Is there a vaccine for West Nile virus?
There is no licensed vaccine available for humans. The National Institute of Allergy and Infectious Disease in the United States is using a private company to test a prototype vaccine. The vaccine has shown promise in animal tests. Human tests are anticipated some time this year. Health Canada is monitoring the situation carefully. Keep in mind that a vaccine licensed in the United States is not automatically licensed in Canada. There are two West Nile virus vaccines in Canada registered for use in horses only.
There is no vaccine to protect humans against West Nile virus infection. In August 2001 a vaccine to help protect horses against West Nile virus infection was conditionally approved by the U. S. Department of Agriculture. Please contact your veterinarian for information about obtaining the vaccine for your horse.
