I am one of them.

As someone with zero risk factors, I was never afraid of catching covid myself. I was also firmly against mandates of any kind. However, I rolled the dice and took the vaccine anyway. At the time I concluded that the vaccine a) reduced transmission and b) had little downside. I also required the vaccine for travel so I could care for family.

It was not safe. I felt dreadful after the shot, and had occasional heart palpitations for a few months. Who knows what the long term effects are? Certainly the excess death rates among young men are not an encouraging statistic (and of course you won't find figures including vaccination status).

It was not effective. In fact, I caught covid a mere 3 weeks after the shot.

Taking the vaccine is perhaps one of my biggest blunders and regrets. It did worse than nothing for me and was an unnecessary gamble. I give props to the people who saw through the bullshit better than I did.

One hopes there are many.

And to "premature and unnecessary" I would add "profit driven" and "unscientific"
