The company says that so far, it has had no cases of flu reported in horses vaccinated with Equip F or Equip FT in the UK. However, it cautions that in the present flu outbreak it is not clear if any of the current influenza vaccines will provide complete clinical protection against the mutated strain.

In addition, Zoetis highlights that: 

  • Equip F and Equip FT are both indicated for reduction in clinical signs caused by Equine Influenza, including Florida Clade 1 strains.

  • Cross protection has been demonstrated by virulent challenge for representative strains of Florida Clade 1 (Paillot et al 20081, Bryant et al 20102) and Clade 2 (Paillot et al 20153).

  • Vaccination with Equip F stimulated a flu specific cell-mediated immune response to a Clade 1 strain which was detectable for up to one year after the third vaccination in primary course (Paillot et al 20153).

Zoetis says it is confident that the Equip range continues to be effective against its licensed indications.
