My mare was vaccinated early in her preg. and
reacted to the vaccine,( of couse, she is the ONLY one my vet has had react),
and aborted. She had her initial preg. ultrasound and WNV at the
same time, then ran a low-grade fever,lower lip hanging down, and looked
like she had Parkinson's for two days. Then,two weeks later, ultrasound showed
her open.
I don't think I would be too worried if she kept
the preg., deformities can happen in any foal! Good Luck!!
