I don't think it makes sense to re-audit, but I also think that you need some sort of verification process that the issue was properly addressed. For example, if it was a training issue, obtain the agenda from the training meeting.
I set up a "validation file," which was at the suggestion of our examiners long ago. I maintain any evidence that the finding was appropriately addressed in that log. For some issues the evidence is more tangible (i.e., was a policy/procedures updated per the recommendation) and for some the "this is where I'm at/this is what was done" response from management is what I use.
This from the Fed:
The audit department should determine
the reasonableness, timeliness, and completeness
of management’s response to their recommendations,
including follow-up, if necessary.
