Vaccinate llamas/alpacas annually with CD/T, a clostridium/tetanus immunization. Administered SQ, consult your vet for the proper dosage. A 7-Way or 8-Way is also a suitable vaccination, but some breeders feel the CD/T is enough. A good time for vaccinating is in the spring before the weather gets hot. Do not vaccinate any pregnant females within 60 days of birthing or within 60 days after breeding. Another booster vaccination should also be given to an expectant mother about 60 days prior to the delivery date to increase the antibodies in the colostrum. Vaccinate crias with CD/T at 10-12 weeks of age. Give a booster of CD/T again 4 weeks later. Crias do not need to be vaccinated at birth.
