Vaccine Rule Changes

Equine Flu Vaccination Rule Changes for 2024

From 1st January 2024 vaccination rules for Equine Flu have changed for many of the equestrian disciplines in accordance with advice from the British Equestrian Federation (BEF).

Vaccination intervals after 1st January have reduced date ranges between the first two vaccinations in a primary course and the first booster. Any horse restarting flu vaccinations or receiving a new primary course from 1st January will be affected by the changes. Vaccinations that are up-to-date and correct will not be affected.

Competition horse owners should ensure that their horse or pony is vaccinated for Equine Flu in accordance with the rules of the appropriate sporting governing bodies under which they are competing (e.g. FEI, British Eventing, British Dressage, British Showjumping, The Pony Club, British Riding Clubs, etc).

Equine Flu vaccination Intervals for many governing bodies from 1st January 2024 are as follows*:

  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)


*Please note: VACCINATION RULES DIFFER BETWEEN ORGANISATIONS. It is your responsibility to check the requirements of your particular discipline before starting a course of vaccinations.

Polo Vaccinations- Update for 2022

Current vaccination regulations relating to Equine Influenza can be found at All ponies must be compliant to be allowed onto HPA-affiliated premises, so it’s worth taking the time to check! In brief, all ponies (and Umpire ponies) may play after a primary course (first and second dose 21-92 days (3 weeks-3 months) apart). This should then be followed by a first booster at 150-215 days (5-7 months) and subsequent boosters within 1 calendar year of the last dose; or, if the previous booster was given in March/April, then within this window. IN ADDITION, ponies must have received a vaccine dose (2nd dose of primary course or a booster) within the previous 6 months +21 days to attend HPA-affiliated premises. Ponies that have fallen outside this window (but still within the primary course + booster criteria) are eligible to play 2 days after receiving a vaccine dose.
