This is correct. Avoid using MLV on pregnant cows of unknown vax history.
If your cows/dams are pregnant, I'd use Virashield 6 on the calves and Virashield 6 + L5 (both killed). If they are open and you want to introduce modified live vaccines, I prefer Vista Once or Bovilis Nasalgen 3-PMH for the calves and Vista 5 VL5 SQ for the cows.
