Also agree here, if the population is living under restrictions then a lower figure than expected could be true. That number will be higher with no restrictions at all, due to more activity overall. For me herd immunity is only a way to persuade politicians to remove all restrictions so that we can resume our lives. And Corona vaccine passes do not have any place in this last scenario.
