Adult Horses

The adult horse should be vaccinated annually (typically in the springtime) with the following vaccinations:

  1. EEE/WEE – Eastern Equine Encephalomyelitis and Western Equine Encephalomyelitis. In some regions, VEE (Venezuelan Equine Encephalomyelitis) may be indicated.
  2. Tetanus
  3. Rhinopneumonitis (EHV-1 and EHV-4) and Influenza
  4. West Nile virus
  5. Strangles
  6. Rabies

There is also a vaccination being developed for pigeon fever (aka dryland strangles)

In the performance horse that may travel frequently, rhinopneumonitis and influenza should be given every four months. This can be given either IM (intramuscular) or IN (intranasal). I prefer to give this via IN to lessen any side effects and, therefore, reduce the risk of an inconvenient time off.

As always, ask your veterinarian what vaccinations you need for the area you live in.
