Vaccination Programs

Many factors must be considered in determining the vaccination program for a particular farm or poultry operation. To be fully effective, the vaccine must be administered to healthy receptive birds held in proper environment under good management. In addition, the response may be modified by the age of the birds and their immune status. Seldom does 1 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.

Preparation of Vaccine

Do not open the vaccine until ready to begin vaccination. Use vaccine immediately after opening.

1. Shake well
2. Remove the tear-off seal and stopper from the vaccine vial. Vaccine is now ready for use.

FOR CHICKENS FROM 10 TO 12 WEEKS OF AGE

1. Vaccine is applied to the web of the wing. Use the enclosed two-pronged applicator.
2. A dose of 0.01 mL should be administered to each bird by dipping the applicator in the vaccine mixture, allowing the applicator grooves to fill with liquid, and stabbing the webbed portion of the wing from beneath. Avoid feathered areas of the web.
