EIA VACCINE
A vaccine that prevents equine infectious anemia (EIA), the disease detected
by the Coggins test, may soon be available.
The University of Pittsburgh and the University
of Kentucky Gluck Equine Research Center published test results in the 2003
Journal of Virology.
A vaccination with a genetically modified strain of EIA virus, which has
limited ability to reproduce in the horse’s body, provided 100% protection in
challenge studies, compared with 100% induction of the disease in identically
exposed unvaccinated controls. Previous vaccines were either
limited in protection or actually worsened the disease.
