As FEIF did receive some questions about the rules about equine influenza vaccinations the document describing the demands has been updated. For horses competing all year around (or taking part in breeding shows and other events), 2 vaccinations per year are required in a correct interval. For horses taking part in events for a period shorter then 6 months per year, 1 vaccination per year is sufficient, provided that the vaccination started and was maintained in a correct way. In all cases the last booster must have been given within 6 calendar months + 21 days of the start of the any event.
