There are THREE primary flu vaccinations before annual boosters:
1st PRIMARY vaccination must be given
2nd PRIMARY vaccination between 21 and 92 days after 1st primary vaccination
3rd PRIMARY vaccination between 150 and 215 days after 2nd primary vaccination
Further booster vaccinations at intervals of not more than a year apart (or such lesser time as the Authority may, in an emergency, decide)

REMEMBER – The first two vaccinations must be given BEFORE a horse can be taken to a racetrack
REMEMBER – None of the vaccinations must have been given on the day of a race in which the horse is declared to run or on any of the six days before the race
REMEMBER – To COMPLETE the programme by having the third vaccination
REMEMBER – The current Owner/Trainer of the horse is responsible for ensuring the FLU VAC RECORD is correct NOT the BHRC
