Bursal Disease Vaccine
STORE IN REFRIGERATOR UNDER 7°C (45°F)
Drinking Water Administration
Use only in chickens to be placed on premises with a history of Infectious Bursal Disease.
READ FULL DIRECTIONS BELOW CAREFULLY
This vaccine contains an attenuated strain of Infectious Bursal Disease (IBD) virus.
When administered properly to healthy, susceptible chickens, BURSA-VAC vaccine is recommended for the vaccination of chickens 7 to 14 days of age as an aid in the prevention of Bursal Disease. Use only on premises with a history of IBD infection. However, if chickens are from immune parents, vaccination should be delayed until they are at least 10 days of age, for best protection.
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 immunocompetent 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.
Only vaccinate healthy chickens
A few vaccinated chickens will usually develop symptoms, i.e. depression, anorexia and diarrhea and occasionally chickens may die with typical lesions. In most instances, the total mortality in the vaccinated flocks is under 1%.
Field observations indicate that natural outbreaks of IBD in unvaccinated flocks will approximate at least 3% mortality, with numerous culls produced.
Consult your poultry pathologist for further recommendations based on conditions existing in your area at any given time. 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 stress conditions at the time the vaccine is administered.
Care should be taken to avoid the spread of virus from vaccinated flocks to clean premises.
REHYDRATION OF THE VACCINE
1. Tear off the aluminum seal from the vial containing the dried vaccine.
2. Lift off the rubber stopper.
3. Carefully pour clean, non-chlorinated water into the vaccine vial until the vial is approximately 2/3 full.
4. Put back the rubber stopper and shake vigorously until all material is dissolved.
5. The vaccine is now ready for drinking water use in accordance with the directions below.
Drinking Water Administration
For vaccination of healthy chickens from 7 to 14 days of age
1. Remove all medication, sanitizers, and disinfectants from the drinking water, preferably 72 hours before vaccination, and 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 rehydrated vaccine at the rate of 5.7 liters (1.3 Imp. gal.) per 1,000 doses to clean, non-chlorinated water.
7. Distribute the vaccine solution, as prepared above among the waterers provided for the chickens. Avoid placing waterers in direct sunlight.
8. Provide no other drinking water until all the vaccine treated water has been consumed.

Therefore, directions for use should be followed carefully.
