HAEMOPHILUS PARAGALLINARUM BACTERIN
This vaccine is prepared from three inactivated strains of Haemophilus paragallinarum belonging to serotypes A, B, and C (Page classification scheme), and suspended in the aqueous phase of an oil adjuvant emulsion.
For the vaccination of healthy chickens 5 weeks of age or older as an aid in the prevention of Haemophilus paragallinarum infection (CORYZA).
ADMINISTRATION: Allow the vaccine to reach ambient temperature, 16° to 27°C (60° to 80°F), shake well before use and periodically during use. Inject 0.5 ml subcutaneously in chickens in the back of the neck midway between the head and body in a direction away from the head using an 18-gauge needle. Do not inject into muscle tissue or neck vertebrae. Vaccinate healthy chickens at least 5 weeks of age. A second vaccination is recommended a minimum of 4 weeks following initial vaccination and 3-4 weeks prior to the onset of lay.
IMMUNITY: Chickens administered two doses with the second dose given a few weeks prior to the onset of lay will achieve a protective level of immunity during the laying period with only small variations between individual chickens.
VACCINATION REACTION: Clinical reactions may occur as a result of transient swelling in the neck region following vaccination. These reactions may be aggravated by improper vaccination technique. If shock is observed, this must usually be ascribed to stress by handling.
Store at 2° to 7°C (35° to 45°F) in the dark. Do not freeze.
1. TO AVOID HUMAN INJECTION, EXTREME CAUTION SHOULD BE USED WHEN INJECTING ANY OIL EMULSION VACCINE. ACCIDENTAL HUMAN INJECTION MAY CAUSE SERIOUS LOCAL REACTIONS. CONTACT A PHYSICIAN IMMEDIATELY IF ACCIDENTAL HUMAN INJECTION OCCURS.
2. Do not administer this vaccine during the critical egg laying period from onset until after peak production. Administration of this product during the lay period may result in a drop in egg production.
3. Injection of inactivated vaccine into breast muscle may create processing plant problems under certain conditions.
4. Do not vaccinate chickens within 42 days before slaughter.
5. This vaccine contains thimerosal a preservative.
