Frequently Asked Questions
What are the current BHA vaccination rules?
For courses started in 2022 or later:
- V1 to V2: Must be 21-60 days apart
- V2 to V3: Must be 120-180 days apart
- Subsequent boosters: Every 6 calendar months
For courses started before 2022:
- V1 to V2: Must be 21-90 days apart
- V2 to V3: Must be 150-215 days apart
- Subsequent boosters: Every 12 months
What happens if my horse missed a booster?
If a booster is overdue, the vaccination schedule is no longer compliant. You'll need to contact your vet to restart the primary vaccination course. The calculator will identify if any boosters are overdue and when the next one should be administered.
Can my horse compete if the booster is overdue?
No. A horse cannot compete at BHA-licensed premises if their vaccination schedule is not compliant. All vaccinations must be up-to-date and within the required intervals. If your horse's vaccinations have lapsed, you must restart the primary course before competing.
What if the course started in 2021?
If your horse's primary vaccination course (V1 and V2) started in 2021, select "Before 2022 (Old Rules)". The old rules apply: V1-V2 interval of 21-90 days, V2-V3 interval of 150-215 days, and annual boosters (every 12 months).
How far in advance should I book booster vaccinations?
It's recommended to book booster vaccinations at least 2-4 weeks before the due date to ensure compliance. This provides a buffer in case of scheduling conflicts or if your vet is unavailable. The calculator shows your next due date to help you plan ahead.
Do I need to enter all vaccination dates?
You must enter V1 (first vaccination) and V2 (second vaccination) dates. V3 and last booster dates are optional but recommended for accurate compliance checking. If you only have V1 and V2, the calculator will tell you when V3 is due.
