Poulvac Bursaplex (Canada)

Directions For Use

Bursal Disease Vaccine

Live Virus

Product Indications

Bursaplex is for vaccination of healthy chickens as an aid in preventing infectious bursal disease. It is recommended for subcutaneous injection of chickens at one day of age or in ovo vaccination of 18- to 19-day-old, embryonated chicken eggs using the Embrex^® Inovoject^® System. It is essential that the birds be maintained under good environmental conditions and that exposure to disease viruses be reduced as much as possible. Bursaplex is a virus-antibody complex vaccine that contains a live strain of bursal disease virus derived from chicken embryo in conjunction with bursal disease antiserum.

Rehydration of Vaccine

1. Dilute the vaccine only as directed while observing aseptic technique and precautions for safe handling.

2. For each 1,000 doses of vaccine to be administered by subcutaneous injection, use 200 mL of sterile diluent.

3. For each 4,000 doses of vaccine to be administered in ovo, at 0.05 mL/egg (50 µL/egg), use 200 mL of sterile diluent.

4. Using a 20-mL sterile syringe and an 18-gauge x 1.5” needle, rehydrate only the vials of vaccine that are to be used immediately.

5. Aseptically transfer enough diluent to the vial containing the lyophilized virus to fill it about 3/4 full. Shake the contents gently until the vaccine is evenly suspended.

6. Aseptically remove the virus suspension from the vial and combine into the remaining diluent. Thoroughly mix the vaccine and diluent by massaging and inverting. Use immediately.

In ovo Administration

Before initiating in ovo vaccination, carefully read and follow the Embrex Inovoject System operator’s manual. Failure to follow instructions may result in personal injury and embryonic morbidity/mortality. Only healthy embryonated eggs should be vaccinated.

1. Sanitize the Embrex Inovoject System before and after use.

2. Inject a 0.05-mL dose into each embryonated egg.

3. Use the entire contents of the vaccine container within one hour after mixing.

Subcutaneous Injection Method

Important: Sterilize vaccinating equipment by autoclaving 15 minutes at 121°C or by boiling in water for 20 minutes. Never allow any chemical disinfectant to come in contact with vaccinating equipment.

1. Use a sterile automatic syringe with a 20-22 gauge, 3/8-1/2” needle, set to accurately deliver 0.2 mL. Check accuracy of delivery several times throughout vaccination.

2. Hold the chicken by the back of the neck, just below the head. The skin in this area is raised by gently pinching with the thumb and forefinger. Insert the needle beneath the skin directing it away from the head. Inject 0.2 mL per chick and avoid hitting muscles and bones in the neck.

3. Use entire contents of the vaccine within one hour of mixing.
