| Tetanus |
Initial dose with booster in
3-4 weeks, Annual booster. |
Local tissue reaction; anaphylaxis in some horses. |
| Tetanus Antitoxin |
Use in non-immunized
horses or horses of unknown history at time of injury. |
Protection for only 7-14 days. |
| Botulism |
Before exposure in endemic areas. |
Local tissue reaction; anaphylaxis in some horses. |
Encephalomyelitis
(Eastern, Western, Venezuelan) |
Initial dose with booster
in 3-4 weeks. Annual to
biannual booster. |
Do not stress horses recently vaccinated from Venezuelan encephalomyelitis. |
| Rabies |
Horses must be older than 3 months of age. Annual booster. |
Possible local tissue reaction if injected subcutaneously. |
| Influenza |
Initial dose with booster in 3-4 weeks. Biannual for low to moderate risk horses. Every 2-3 months for high risk horses. |
Do not vaccinate 2-3 weeks
before a stressful event. Some horses experience a brief fever,
loss of appetite, and depression after vaccination. |
| Potomac Horse Fever |
Initial dose with booster in 3-4 weeks. Revaccinate every 4-6 months in endemic areas, otherwise annually. |
Local tissue reation. |
| Strangles |
Initial dose with 1 to 2 boosters 2-4 weeks later. Annual booster. |
Biannual vaccination of young horses at risk may result in anaphylaxis. Postvaccinal reactions include treatable abscesses at site of injection. Vaccination does not always prevent infection
and clinical signs. |
Rhinopneumonitis
(EHV-1 & WHV-4) |
Initial dose with booster in 4-6 weeks. Annual booster. |
Deep intramuscular injection in hind leg. Use a vaccine that contains EHV-1 & EHV-4 strains. Mild exercise to promote absorbtion is recommended for
1 week after injection. |
| Anthrax |
Initial dose with booster in 2-3 weeks and 2-4 weeks before an expected anthrax exposure. Annual booster. |
Do not vaccine horses undergoing antibiotic therapy. Local tissue reaction expected. Placing horse in dark stall for 10 days may be beneficial. Not a routine vaccination. Burn container and any unused vaccine. |
| Equine Viral Arteritis |
Vaccinate at any time, except foals younger than 6 weeks of age and stallions 3 weeks before breeding. Vaccinate open or maiden mares but at least
3 weeks before breading. |
