The following are considered general guidelines for vaccination. It is still important to consult with your veterinarian to determine the vaccine protocol that works best for you and your horse's individual situation. 

Core Vaccines
 Schedule *
 Mode of Transmission
 Eastern Encephalitis
 More common in the East, this disease can be devastating if horse is infected. Can cause severe neurological conditions
 Western Encephalitis
 Similar to EEE, but appears more in the West. Also causes neurological symptoms. While there is a low rate of occurrence, many birds and mosquitos still test positive.
 wound contamination from environment
Found everywhere in the soil, can cause severe neurological disease. Causes a paralysis that does not allow the muscle to relax. 
 1-2 x annually based on exposure
 horse to horse contact
 Primarily a respiratory disease spread easily from horse to horse, and also through items that infected horses touch (buckets, etc.)
 1-2 x annually
 horse to horse contact
 Primarily a respiratory disease, occasionally can become neurologic. Spread amongst horses and items they touch (buckets, etc.). Variant can cause abortion in horses.
 West Nile Virus
 Prevalent throughout the United States. Infected horse will show neurological symptoms that may last for 6 months post infection.
 Annually up to 8-9 yrs of age
 horse to horse contact
 Caused by Streptococcus Equi Equi. Will see high fevers and often respiratory symptoms. Lymph nodes under jaws may become very large. Spread easily from horse to horse. More common in the younger populations.
 Annually (especially in areas of high exposure
 saliva of infected animal
 Transmissible to humans. Although prevalence is low, due to the fatal nature of the disease, vaccination is highly recommended.

* All vaccinations should get an initial dose and booster 3-4 weeks later (except for rabies). Initial series should not be started prior to 6 months of age due to maternal antibodies having the potential to interfere.

The following is a list of dewormers that are commonly used to manage Equine parasites.

An initial consult may include fecal egg counts to get an idea of parasite load in the horse.
