You might want to look at the UK data. Over 75% double jabbed, going on for 90% single jabbed, around 25k positive tests per day yet hospital admissions and deaths are low. We are suffering but we are functioning with the aid of ongoing public health measures. Most of us still mask up in shops and such, clean our hands and so on. It is not ideal, but things are returning to some semblance of normal.
