West Nile Virus Equine Vaccines in Orange County

West Nile Virus causes a neurological disease in horses and to a lesser extent in humans and other animals. The reservoir host for the virus is birds, most often crows and ravens in Southern California. It is spread by mosquitoes which transmit the virus from the birds to other animals when they bite.

 

When the West Nile Virus first emerged in North America several years ago, there were horses still developing the disease who had been receiving the vaccination. For that reason, it is suggested that all horses be vaccinated every six months for West Nile Virus at this time. There are several manufacturers of West Nile vaccine. Some products are far superior to others. Be sure to ask your EVA veterinarian for more clarification if you are interested.
