It is essential that the birds be maintained under good environmental conditions and that exposure to disease viruses be reduced as much as possible.
PREPARATION OF VACCINE
1. Dilute the vaccine only as directed, observing all precautions and warnings for handling.
2. Open only the vials that are going to be used immediately. Move quickly but carefully.
3. Use 200 ml of sterile diluent for each 1,000 doses of vaccine to be injected subcutaneously or for each 4,000 doses of vaccine to be administered in ovo. Remove the cover from the diluent container. Using a sterile syringe, remove 2 ml of diluent and add to the dried vaccine.
4. Allow the vaccine to dissolve, and transfer the dissolved vaccine into the bottle of diluent.
5. Rinse the vaccine vial to be sure of removing all the vaccine.
6. Replace the stopper and thoroughly mix the vaccine and diluent by swirling and inverting.
7. Use the vaccine-diluent mixture immediately as described below.
Use Of Vaccine For in Ovo Administration
Before initiating in ovo vaccination, carefully read and follow the egg injection system operator’s manual. Failure to follow instructions may result in personal injury, embryonic morbidity and mortality.
1. Sanitize the egg injection 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 the vaccine with the diluent.
Use Of Vaccine For Subcutaneous Injection
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 inch needle that is set to accurately deliver 0.2 ml. Check the accuracy of delivery several times during the vaccination procedure.
2. Inject chickens under the loose skin at the back of the neck (subcutaneously), holding the chicken by the back of the neck just below the head. The loose skin in this area is raised by gently pinching with the thumb and forefinger. Insert the needle beneath the skin in a direction away from the head. Inject 0.2 ml per chicken. Avoid hitting the muscles and bones in the neck.
3. Use entire contents of bottle within one hour after mixing the vaccine with the diluent.
Do not vaccinate diseased embryonated eggs or diseased birds.
Vaccinate all birds on the premises at one time.
Administer a full dose to each embryonated egg or to each bird.
Avoid stress conditions during and following vaccination.
Do not place chickens in contaminated facilities.
Exposure to disease must be minimized as much as possible.
