Should I re-vaccinate/

[HappyPalace]

Background: Last summer my refrigerator died - it started warming things instead of cooling including my bottle of CDT. Replaced the fridge and the bottle of CDT just to be sure. October comes and we need to booster our Katahdin ewe. The old CDT is in a ziplock bag in the fridge awaiting my ability to find a place to dispose of old medications, etc. My daughter used THAT vaccine instead of the new one. After yelling at her for not thinking she said, "Well, I missed with 1/2 of it anyway because she jumped."

It's been almost 2 weeks and the ewe doesn't show any signs of a problem. Should I re-vaccinate with the good CDT or just assume since she's not dead that the old one was okay?

It's unlikely that the old vaccine would hurt her (as you have witnessed) just lose it's efficiency. But, I would re-vaccinate. Good luck!

Re-vaccinate and throw out the old vaccine. Never keep spoiled or outdated meds around to prevent this kind of mix-up.

Thanks! I appreciate your help. We'll re-vaccinate.
