Days between initial first, second and third vaccines

[holeymoley]

I think I butted into someone else's thread last week querying this and I only got 1 or 2 answers.

Can anyone shed light on the current, most up to date advice and timeframe for giving initial vaccines?

I'm in between dose 2 and 3 at the moment but finding some conflicting information. Vet receptionist/practice is advising not before 150 days for 3rd vaccine. However, anything searched on google states that any vaccines started after January 2024, should be not before 120 days for 3rd vaccine. I suppose at the end of the day it's trivial, my older guy needs his booster in August and I was hoping I could tie in and get the youngster's done too, that way it's all done together (less chance of me forgetting another date!) If it's not before 120 days, they can easily get done at the same time. If it's not before 150 days then youngster will need to wait until October I think.

I've sent the below information to vets but they're still insisting it's not before 150 days.... what's going on?!

Equine Influenza (Flu)

	Intervals before 1 January 2024	Intervals from 1st January 2024
1st Vaccination (V1)
2nd Vaccination (V2)	21-92	21-60 days
3rd Vaccination (V3)	150-215 days	120-180 days
Booster	Within 6 months or 12 months (depending on governing body)	Within 6 months or 12 months (depending on governing body)

It's probably because the table you have shown is from the competition rules side of things, but the data sheets for the vaccines all state 5 months( ie 150 days)...so the vets are doing things correctly as per the data sheets!

I had no idea the initial periods were different, thought it was just the annual/6 monthly ones!

I take it when you mean 'competition' this is FEI level, or maybe racing, at which point I as a mere mortal dont have to worry about it?!

Ive got a horse just had the 1st vac, and stretching the list of the pre 2024 shedule i can tie him in with my other horse. If not will be quite annoying!

But surely they should all be singing from same hymn sheet. What if it wasn't a youngster I was vaccinating but say, an 8 year old sports horse that had lapsed and I wanted to compete in area qualifiers with the riding club. Once the vaccine 1 and 2 are given, I'd need to get the 3rd one done 120-180 days, potentially if the vet goes by their data sheets then you could be 'out' by 35 days if it goes over.

Just trying to get my head round it, it all seems a bit complicated. It used to be 1st one, then 2nd one within 6 weeks then 3rd one within 6 months then annual. But that was 20 odd years ago. It was probably more specific with days but never seemed to be as complicated as it is now. Or maybe I'm getting a bit thicker in old age

If you are competing and your horse started their vaccination course before Jan 2024 then as long as the time periods match the table on the left and you have your annual boosters in time then okay to compete.

If you start a new vaccine course after Jan 2024 then it must follow the time periods on the right to compete regardless of age of horse.

If pre 2024 you follow the time periods on the right than that is also allowed for competing.

That ^ is my understanding of it. My youngster had first vaccine in March 24 and send last week. I would expect him to follow the right column, as surely in the future he may compete?

It is any competition or show venue that requires the horses to be vaccinated....so all affiliated competitions plus ( in theory) those run under affiliated rules, also PC/RC etc.

No....the intervals are consecutive eg :

1st vacc : day1
2nd vacc : day 21-60
3rd vacc : 120-180 days after the 2nd vacc ( so 150 days is slap bang in the middle.)

The data sheets give the advised intervals for the best immune response, but the competition guidelines allow for some leeway from exactly 150 days!

Yes they have to if you want to compete.

 

[piglet2001]

Our vets are recommending

V1-V2 21-60 days
V2-V3 150-180 days

If you have it done at 120 days then for some governing bodies you will be too early and therefore not meet their vaccination requirements. By waiting until 150 you will satisfy all governing bodies.

If you are ‘just’ competing under one governing body you can just follow their requirements, but bear in mind that if you decide to compete under another in the future or you sell/loan your horse and the new rider wishes to then the vaccinations will potentially have to be restarted if they are done before 150 days.

Hope this helps.

Spot on.
I have double checked this with BRC and yes, that's right.
I've followed this up again last week with my vet practice (for personal interest) and they prefer (for 2024 starters or restarters) to give jab 3 150 to 180 days, for full vaccine efficacy, but will follow the 2024 guidelines if client requests this.

That makes sense. I've just had my companion/loaner's jabs re done as they had lapsed while away. When I rang for his 3rd jab I thought he would need it before the end of march but I wasn't able to book it until the first week in April at the earliest. I'm usually good with dates but it through me a bit.
