Equine herpesvirus (EHV) is a contagious virus affecting horses, causing respiratory illness, neurological disease, and reproductive issues. Understanding the vaccination schedule for equine herpesvirus is essential for horse owners to protect their equine companions. This guide provides a comprehensive overview of the vaccination protocol, ensuring your horse remains healthy and protected.
What is the Recommended Vaccination Schedule for Equine Herpesvirus?
The recommended vaccination schedule for equine herpesvirus typically involves initial doses followed by regular boosters. Generally, horses should receive a primary series of two doses, 4–6 weeks apart, followed by booster vaccinations every 6 months. This schedule helps maintain immunity and reduce the risk of EHV outbreaks.
Why is Equine Herpesvirus Vaccination Important?
Vaccination against equine herpesvirus is crucial because:
- Prevents Disease Spread: Reduces the likelihood of EHV outbreaks in equine communities.
- Protects Horse Health: Minimizes the risk of respiratory and neurological symptoms.
- Supports Reproductive Success: Decreases the incidence of abortion in pregnant mares due to EHV.
How Does the Equine Herpesvirus Vaccine Work?
The equine herpesvirus vaccine stimulates the horse’s immune system to recognize and combat the virus. By introducing a small, harmless component of the virus, the vaccine prepares the horse’s immune system to respond effectively if exposed to the actual virus.
What are the Different Types of Equine Herpesvirus Vaccines?
There are several types of equine herpesvirus vaccines available, each with specific benefits:
| Vaccine Type | Description | Frequency |
|---|---|---|
| Inactivated (Killed) | Contains inactivated virus particles | Every 6 months |
| Modified Live | Contains weakened live virus | Every 6 months |
| Combination | Protects against multiple strains (EHV-1, EHV-4) | Every 6 months |
When Should Foals Receive Their First Equine Herpesvirus Vaccine?
Foals should receive their first equine herpesvirus vaccine at 4-6 months of age. This timing allows maternal antibodies to wane, making the vaccine more effective. A second dose is administered 4–6 weeks after the initial vaccination, followed by regular boosters every 6 months.
How Should Pregnant Mares Be Vaccinated?
Vaccination of pregnant mares is essential to prevent abortion due to EHV. The recommended schedule is as follows:
- 5th, 7th, and 9th month of pregnancy: Administer EHV vaccinations to protect the mare and the developing fetus.
What are the Potential Side Effects of the Equine Herpesvirus Vaccine?
While the equine herpesvirus vaccine is generally safe, some horses may experience mild side effects, such as:
- Swelling at the injection site
- Mild fever
- Lethargy
These side effects are typically short-lived and resolve without intervention. Always consult with a veterinarian if you have concerns about your horse’s reaction to a vaccine.
How Can You Ensure Effective Vaccination?
To ensure effective vaccination, consider the following tips:
- Consult with a Veterinarian: Tailor the vaccination schedule to your horse’s specific needs.
- Maintain a Record: Keep detailed records of all vaccinations and booster shots.
- Monitor Health: Observe your horse for any adverse reactions post-vaccination.

How Long Does Immunity Last After Equine Herpesvirus Vaccination?
Immunity from the equine herpesvirus vaccine typically lasts about 6 months, necessitating regular booster shots to maintain effective protection.
Can Horses Still Get EHV After Vaccination?
While vaccination significantly reduces the risk of EHV, no vaccine offers 100% protection. Vaccinated horses may experience milder symptoms if they contract the virus.
Are There Any Alternatives to Vaccination for EHV Prevention?
In addition to vaccination, biosecurity measures such as quarantine, hygiene practices, and minimizing contact with unknown horses can help prevent EHV spread.
What Should I Do If My Horse Misses a Scheduled Booster?
If your horse misses a booster, consult your veterinarian to determine the best course of action. They may recommend restarting the vaccination series to ensure adequate immunity.
Is EHV Vaccination Mandatory for All Horses?
EHV vaccination is not universally mandatory but is highly recommended, especially for horses in high-risk environments like breeding facilities and competitive events.
Conclusion
Vaccinating against equine herpesvirus is a critical component of maintaining your horse’s health and preventing disease outbreaks. By following the recommended vaccination schedule and consulting with a veterinarian, horse owners can ensure their equine companions are well-protected.
