Description
Oral solution, eye drops solution or spray solution after reconstitution of the freeze-dried vaccine in water for chickens
| Active substance: | Per dose |
|---|---|
| Infectious bronchitis virus strain H120 | 103.0 - 104.9 EID50 |
*EID50: Embryo infective dose 50%
INDICATIONS
For the vaccination of chickens to prevent respiratory disease caused by Massachusetts strains
of avian infectious bronchitis virus and to act as a live primer for inactivated Massachusetts
strain vaccines.
The onset of immunity is from 25 days post vaccination.
Protection of chicks will be of approximately 16 weeks duration at which age the chickens
may be vaccinated with an appropriate inactivated IBV vaccine.
CONTRAINDICATIONS
Do not use in unhealthy birds
ADVERSE REACTIONS
A mild vaccination reaction can be observed in the form of transient, slight respiratory symptoms.
TARGET SPECIES
Chickens from one day of age.
DOSAGE, ROUTE AND METHOD OF ADMINISTRATION
One dose per chicken to be administered by eye drop, with drinking water or by spray. The
quantity of water to be used depends on the method of administration. Never use less than 1
dose per bird.
Eye drop
For chickens at one day of age.
Reconstitute vaccine by dissolving in deionised water for eye drop at the rate of 30 ml per
1,000 doses.
The deionised water should be at room temperature when used.
Administer by dropper at the rate of one drop per chick on to one eye.
Hold the chicken so that one eye is pointing upwards and allow one drop of vaccine to fall
into the eye.
Chickens should swallow during vaccination.
Drinking water
Discontinue any drinking water medication 24 hours before vaccination. Water containing a
high level of free chlorine should not be used. A general indication is that if chlorine can be
detected in the water by smell or taste it could deactivate the living virus.
If so, half a litre (1 pint) of skimmed milk should be thoroughly mixed into every 20 litres (5
gallons) of water or skimmed milk powder added at a rate of two grams per litre of water
before adding vaccine.
Only perfectly clean and rust free utensils and drinkers (preferably plastic) should be used,
and disinfectants must not be used for cleaning. Ensure that there is enough drinking trough
space to allow all birds immediate access to the vaccine. No untreated water should be
available until the treated water has been consumed.
Withhold drinking water for 2 hours before vaccination to stimulate thirst. Remove the
aluminium seal from the vaccine vial. To dissolve the vaccine pellet, the rubber stopper
should then be removed whilst the vial is immersed in a plastic measuring jug containing 1
litre (approximately 1 quart) of clean cool water. Half fill the vial with water, replace the
stopper and shake to dissolve any remaining vaccine.
The vaccine concentrate should then be added to and thoroughly mixed with sufficient
drinking water to last for approximately 2 hours.
The approximate drinking water requirements for vaccination can be calculated from the age
of the birds. Use as many litres of water as the age of the birds in days, per 1000 birds, up to a
maximum of 40 litres per 1,000 birds.
Distribute the diluted vaccine evenly in the drinkers. Do not expose prepared drinking water
vaccine to sunlight.
Return to regular watering only after the vaccine water has been consumed. The vaccine
solution is best divided so that the drinkers are charged at least twice with vaccine to ensure a
more widespread uptake.
If nipple drinkers are employed, ensure that header tanks are continually refilled with water
containing vaccine.
The vaccine may be used in automatic watering equipment. However, the main supply should
only be turned on when all the vaccine treated water has been consumed.
NB: Check that birds are never left without water after vaccine treatment.
Spray
The vaccine should be dissolved as described under drinking water administration. The
vaccine concentrate should then be added to the water in the sprayer tank and thoroughly
mixed.
The equipment should provide a droplet size of 0.12 to 0.15 mm diameter. The distance from
the spraying head to the bird must be approximately 50 cm. Use 0.15 to 0.5 litres of water per
1,000 birds depending upon the type of spray equipment to be used.
Spray the sides of the box first from a height of 30-50 cm (12-18 inches). Ensure no water
spillage by rotating the sprayer end to spray into the box at each turn. The operator may need
to stand on a box to correctly spray two boxes at the right angle. Hold chickens in boxes for
approximately 30-45 minutes following vaccination.
Ensure the temperature in the holding area is 21-27oC (70-80oF) and draught free, to avoid
chilling. Chickens should be neither overheated nor chilled following coarse spray
vaccination.
WITHDRAWAL PERIOD
Zero days
SHELF LIFE
Shelf-life of the veterinary medicinal product as packaged for sale: 24 -36 months (National
label conditions must be observed by country.)
Reconstituted vaccine should be used within 4 hours.
SPECIAL STORAGE PRECAUTIONS
Store and transport refrigerated (2oC - 8oC).
Protect from light.
Do not freeze.
SPECIAL WARNINGS
Maternally derived antibody (MDA) can interfere with the development of active immunity.
Where it is likely that recent field infection or vaccination of the parent flock has stimulated a
high antibody titre and consequently a high level of MDA, the timing of the vaccination
programme should be planned accordingly.
In any animal population there will be a small number of individuals which fail to respond
fully to vaccination. Successful vaccination depends upon correct storage and administration
of the vaccine and the animal’s ability to respond. Immune competence can be influenced by
genetic factors, intercurrent infection, age, nutritional status, concurrent drug therapy, stress,
etc.
Special precautions for use in animals
Care should be taken in the planning and implementation of vaccination programmes as
vaccine virus may spread from vaccinates to non-vaccinated chickens. It is recommended that
all chickens on a site be vaccinated with this product.
Can be used before the onset of lay in chickens intended for breeding.
Do not administer to birds in lay or within 4 weeks of point of lay.
No information is available on the safety and efficacy from the concurrent use of this vaccine
with any other. It is therefore recommended that no other vaccines should be administered
within 14 days before or after vaccination with the product.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals
If the vaccine is administered by spray, the eyes must be protected by safety goggles and the
nose and mouth by a dust mask. A helmet with filtered air circulation may be used instead of
goggles and a mask
On completion of vaccination, all empty or part-used vials, any residual vaccine and the
materials used for vaccination should be burnt or disinfected in a disinfectant approved for
use under the Diseases of Animals (Approved Disinfectants) Orders.
