I've been trying to post all of my vaccination questions in their appropriate places, so please bear with me.

My pregnant mare is going to be going into her 7th month in mid-february, and we will be giving our shots then. Should I postpone this until mid -May so it is closer to her pregnancy, or should I give her the shots now, and again in mid May. Also, i'm not sure if her starter shots were done properly in the correct timing sequence because I did not own her at that time. I feel like I should do all the initial vaccinations again just to be safe, but at the same time I'm not sure if it would be safe to do at this time. But at the same time - if it wasn't done correctly, then do I need to worry that the baby won't be getting enough of the maternal antibodies from her mom?

So if you could advise me on whether I should do the vaccines now or wait, and if I should do the initial series now or wait, I would greatly appreciate it. Thanks!

Rather than spreading around a lot of related questions Prakash, better would have been to put them all together. As long as you don't post questions about your horses in someone else's discussion we are not fastidious about where you post though we prefer some attempt at making it topic related.

Follow our recommendations in the vaccine schedule article as close as practical and don't worry if it is not perfect. If you suspect the initial vaccines were not done properly you should request the previous veterinarians records. Often these are not available and you must decide whether or not to trust the person you purchased the horse from. If you decide you do not trust them I would consider doing the original series based on the risk of the specific disease in the area, your veterinarian can help you with this.

I will keep that in mind next time I post something like this.

I don't trust the original owners, so I would like to do the original series - my main concern is would it be alright to do the original series while my horse is pregnant? And if it is, should I wait and time it so that they get the last dose one month before she is due to DrOp, or should I do the original series now and in 4 months give her all of her shots again before the baby is born?

If I were vaccinating a horse that I believed had not had the original series I would give it then booster one month before birth.

Alright, so i'm just going to run it by you what I plan to do just to make sure i'm not misunderstanding you - because I do value your opinion greatly.

I am going to vaccinate my mare who will be 6 and a half months along in her pregnancy at the time.

She will get the:
Rabies
WN
EWT
Rhino/Flu combo

Then a month later - when she is 7 and a half months a long, she will get:
WN
EWT
Rhino/Flu combo

And then a month laster when she is 8 and a half-i am going to give her a third dose of rhino/flu combo like the instructions say. I use the calvenza which says to use three initial doses. Is anyone familiar with it? I use it instead of the fort dodge because IT says it protects against the A and A2 subtypes, while the fort dodge just says it protects against the A2 subtypes. I'm not sure how accurate that is, but if anyone can advise me otherwise i would appreciate it.

But anyways, then when she is 10 months along, I will give her to following:
WN
EWT
Rhino/Flu
and the Rabies again? (or should I wait on the rabies until the 10 months so it won't be given in such a small period of time?) I'm so worried about putting any kind of stress on the baby by giving all these shots.

Prakash, I may be out of line here, but concerned. I have always been told not to give a Rhino vaccine to pregnant mares unless it was pneumobort Rhino vaccine, as it could cause abortion in the mare. On the other hand I do give the Flu/Rhino (not the pnuemobort)vaccine in the month away from foaling shots. I am not sure why it is safe to give it then, unless it has to do with how far along the mare is.
DrO, am I correct?

That would be incorrect Chris, in fact some feel this may be the least effective vaccine for the problem nor do many of the other vaccines including at least one of the MLV vaccines, represent a risk. See the article on herpes virus abortion I reference above for more.

Yes they make just the EHV1/4 and I think it is called Equivac. I cannot approve a vaccine protocol for your horses Prakash all I can do is educate you about them and then you, best working with your veterinarian need to make the decisions. If your veterinarian feels the risk of disease from these organisms is greater than the risk of vaccine reaction I would vaccinate. If I felt the horse did not have a primary series I would go ahead and start it. In spite of the primary series being given if it is has more than 4 months since a vaccine was given before the expected birth date I would booster the vaccine one month prior to birth. Hmmm is there anything not covered here?

Thanks DrO, this is nice to know.
Prakash, apologies for the misinformation, best wishes for you and your mare and foal.
