There was a post in yesterday's FML about the recall of a batch of
Merial's IMRAB.  I noted that I couldn't confirm it.
 
A couple of people sent me more info about the recall privately.
 
In short, while that batch does have a problem, it's probably not an
issue with ferrets due to their annual vaccination schedule.  I would
suggest that your *veterinarian* call Merial if there are questions
and the vet is affected by that batch number.
