3. Carefully pour clean, cool, non-chlorinated water into the vaccine vial until the vial is approximately two-thirds full.

4. Replace the rubber stopper and shake vigorously until all the material is dissolved.

5. The vaccine is now ready for drinking water use in accordance with directions below. For best results be sure to follow directions carefully.

Drinking Water Administration: For chickens four weeks of age or older.

1. Remove all medications, sanitizers, and disinfectants from the drinking water, preferably 72 hours before vaccinating, and for 24 hours following vaccination.

2. Provide enough watering space so that at least two-thirds of the chickens can drink at one time.

3. Scrub waterers thoroughly and rinse with fresh, clean water.

4. Withhold water for 2 hours before vaccinating to stimulate thirst.

5. Rehydrate the vaccine as directed above.

6. Add the rehydrated vaccine to clean, cool, non-chlorinated water and mix in accordance with the following chart:

Age of Chickens	For each 1,000 doses add to this amount of water
4-8 weeks	5 gal. (19 L)
Over 8 weeks	10 gal. (38 L)

7. Distribute the solution, as prepared above, among the waterers provided for the chickens. Avoid placing the waterers in direct sunlight.

8. Provide no other drinking water until all of the vaccine treated water has been consumed.

Precaution(s)

Store vaccine in refrigerator under 45°F (7°C). Use entire contents of each vial when first opened. Burn containers and all unused contents.

Polybron B1 Caution(s)

Only vaccinate healthy chickens.

Consult your poultry pathologist for further recommendations based on conditions existing in your area at any given time.

The vaccination program for replacement pullets should not be started after chickens are 16 weeks of age.

Chickens should not be placed on contaminated premises. Exposure should be avoided immediately after vaccination because it takes up to 10 days to develop resistance.

All susceptible chickens on the same premises should be vaccinated at the same time. If this is not possible, then strict isolation and separate caretakers should be employed for non-vaccinated units. Efforts should be taken to reduce stressful conditions at the time the vaccine is administered.

Notice: All Schering-Plough Animal Health vaccines released for sale meet the requirements of the licensing authority (U.S. Department of Agriculture) in regard to safety, purity, potency and the capacity to immunize normal, susceptible chickens.

The capacity of this vaccine to produce satisfactory results depends upon many factors including, but not limited to, conditions of storage and handling by the user, administration of the vaccine, health and responsiveness of individual animals and the degree of field exposure. Therefore, directions for use should be followed carefully.

The use of this vaccine is subject to applicable state and federal laws and regulations.

Warning(s)

Do not vaccinate within 21 days before slaughter.

Newcastle Disease virus can cause inflammation of the eyelids of humans, lasting two or three days. The user should avoid contaminating hands, eyes and clothing with this vaccine.

Discussion

Vaccination Programs: Many factors must be considered in determining the proper vaccination program for a particular farm or poultry operation. To be fully effective, the vaccine must be administered to healthy receptive chickens held in a proper environment under good management. In addition, the response may be modified by the age of the chickens and their immune status. Seldom does one vaccination under field conditions produce complete protection for all individuals in a given flock. The amount of protection required will vary with the type of operation and the degree of exposure that a flock is likely to encounter. For these reasons, a program of periodic revaccination may be required.
