VACCINATION SCHEDULE Basic vaccination course

All horses not previously vaccinated should receive 2 vaccinations of 1 dose with a 4-week interval. The basic vaccination course results in immunity to equine influenza lasting at least 5 months. Foals should be vaccinated from the age of 6 months. If vaccination is performed before 6 months of age full protection can be expected after the third vaccination (first revaccination).


The first revaccination (third dose) is given 5 months after the basic vaccination course. The revaccination with Equilis® Prequenza or Equilis® Prequenza Te results in immunity to equine influenza for at least 12 months.

The second revaccination is given 12 months after the first revaccination.

The alternate use, at 12-month intervals, of Equilis® Prequenza is recommended to maintain immunity levels for the influenza component.

Local Regulations

Although Equilis® Prequenza and Equilis® Prequenza Te results in immunity for 12 months, local Jockey Club and Horse Society regulations should be adhered to. These often recommend a 6-month vaccine interval. In this case the alternate use of Equilis® Prequenza and Equilis® Prequenza Te is recommended.


Can be used in pregnant mares, but handling of such animals, particularly in the latter stage of pregnancy, is not without risk and care should be taken to avoid stress.
