The Vetera EWT + WNV vaccine is used as an aid in the prevention of diseases caused by Eastern and Western Encephalomyelitis, (EEE and WEE), tetanus, and West Nile Virus, incorporating the 2005 WNV horse isolate that protects against the strain most likely to infect horses today.
Vetera vaccines are formulated using a proprietary exclusive Ultrafil™ Purification Technology, which removes most of the extraneous proteins. This makes it possible to include more antigens in a 1-mL dose and enables the horse's immune system to focus more directly on the relevant antigens.
The Vetera EWT + WNV vaccine contains killed viruses and inactivated bacterin toxoid. The duration of immunity against West Nile Virus is at least 12 months. No reconstitution is necessary. For use in healthy horses as young as 4 months of age.
Shake well before use. Using aseptic technique, inoculate horses intramuscularly with a 1 mL dose. Administer a second 1 mL dose intramuscularly in 3-4 weeks using a different injection site. Revaccinate annually and prior to anticipated exposure with a single 1mL intramuscular dose.
Frequently Asked Questions
How should I store my vaccines once I receive them?
You should always store the vaccines that you buy in the refrigerator. For best results, do not take them out of the refrigerator until you are ready to administer them.
I'm having my vaccines shipped by 1-day air. What other steps can I take to make sure that they stay cold but do not freeze?
If you are not going to be at the delivery point, in the summer leave a cooler with ice packs outside the door with instructions for the delivery person to place the vaccines in the cooler. In the winter, a cooler may also be used to insulate the vaccine and prevent it from freezing. When you place your order, let the operator know you are doing this so we can also place instructions for the delivery person.
