3. Provide sufficient waterers so that all of the birds can drink at one time. Clean and rinse the waterers thoroughly.

4. Withhold all water from the birds for two (2) to four (4) hours prior to vaccination to stimulate thirst.

5. Add nonfat dry milk to the water at the rate of one (1) ounce per gallon before mixing the vaccine.

6. Remove the aluminum seal and rubber stopper from a vaccine vial.

7. Fill the vaccine vial two-thirds (2/3) full with clean, cool water and mix gently.

Age of birds

Water per 1,000 doses vaccine

2-4 weeks

2.5 gallons (9.9 L)

4-8 weeks

5 gallons (18.9 L)

8 weeks or older

10 gallons (37.9 L)

9. Distribute the vaccine solution among the waterers. Avoid direct sunlight.

10. Do not provide any other drinking water until all of the vaccine mixture has been consumed.

Spray Aerosol Vaccination: Use only for revaccination of healthy chickens two (2) weeks of age or older. Do not use for initial vaccination.

Use a sprayer delivering an aerosol-like mist to disperse the rehydrated vaccine quickly and evenly throughout a house of chickens.


1. Remove the aluminum seal and rubber stopper from the vaccine vial.

2. Fill the vaccine vial full with cool, distilled water. Pour the dissolved vaccine into a container and add approximately 500 mL of cool, distilled water per 5,000 doses of vaccine. Mix thoroughly.

3. For spray aerosol vaccination of a house of chickens, apply at the rate of 500 mL per 5,000 chickens.

4. Example: 20,000 birds will require 2,000 mL (approximately 2 quarts) of rehydrated vaccine.

5. Place the vaccine solution into the sprayer canister, set the discharge control and walk through the house spraying at the rate of 1,000 birds per minute. Direct the spray above the heads of the birds.

6. Whatever volume of vaccine solution is used, take care to administer 5,000 doses of vaccine to 5,000 birds.

7. Prior to spraying, reduce the air flow to a minimum. Keep air flow reduced for 20 minutes following spray vaccination.

8. Avoid direct contact with the vaccine solution. Wear goggles and a mask while spraying a live virus vaccine.

9. Any equipment used for the application of a live virus vaccine should not be used for any other purpose.
