Frequently Asked Questions (FAQs)

When is the best time to vaccinate a new born foal? I read that the anti-bodies the foal receives from the mare, will only last 3 weeks and that the foal only starts building its own antibodies by the age of 3 months?

  1. If the mare was vaccinated prior to the foaling, do not vaccinate the foal under 4 months of age.
  2. Antibodies in foals from vaccinated mares wane between 4-6 months.
  3. If the mare was not vaccinated, then you can vaccinate the foal from 3 months of age and repeat 6 months later.
  4. The foals own immune process does not function under 3 months.
  5. As you are entering AHS time, take all precautions with repellants etc.
