1. Rehydrate 1 vial of vaccine with 1 vial of diluent.

2. Remove seal and stopper from vaccine and diluent vials. Avoid contamination of stoppers and contents.

3. Add diluent to half-fill the vaccine vial. Replace stopper and shake until contents are dissolved.

4. Pour the rehydrated vaccine into the diluent container. Replace stopper and shake.

5. Remove stopper and fit drop-dispenser tip into diluent container.

6. To vaccinate intranasally, place finger over one of the bird’s nostrils and place 1 drop of vaccine in the other nostril. Do not release bird until vaccine has been inhaled.

7. To vaccinate intraocularly, place 1 drop of vaccine in the eye.

For Drinking-water Vaccination

This vaccine is recommended for the vaccination of healthy chickens 2 weeks of age or older.

1. Discontinue use of medications or sanitizing agents in the drinking water for 24 hours before vaccinating. Do not resume use 24 hours following vaccination.

2. Water used for the drinking-water administration of a live virus vaccine must be non-chlorinated.

3. Provide enough waterers so two-thirds of the birds may drink at one time. Scrub waterers with fresh, clean, non-chlorinated water, and use no disinfectant. Let the waterers drain dry.

4. Turn off automatic waterers, so the only available water is the vaccine water. Do not give vaccine water through medication tanks.

5. Withhold water for 2 to 4 hours before vaccinating. Do not deprive the birds of water if the temperature is extremely high.

6. Remove seal from vaccine vial.

7. Remove stopper and half-fill vial with clean, cool, non-chlorinated water.

8. Replace stopper and shake until dissolved.

9. Use a clean container two-thirds filled with cool, clean, non-chlorinated water. Add dried milk at a rate of 1 ounce (28.4 grams) dried milk if final volume of water per 1,000 doses of vaccine is to be 2 1/2 gallons (9.5 liters); 2 ounces (56.8 grams) dried milk if final volume of water is to be 5 gallons (19.0 liters); and 4 ounces (113.6 grams) dried milk for a final volume of 10 gallons (38.0 liters). Stir the mixture until the dried milk is dissolved.

10. Add the rehydrated vaccine from the vial and again stir the contents thoroughly.

11. Next, add the mixture to the final volume of water, as follows:

Add this amount of vaccine

to this final volume of water

for chickens 2 to 8 weeks old

for chickens over 8 weeks old

1,000 doses

2-1/2 to 5 gallons
(9.5 to 19.0 liters)

5 to 10 gallons
(19.0 to 38.0 liters)

12. Give 1 dose of vaccine per bird.

13. Distribute the final volume of (vaccine) water evenly among the clean waterers. Do not place the waterers in direct sunlight. Resume regular water administration only after all the vaccine water has been consumed.

Revaccination

For growing chickens intended for replacement flocks or breeder flocks, it is advisable to revaccinate in advance of the onset of egg production.

Precautions

If possible, vaccinate all susceptible birds on the premises at the same time. For 10 to 14 days after vaccinating, avoid carrying vaccine particles on shoes, clothing, etc., into areas where there are unvaccinated birds.

Newcastle Disease Vaccine virus is capable of causing a mild, irritating eye infection in humans, lasting about 3 days. Do not allow vaccine to contact the eyes.
