Directions For Use

1. Use Zoetis Inc. diluent only. Store diluent at not over 27°C.

2. Rehydrate only 1 vial of vaccine with 1 bottle of diluent.

3. Remove the central tab of the aluminum seal of the vaccine vial, leaving the outer ring intact. Sanitize the rubber stopper with alcohol. Also, sanitize with alcohol the rubber stopper of the container of diluent.

4. Using a sterile syringe and needle, penetrate the stopper of the diluent container and withdraw 3 mL diluent. Then, insert needle through stopper of vaccine vial and discharge syringe contents.

5. Remove syringe and needle. Pull back on syringe plunger to admit 2 or 3 mL of air. This is very important.

6. Reinsert needle into vaccine vial. Barely penetrate the stopper. Expel the air into the vial (to break vacuum).

7. With syringe and needle still in place, invert the vial and pull back plunger so that all the contents (the rehydrated vaccine) are drawn from vial into syringe.

8. Insert the needle into diluent container (through the stopper) and expel syringe contents into diluent. Rotate container gently so that mixture is uniform. The vaccine is ready for use.

9. An automatic syringe with 22- to 20-gauge needles, 3/8 inch to 1/2 inch in length, is recommended. Make certain that all equipment is sterilized. Change needles frequently.

10. Inject each bird subcutaneously in the back of the neck with 0.2 mL of the vaccine.

11. Use all vaccine from 1 vial (1,000 doses) within 1 hour after rehydrating. Avoid placing the vaccine near heat. Do not expose to direct sunlight.
