Potomavac PHF

POTOMAVAC helps deliver proven protection from Potomac horse fever.

POTOMAVAC helps deliver proven protection from Potomac horse fever.

  • You can safely use POTOMAVAC in horses as young as 3 months of age.1
  • For unvaccinated horses, a primary two-dose vaccination is required with a single-dose booster each year.1
POTOMAVAC Usage
Dose Age Administration Desiccant (cake) Diluent (liquid) Package
1 mL
annual*
3 months
and older
Intramuscular (IM) No desiccant Ehrlichia risticii
bacterin — killed
5 x 1 dose
3 x 10 dose
*For previously vaccinated horses. Unvaccinated horses require a primary two-dose vaccination, three to four weeks apart.1

The goal of an immunization program should be to time vaccination(s) so the horse has the highest level of immunity before and during highest exposure to disease. For Potomac horse fever (PHF), this is just before peak insect hatch — usually mid- to late summer into early fall.1

Use POTOMAVAC + IMRAB® to help protect against rabies in the same dose.

The benefits of POTOMAVAC are available in a convenient combination vaccine that also includes IMRAB® rabies vaccine.

This lets you add protection for horses against rabies, one of the five core vaccinations recommended annually by the American Association of Equine Practitioners (AAEP).2
