A store can put up a rule: no firearms in this store, even if they are legal in this state) Ultimately the person decides for him or herself whether to be vaccinated. But there may be consequences based on that decision. Are you asking: should or shouldn’t there be consequences for personal decisions? That’s a whole different discussion that goes way beyond Covid.
