Horse 5-Way Vaccine Planner
Interactive planner that personalizes 5-way horse vaccine timing by age, use, region, last dose, with West Nile reminders, broodmare windows, and foal series dates.
Frequently Asked Questions
What does a 5-way horse vaccine cover?
It combines protection against Eastern & Western Equine Encephalomyelitis (EEE/WEE), tetanus, equine influenza (flu), and equine herpesvirus (EHV-1/4). It’s one IM shot instead of five separate injections.
Does a standard 5-way include West Nile Virus (WNV)?
Usually no. Most 5-ways cover EEE, WEE, tetanus, flu, and EHV-1/4. Add a separate WNV vaccine each spring or use a labeled combo that explicitly includes WNV.
How often should I vaccinate an adult horse at home (low exposure)?
Typically once per year, timed before mosquito season—spring in most regions. Confirm timing with your veterinarian for your climate and barn risk.
How often for show, lesson, or traveling horses?
Every 6 months (spring and fall) because of higher flu/EHV exposure and venue requirements. Many events require proof of flu/EHV within 6 months (±21 days).
When should I vaccinate in Northern vs Southern climates?
Aim just before mosquitoes: Apr–May in northern/temperate regions; Feb–Mar in warmer southern regions. Fall boosters for show horses are ~6 months after spring.
What’s the tetanus ‘wound booster’ rule?
If your horse has a deep/puncture wound and it’s been more than ~6 months since the last tetanus shot, call your veterinarian—an immediate booster is often advised.
Are 5-way vaccines safe for pregnant mares?
Use pregnancy-approved products on a vet-timed schedule. A common booster window is 4–6 weeks before foaling to enhance colostral antibodies.
When do foals start their 5-way series?
Dam vaccinated: start at ~4–6 months (2 doses 3–4 weeks apart) with a booster near 12 months. Dam unvaccinated: may start around 3 months with a vet-directed series.
My horse missed last year—do I restart the series?
If it’s been >12 months since the last booster, many vets restart with two doses 3–4 weeks apart to rebuild protection. Follow your veterinarian’s protocol.
What reactions should I expect and when do I call the vet?
Mild swelling/soreness and a low-grade fever (<102°F) can occur and resolve within 24–48 hours. Call your vet for fever >103°F, hives, breathing difficulty, severe swelling/abscess, or lameness.
Can I give the vaccine myself and how should I store it?
Many owners self-administer intramuscularly, but technique, product choice, and timing should be vetted. Maintain the cold chain (avoid heat/freezing), use clean technique (needle first, aspirate, inject slowly), and follow the label.
How much does a 5-way cost and what records should I keep?
The vaccine dose is commonly about $25–$50; a vet visit costs more but includes an exam and monitoring. Record product, lot, expiry, date, injection site, and administrator; keep proof for shows and barn logs.
