RECOMBITEK

Disease prevention starts with vaccination.

There are three good reasons for vaccinating horses:

  • Vaccination may be the only way to help protect horses from some diseases.
  • Preventing disease through vaccination causes less stress than recovery from infection.
  • Many diseases cause permanent damage or death.

Understand which diseases pose the greatest risk.

Currently, five diseases account for the core vaccinations recommended annually by the American Association of Equine Practitioners (AAEP):1 Click on any disease to learn more.

West Nile Virus Eastern equine encephalitis
Western equine encephalitis Tetanus Rabies

There is a difference between vaccines.

Today, innovative vaccines can use technology that helps them target only the parts of a virus needed for an immune response. Some vaccines also stimulate more than one arm of the immune system to protect the horse.

RECOMBITEK® Brand Equine Vaccines use recombinant canarypox-vectored vaccine technology that gives horses both of these advantages while helping protect against either WNV or equine influenza.
