Fowl Pox Vaccine

Fowlpox is a slow-spreading viral infection of chickens and turkeys characterized by proliferative lesions in the skin that progress to thick scabs (cutaneous form) and by lesions in the upper GI and respiratory tracts (diphtheritic form). Virulent strains may cause lesions in the internal organs (systemic form). Fowlpox is seen worldwide.

Description

Fowl Pox Vaccine is a chicken embryo propagated, freeze-dried, live virus vaccine for wing web administration in chickens. Vaccination effectively prevents the disease and may limit spread within actively infected flocks. Where fowlpox is prevalent, chickens and turkeys should be vaccinated with a live-embryo or cell-culture-propagated virus vaccine. The most widely used vaccines are attenuated fowlpox virus and pigeonpox virus isolates of high immunogenicity and low pathogenicity. In high-risk areas, vaccination with an attenuated vaccine of cell-culture origin in the first few weeks of life and revaccination at 12–16 weeks is often sufficient.

Health of birds, extent of exposure, and type of operation determine the timing of vaccinations. Because the infection spreads slowly, vaccination is often useful to limit spread in affected flocks if administered when <20% of the birds have lesions. Passive immunity may interfere with multiplication of vaccine virus; progeny from recently vaccinated or recently infected flocks should be vaccinated only after passive immunity has declined.

Vaccinated birds should be examined 1 week later for swelling and scab formation (“take”) at the site of vaccination. Absence of “take” indicates lack of potency of vaccine, passive or acquired immunity, or improper vaccination. Revaccination with another serial lot of vaccine may be indicated.

Fowl Pox Vaccine Indications For Use

The vaccine is recommended for vaccination of healthy chickens aged 8 weeks or older but at least 4 weeks prior to start of lay. When used as indicated, it will aid in preventing the clinical signs caused by the virulent field strains of fowl pox virus.

Administration

Tear off the aluminum seal from the vial containing the freeze dried virus. Lift off the rubber stopper. Remove the seal and stopper from the diluent bottle. Each diluent bottle contains 10 ml of diluent. Pour half of the diluent into the vial containing the freeze dried virus. Replace the rubber stopper and shake the vaccine vial. Pour the partly dissolved vaccine into the diluent bottle to mix with rest of the diluent. Replace the rubber stopper and shake vigorously until the vaccine is dissolved completely. The vaccine is now ready for administration by the wing-web method. For administering the vaccine, hold the bird and spread the underside of one wing outward. Insert the double needle applicator into the vaccine bottle, wetting or charging both needles. Pierce the web of the exposed wing with the double needle applicator charged with vaccine. Insert the double needle applicator into the vaccine vial again and proceed to vaccinate the next bird. During vaccination avoid hitting large blood vessels, bones and the wing muscles with the double needle applicator. Do not inject in any other site except the exposed wing web.

Fowl Pox Vaccine Caution

Do not spill or splatter the vaccine. Burn containers, unused vaccine and accessories prior to disposal. Do not over dilute the vaccine or otherwise extend the dosage. Store unopened vaccine vials at not over 45° F or 7° C. Do not vaccinate within 21 days of slaughter or 4 weeks prior to start of lay. The vaccinated chickens should not be placed on contaminated premises. All susceptible chickens on the same premises should be vaccinated at the same time. If this is not possible, then strict isolation and separate caretakers should be employed for non-vaccinated chickens. Efforts should be made to reduce stress conditions at the time of vaccine administration.
