I don't think you'll get any more functional immunity from an extra shot of vaccine compared to two and an infection. So the benefit side of the calculation is lacking.

While the vaccine risks are very small, they're also highest for those who have had the actual infection. There will be little bits of virus lingering in my body for a long time. If I get that vaccine, my immune system is going to go ape attacking them, and maybe do some collateral damage in the process.

To be clear, I still think the risk is small, but so is is the benefit. I don't think it's worth it.

Thanks for writing a detailed comment of your thinking, I think we both are evaluating it the same way, I just wasn't very clear with my initial wording.
