numbers would make me comfortable.
Or at least I think they would. At the moment it's hard for me to imagine sitting in a crowded theater. I hope my perspective changes as things evolve.
