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.

In ovo Administration:

  1. Inoculate each 18-day-old chicken embryo with a full dose (0.05 ml or 0.1ml).
  2. Entire contents of container must be used within 1 hour after mixing or be discarded according to caution statement No. 11.
  3. After reconstitution, the vaccine should be kept cool and gently agitated frequently.

Subcutaneous Administration:

  1. Hold the chicken by the back of the neck just below the head. The loose skin in the area is raised by gently pinching with the thumb and forefinger. Insert the needle beneath the skin in a downward direction away from the head. Inject 0.2 ml per chicken.
  2. Avoid hitting the muscles and bones in the neck.
  3. Entire contents of container must be used within 1 hour after mixing or be discarded according to caution statement No. 11.
