Dear Dr. O,
Is it safe to vaccinate a non-pregnant mare
with a modified-live vaccine for rhino
when a pregnant mare is on the same farm
and turned out together? I use the pneumobort
K (dead-form) for my pregnant mare but would like to get my non-pregnant mare up-to-date on her
shots before she leaves my farm for a large
breeding farm this spring. I want to make
sure she has some antibodies built-up before
she is exposed to the large, breeding farm
environment.
An old book I have titled, The Horse Breeding
Farm, that was written by a lady DVM stated the live form should not be used on any farm where pregnant mares were located as the vaccine could actually cause a low-grade infection capable of causing abortion in pregnant mares in the vicinity of the horse vaccinated. Does this still hold
true? Since my book is outdated, what is
the current school of thought on this subject
matter?
Thank you,
Sheryl |

I have gone to the equine site and have not seen the answer----if you vaccinate with intranasal (live) flu or strangles on your show horses how long do you have to separate the non-pregnant from the pregnant, or do you not use live on a farm with pregnant mares period. Thanks |

It is an excellent question Teri. Though we have covered the use of MLV herpes vaccines we have not covered the new IN ML flu and strangles. As we recently reported in the article on influenza the vaccine can be transmitted to other horses though not very efficiently. No such similar work has been done with the Strangles vaccine that I can find however. Until it is done I would assume it is transmissable and will be surprised if it is not. Until these vaccines are approved, or at least shown to be safe, for pregnant mares their use should be restricted around mares that are pregnant.
There are no known specific times for isolating recent ML vaccinates but I would suspect a month would be very safe, but I cannot guarantee it.
