Assuming that you haven’t been living in a cave, or haven’t been enjoying some wonderful vacation in a remote location without internet access (they exist), by now, you’ve probably heard of EHV-1,. NOTES: Only in eastern half of US. I have been told she needs the first at 5 months, then 7, then 9. The toxin produced by the bacteria produces painful muscle spasms that can be severe enough to cause convulsions. Encephalomyelitis (Sleeping Sickness) This viral, mosquito borne disease affects the nervous system of your horse (and rarely humans). It also appears very likely that once a horse has been infected with either EHV-1 or -4, it will persist within the horse without clinical signs until there is a period of stress or immunosuppression. For this reason, we recommend boosting the immunity of the pregnant mare 6-8 weeks before foaling.
Intended to promote proper vaccination protocols, this rule does not anticipate an increased workload for competition management. It causes the animals muscles to contract until it is unable to breath; an extremely unpleasant death. For immunizations to be effective, the recipient must be healthy. This pilot study demonstrates the immunogenicity of recombinant MVA vectored AHSV vaccines, in particular MVAVP2, and indicates that further work to investigate whether these vaccines would confer protection from lethal AHSV challenge in the horse is justifiable. 18. Secondly, as for the ‘combination’ vaccines, in general more in one is not better. They are sort of like the quiet family that lives in the dark house down the street, or in the apartment down the hall.
Certain vaccines obtain a better response via a certain route. For a little extra cost it is worth it! Some horses can recover from the neurological form of the disease, but unfortunately some do not and have to be put down. It is highly contagious with the virus having the ability to be transmitted over distances of thirty yards by way of snorting or coughing. Isolation of both affected horses and new arrivals to ensure they are not incubating disease; segregation of high-risk horses (pregnant mares from weanlings or yearlings, for instance); keeping horses in smaller groups and, where possible, moderating or minimizing stress factors. The species of mosquito most prevalent in early spring and summer is not very efficient in transferring the diseases, but another species that comes on late in the summer is. The type (based on ‘active ingredient) should be rotated.
These shots can be combined with tetanus vaccination to reduce the number of vet visits and injections.
