We offer a useful science experiment. We are the second most vaccinated country after Israel. (I'm excluding countries with Chinese vaccination programmes because they don't work).
Do the vaccines protect people well enough to return life to normal?
So far, it looks to me like we are able to live a more-or-less normal life again. Mortality rates overall are not impacted in such a way that the country must be locked down.
But personally, I'll keep wearing a mask in shops.
