A few cattleman were discussing vaccinating cows this morning. Seems there was some disagreement on if you should vaccinate cows in early pregnancy. A few said that vaccinating even with killed vaccine in early pregnancy (now through 90 days) might cause absorption of the embryo.  Others said it wasn't the vaccination but the actual process of working the cattle through the pens/alley/chute, even if they were handled gently and easily.
So, what is everyone's opinion?  They are vaccinated with Tri-View, vira-shield9VL5 + Harjo.  Calves are vaccinated with Tri-View, Vira-shield 6, alpha-7, and one-shot.

The discussion started when one said they had preg checked and vaccinated in July, and then preg'd again in Oct and found 10-14% were either open or short bred and yet they were confirmed 30-70 days bred in July.  (Ultrasounded both times)

Different vaccines will have different rules.  When in doubt READ the vaccine inserts (don't just assume) and check with your veterinarian.

My herd has been a MLV herd for over 7 years, only MLV vaccines allowed (pertaining to viruses, and the mannheimia and pasturella).  I still want my cows to have 30 days of no needles before breeding, carriers can cause increased immunity action and I only have one chance to AI.  This method has worked well for me, but it can be challenging at times.  Heifers always get two rounds 60 and 30 days before breeding and sometimes another at 45 days just for giggles.
