Foal Care

Foal Vaccinations

Once your foal is born, immediate disease protection can occur through the consumption and absorption of his vaccinated dam’s first milk, called colostrum. Over time, the maternal antibodies present in the colostrum decline and your foal needs the added protection that only comes through proper immunization. Preventing disease through a strategic vaccination program is safer, easier and more economical than treating a sick foal.

Work with your veterinarian to develop a customized vaccination schedule that takes into account your region of the country, endemic diseases on your farm and your foal’s risk of disease exposure. Risk factors to consider include how many other mares and foals your foal will contact during the first year of life and whether your foal will remain on your farm or travel to other locations when his dam is rebred or he is sent for training.

Timing of the first vaccinations is critical. The maternally derived colostral antibodies that provide the foal with temporary protection are the same antibodies that prevent the foal from mounting an acceptable immune response to vaccines that are administered too early.

Around four to six months of age, your foal is ready for its first vaccinations (if its dam had been vaccinated). The following vaccination schedule is adapted from AAEP core and risk-based vaccination guidelines for foals.

Talk to your veterinarian about which risk-based vaccines are needed for your farm and geography. Specific vaccine product label recommendations may vary by manufacturer. Refer to the manufacturer’s product label.
