How does anything about vaccines show that?
I understand your view to be that government imposed lockdowns were important and the right thing to do, because it stopped people from catching Covid and dying.
My view is as I said before, is that those at risk should quarantine themselves. And there should be no government imposed lockdown.
Your counterpoint was that the risk group includes much of the population due to age and obesity.
My response was that in my community, many had natural immunity and lockdowns were particularly unnecessary. (And especially harsh due to the communal nature of our culture.)
You said that natural immunity wears off. I said, so what? Vaccines wear off, too. That doesn't give a reason to lock us down. I will add that studies done in recent months have declared lockdowns worthless in stopping the spread.
