Tenosynovitis Vaccine

Modified Live Virus

For Veterinary Use Only

Read in full, follow directions carefully.

V.A.-Vac is recommended for the subcutaneous injection of healthy breeder types of chickens 3 to 18 weeks of age, as an aid in the prevention of tenosynovitis (viral arthritis) in the vaccinates and in offspring chickens.

Store this vaccine at not over 7°C (45°F).

Do not vaccinate within 21 days before slaughter.

Use entire contents of vial when first opened.

Burn vaccine container and all unused contents.

V.A.-Vac Caution

Use only in areas where permitted.

Directions For Use

1. Rehydrate 1 vial of vaccine with 1 vial of diluent (as described below).

2. Use Fort Dodge Animal Health diluent only. Store diluent at not over 27°C (80°F). The exact quantity of diluent is provided for each shipment of the vaccine.

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 diluent bottle. Allow stoppers to dry thoroughly.

4. Using a sterile syringe and needle, penetrate the stopper of the diluent bottle and withdraw 3.5 mL (3.5 cc) of diluent. Then, insert the needle through the stopper of the vaccine vial and discharge syringe contents. Remove needle and syringe.

5. Vigorously shake the vaccine vial to dissolve the vaccine completely.

6. Pull back on the syringe plunger to admit 2 or 3 mL of air. This is very important.

7. Now, reinsert needle into vaccine vial. Barely penetrate the stopper. Expel the air into the vial (to break vacuum).

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

9. Now, insert the needle into the diluent bottle (through the stopper) and expel the contents into diluent.

10. Shake the bottle to ensure a uniform mixture.

11. Begin vaccination immediately.

12. For the vaccination, an automatic syringe with 22- to 20-gauge needles, 1/2 to 3/4 inch in length, is recommended. Make certain that all equipment is sterilized and change needles frequently.

13. Inject each bird subcutaneously in the back of the neck with 0.2 mL (two-tenths of a milliliter) of the vaccine.

14. Use all of the vaccine from 1 vial (1,000 doses) within 1 hour after rehydrating. Avoid placing the vaccine near heat or in the direct sunlight while vaccinating. Do not save any vaccine that has been rehydrated and not used. Burn all unused opened material.
