FIELD VACCINATION 3.4 Wing Web Vaccination This method is commonly used for Fowl Pox, Avian Encephalomyelitis, Chicken Anemia and Live Fowl Cholera. Vaccine Preparation » The preparation of this vaccine is similar to that of the eye drop vaccine. The vaccine is lyophilized and must be reconstituted in the same manner as other vaccines. » Only use the specific diluent which comes packaged with the vaccine. Shake the vaccine vial carefully, turning the vial from one side to the other without tapping.
Vaccine Administration COBB VACCINATION MANAGEMENT GUIDE » Administer the vaccine in the center of the wing web, using a two-pronged needle applicator or other wing web applicator (Grant inoculator or others). Dip the two-pronged applicator into the diluted vaccine and pierce the web on the underside of the wing, avoiding feathers, blood vessels and bones. Do not touch the bottom of the vaccine container when dipping wing web applicators. This can dull the needles and waste vaccine. » Change needles every 500 to 1,000 birds. Monitor for signs of dulling or burr formation. Post Vaccination » 7 to 10 days after vaccination, check for “vaccinal takes”. Check at least 50 birds per house.
Please refer to Vaccination Quality Control section for examples (Section 4). Before vaccination: the vaccinator should gently lift the wing to clearly expose the wing web area and to visualize the placement of the needle applicator. During vaccination: the handler should securely hold the bird to optimize human safety and bird welfare. After vaccination: the vaccinator should see a small area of blue dye in the wing web and no blood. The vaccination crew supervisor should regularly check birds throughout the process to verify the location of the dye and correct placement of the vaccine in the wing web. ANIMAL WELFARE TIPS 23
