I'm going to play devil's advocate to explore my own anxiety about this situation.
My fears are exactly the same as yours.
The part that I cannot reconcile is this: I took my initial doses of vaccine, I had a booster. I did all the right things in terms of minimising exposure and the risk to myself and my family.
I still caught CV19 twice. Maybe it didn't affect me as intensely as if I had not been vaccinated, who knows, but it fucked me up badly each time.
My entire family have lived the same experience.
Most people's thinking in my circle now seems to be: why would I expose myself to the risk of cardiovascular complications by being continuously vaccinated, when I am still going to get infected and face those same cumulative cardiovascular risks again.
From a risk management perspective if I am not in a disease cohort likely to face mortality from infection, am I not reducing my total risk by simply reducing my exposure to the spike protein overall and electing to skip vaccine boosters altogether? I am going to get infected either way, that much is clear.
I am massively concerned about the long term consequences of repeated infection with this pathogen but it seems the world has moved on from giving a fuck.
I don't know a single person who has received a booster in the last 12 months and given the shift in media narrative here it is not hard to see why.
