However, I can provide some general information:
* BVD (Bovine Viral Diarrhea) vaccines are generally considered safe for pregnant cows. The vaccines are typically inactivated, meaning they contain killed virus particles that cannot cause disease.
* There is no evidence to suggest that BVD vaccines cause abortions in pregnant cows. In fact, vaccinating pregnant cows can help protect their calves from the disease.
It's important to remember that individual reactions to vaccines can vary, and there may be rare exceptions. Always consult with a veterinarian for specific advice regarding vaccinations for your herd.
