Authorities are guided by medical professionals in their response to epidemics. Dumb comment.
Anecdotally, I was vaccinated as being in the most vulnerable age cohort.
After the second vaccination, I got the delta version of COVID - perhaps the worst of the variants in terms of death rates.
My experience was three days of a runny nose and sore throat, finish. Was back to doing my cardio exercises a day later.
Since then, I have had two mRNA shots without any side effects, apart from an increased intolerance for fools.
My GF, 23 years younger than me, was unvaccinated. She takes a lot more notice of social media than I do.
She had the full gamut of symptoms for 11-12 days, and was seriously ill. After that experience, she could not wait to get vaccinated.
I also had a friend, anti-vaxxer. He contracted COVID about two weeks after me. It took him two months to recover from confusion and fatigue. Prior to COVID, he was walking 15 km a day.
Another statistic: The COVID death rate in the US red states rejecting vaccination is significantly higher than the blue states, I suppose you consider that is propaganda too.
