Immunity isn't one thing that wanes.

T-cells are largely permanent and cross-reactive. Somatic hypermutation means that you have B-cells to variants which don't exist yet which can be quickly activated if you encounter them.

There's more to the immune system than circulating NAbs.

The 2009 H1N1 flu pandemic was a bit of a nothingburger because after mutating in pigs for at least 50 years, people born before 1957 still had cross-reactive T-cells to the H1 protein so old people were already immunized.

This is not the human immune system's first goat rodeo with a pandemic virus.

That's your choice, and it's your right, but it's absolutely bonkers, and if you think it should be mandated, you're a totalitarian.

Life is a risk. You have a lower chance of serious outcome -- assuming you're relatively healthy and younger than 80 -- from the extant strains than you have risk from driving. You can choose to face the risks of life and live, or grow old and die sad and scared.

I choose to be inspired by my wife's courage in the face of her brain fog. Our time on this planet is limited, and spending it afraid is a waste.

There are reasons to believe this public will be more than typically keen to consider, in general, risk mitigation.

Risk awareness does not bring «sadness» - on the contrary, it brings relief. Surely, many will also be «scared»: but that is not because of /one's own/ risk mitigation practices - it is an effect of "looking around". In fact, «spending... limited time on this planet afraid» is pretty much an objective perspective. It may avoid you worse predicaments.

And for the ever present mention of «risk from driving»: there are Cost/Risk/Benefits considerations involved. Easily, renewing them may not bring to a reconsideration of the advantage of driving.

I'd rather spend my risk budget on things more interesting than showing my chin off at the grocery store.
