Vaccinating a pregnant ***** - What to watch for in mom/puppies?

I run a rescue organization, we just pulled a pregnant mom from a high kill shelter that was going to be euthanized so the shelter didn't have to deal with the puppies. She looks like she's due any day now - She was vaccinated with DHLPPV - C vaccine + Bordetella by the shelter when she was admitted despite the fact that she was pregnant. She was vaccinated about a week ago, so I'm guessing she was about 6 - 7 weeks along (obviously since she came from the shelter, until she delivers I really have no way of knowing exactly when she was bred or when she's due). I know the distemper vaccine can cause neurological problems and vaccines can cause abortions - Obviously she didn't abort, so what other problems do I need to watch out for with her, and in her puppies as they develop? She's a 10 lb Chiweenie (and that's pregnant - So probably 8-9 lbs without the puppies!)
