Dr. O.,
I read your articles on vaccinations and pregnant mare care, but I didn't see anything about what to do before you breed, other than the normal vaccines. Is there any difference? I have not given either of my horses flu/rhino(Is this EHV-1 and 4?) this year as they both reacted to that shot last year (mare got really sore and stiff for about a week). Should I give her the shot anyway? Also, my gelding had a severe reaction to it last year, and he lives in the stall next to her. Should I vaccinate him too? I was thinking I could preemptively help by buting them both before giving them the shots, but would this help?
Thanks,
Alicia

Before you breed, the regular vaccines should fit the bill. You had three horses react to the EHV 1/4 injection? I give hundreds of doses of this a year with pregnant mares getting it 3-4 times in a year without remarkable reactions. I have a few horses in the practice that get sore following their yearly (not sure which vaccine). You may want to look at the way you (or your vet) is giving these shots.

Whether you should give it or not has to be a personal decision, based on the benefits and risks, which are specific for your horse and area. EHV is particularly hard to evaluate as a flare of a old infection may play a role in abortion (see article on EHV for more on this).

If soreness is the only problem you are having predosing with bute then treating for 3 days post vaccination, will prevent it. This is covered in the article on vaccintation. If your horse stayed sore for 7 days you could treat that long.

Dr. O.,
I have only had the gelding actually "react" to it, and it may have been strangles, as the vet did both at the same time, so I'm not sure. All I know is he started shaking violently and went down and had a fever. After banamine, he got better within about 15 minutes, then was fine. I suppose it could have been colic, but it was too soon after the shots to have been, in my opinion. Anyway, the mare just gets really sore. So, I will make sure to bute her before and after. So, is EVH 1/4 flu rhino? I didn't see an answer to that. Which brand do you use? You also said you give pneumabort. Would this substitute for EVH 1/4 (ie flu/rhino) or in addition? So, since my gelding is stabled next to my mare, would it be bad to not give him the vaccine (even if she is vaccinated)?
Thanks,

The strangles injection has a much higher and more severe reaction rate than the other injections and so it is far more likely. If a horse had an immediate reaction following injection, that caused him to go down, this sounds like possible inadvertent intrarticular injection.

Rhino(pneumanitis) is caused by both EHV-1 and EHV-4. Abortion caused by herpes virus is usually EHV-1. Influenza is not related to these viruses, just causes respiratory disease. Different vaccines will have different mixtures of these. Alicia, this is all explained in greater detail in Care for Horses » Disease Prevention and Health Care » Vaccines and Vaccination Schedules » Equine Vaccines. Each disease has its own heading in this article.

The recommendations for vaccination of the pregnant mare is covered in » Equine Reproduction » Breeding and Foaling » Pregnant Mare Care and Nutrition. Look under the Vaccination heading in the article and it includes a discussion of products and schedules.
