Target species
Broiler chickens from 1 day of age.
Indications for use, specifying the target species
Reduces clinical signs and lesions of respiratory disease caused by the coronavirus variant, strain CR88 (793B) in broiler chickens.
Immunity has been demonstrated 21 days after vaccination.
Duration of immunity: 6 weeks after vaccination.
Contra-indications
In the absence of trial data, future layers or breeders and chickens in lay must not be vaccinated.
Special warnings for each target species
GALLIVAC IB88 NEO vaccination does not replace the vaccination schedule against classical Infectious Bronchitis.
Special precautions for use in animals
Only healthy birds should be vaccinated.
The vaccinal virus can spread to non-vaccinated birds, but no trend towards reversion to virulence was demonstrated in laboratory trials.
Nevertheless, care should be taken to prevent spread of vaccine virus to susceptible birds such as replacement layers and young birds.
It is recommended to vaccinate all chickens on a site at the same time.
Special precautions to be taken by the person administering the veterinary medicinal product to the animals
Care should be taken during dissolution and administration of the vaccine. During preparation of the vaccine suspension and administration by coarse spray, the operator should wear respiratory and eye protection conforming to current European standards. For further information contact the manufacturer.
Hands should be washed and disinfected after vaccinating.
Adverse reactions (frequency and seriousness)
Mild respiratory signs have been reported very commonly in studies and signs may persist for up to 23 days.
Frothy lacrimation has been reported commonly in studies.
The frequency of adverse reactions is defined using the following convention:
- very common (more than 1 in 10 animals treated displaying adverse reaction(s))
- common (more than 1 but less than 10 animals in 100 animals treated)
- uncommon (more than 1 but less than 10 animals in 1,000 animals treated)
- rare (more than 1 but less than 10 animals in 10,000 animals treated)
- very rare (less than 1 animal in 10,000 animals treated, including isolated reports)..
Use during pregnancy, lactation or lay
Do not use in future layers, or breeders and chickens in lay.
Interaction with other medicinal products and other forms of interaction
No information is available on the safety and efficacy of this vaccine when used with any other veterinary medicinal product. A decision to use this vaccine before or after any other veterinary medicinal product therefore needs to be made on a case by case basis.
Amounts to be administered and administration route
-One dose of vaccine to be administered by nebulisation from 1 day old.
-Use clean equipment, free from any antiseptic and/or disinfectant for the preparation and administration of the vaccine.
-Use demineralised or distilled water for the preparation and administration of the vaccine. Dissolve the tablets in a volume of demineralised or distilled water appropriate for the type of spraying equipment to be used, and the number of doses to be administered.
-Wait until complete dissolution of the tablets before using the vaccine solution.
-Spray equipment should be used which is capable of producing droplets of average diameter 80 to 150 µm. Do not use "fogger"-type sprayer or equipment producing droplets of less than 50 microns for the administration of the vaccine.
-The vaccine should be sprayed as evenly as possible over the birds to ensure that each bird receives a full dose (for further information on sprayer equipment, contact the manufacturer).
-The ventilation system of the poultry house should be inoperative during the spray administration.
Overdose (symptoms, emergency procedures, antidotes), if necessary
Administration of ten doses of vaccine may induce mild upper respiratory signs that may persist for up to 17 days and/or a transient reduced weight gain.
Withdrawal Period(s)
Zero days.
