Are you referring to this study from 2023?

It did find a temporary but statistically significant increase in PSA levels after COVID-19 infection or COVID-19 vaccination, though these increases were very small in the absolute sense -- averaging about 0.03 to 0.09 ng/dL.

That study also specifically excluded men with prostate cancer, let alone men who'd received whole-gland treatment like you have. So it's not clear if the observed effect would also apply to someone in your situation.

That said, your last PSA check was low enough that even a 0.03 increase would be potentially concerning, so it might be best to postpone the vaccination until after 11/10. That's only a few weeks away anyhow.
