No.
We don't understand why COVID hits some people harder than others. We don't understand why some people end up with "long COVID" sequelae and some don't. I don't particularly want to roll those dice from immunological naivety.
The vaccines were free. The biggest risk I would have faced was myocarditis, and the risk even for that is higher from a COVID infection than from the mRNA vaccines.
Furthermore, getting vaccinated means that we all get back to a place where COVID is less of a big deal societally. While the data does show that vaccinated individuals can transmit Delta, it shows that they do so for a shorter period of time, and anything we can shave off of R0 is a good thing. Perfect, enemy of good, etc.
Getting vaccinated was close to no skin off my back. I had a sore arm for a few days. The payoff is that I reduce the (admittedly small) risk I did have, and I'm part of the herd boxing COVID in.
What's the downside?
