Foal to Yearling Vaccination Protocol

If the foal's mother was vaccinated 30-45 days before foaling, a tetanus vaccination for the foal is not absolutely necessary. However, it is advisable to give them a tetanus booster shortly after birth. Other vaccinations are not needed until the foal is approximately 6 months old (use the following program times). If the mare was not vaccinated 30-45 days prior to foaling, the the foal needs a tetanus after birth plus the other vaccinations are needed at approximately 4 months of age (two months earlier than the following program times). We also recommend a neonate physical examination of all foals when they are 24-36 hours old. This may include drawing a blood sample fo an IgG test (to make sure the foal received enough antibodies from the colostrum) and a complete blood count, depending on how the pregnancy and foaling went.

Vaccination First Second
EHV1/4 (Rhinopneumonitis) 6 months 7 months
Influenza 9 months (Intranasal)  
Eastern, Western, and Tetanus 6 months 7 months
Rabies 6 months 7 months
Potomac Horse Fever 6 months 7 months
West Nile 6 months 7 months

For high risk farms ( a lot of horse movement on and off the farm), intranasal flu is recommended at 6 month intervals or injectable flu should be boostered at 3 to 4 month intervals until 2 years old and then boostered at 4 to 6 months intervals after that.

EWT (Eastern, Western Encephalomyelitis and tetanus), West Nile, and Rabies should be boostered annually after the horse becomes a yearling. Potomoc Horse Fever should be boostered semi-annually.
