Pregnant mares, inject one 1 mL dose intramuscularly at the eighth month of pregnancy using aseptic technique. Administer a second 1 mL dose one month later (i.e., at the ninth month of pregnancy). A third 1 mL dose is then given one month later (i.e., at the tenth month of pregnancy). Each pregnancy requires vaccination with 3 doses.
Equine rotavirus is highly contagious and thought to infect around 50% of foals if the disease is present in their area. Unlike the canine rotavirus which can be transmitted to humans, the equine rotavirus is species specific and known to only affect young foals. Currently, death is not very common following infection from this disease with the exception of very severe cases.
The milder form of the disease presents itself with the foal having soft feces. This usually occurs in this form if the foals are approximately two months of age. As it damages the intestinal lining, the equine rotavirus reduces the ability for the cells to absorb water and other materials. The disease can progress in this way so that the young foal
experiences runny, water-like diarrhea. This can result in dehydration and the foal will become depressed following infection of the equine rotavirus.
