Target Species
One day old chickens.
Indications for use
In one day-old chickens: active immunisation against Infectious Bronchitis in order to reduce infection with Massachusetts serotype of Infectious Bronchitis virus.
Onset of immunity: 21 days
Duration of immunity: 6 weeks after a single administration.
Contraindications
None.
Special warnings for each target species
Vaccinate healthy birds only.
Special precautions for use in animals
Vaccine viruses can spread to unvaccinated birds. Infection of unvaccinated chickens with the vaccine virus from vaccinated birds does not cause any signs of disease. Reversion to virulence trials carried out in the laboratory have shown that the vaccine viruses do not acquire any pathogenic characteristics after at least 5 passages in chickens.
Special precautions to be taken by the person administering the veterinary medicinal product to animals
Wash and disinfect hands and equipment after vaccinating. For more information, contact the manufacturer.
Adverse reactions:
Bronchial rales, not associated with respiratory distress or any general sign, are very common between 5 and 14 days after vaccination.
The frequency of adverse reactions is defined using the following convention:
- very common (more than 1 in 10 animals displaying adverse reactions during the course of one treatment).
- common (more than 1 but less than 10 animals in 100 animals).
- uncommon (more than 1 but less than 10 animals in 1,000 animals).
- rare (more than 1 but less than 10 animals in 10,000 animals).
- very rare (less than 1 animal in 10,000 animals, including isolated reports).
Use during pregnancy, lactation or lay
The vaccine is only intended for use in newly hatched chicks and is not appropriate after the age of one day. The data available on the properties of the strain are not indicative of a detrimental effect on the reproductive tract.
Interactions
Safety and efficacy data are available which demonstrate that this vaccine can be mixed and administered with a Boehringer Ingelheim’s frozen live vaccine against Newcastle disease containing VG/GA-Avinew strain, and can be administered on the same day but not mixed with a Boehringer Ingelheim’s recombinant HVT vaccine expressing the protective antigen of the Infectious Bursal disease virus.
No information is available on the safety and efficacy of this vaccine when used with any other veterinary medicinal product except the products mentioned above. 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
Route: Respiratory route (spray application).
Reconstitution of the vaccine:
1. Prepare a container filled with the appropriate quantity of clean non-chlorinated drinking water (7 to 30 ml per box of 100 chicks according to the type of sprayer used in the hatchery).
2. Dissolve a number of tablets corresponding to the number of doses to be administered in a container holding the appropriate quantity of clean non-chlorinated water prepared at step 1.
3. Wait until complete dissolution of the tablets before using the vaccine solution. The reconstituted vaccine is a yellow solution, and a foam layer may form over the surface.
4. Where HatchPak Avinew frozen suspension (ampoules carried by a green cane) is to be used concurrently, transfer the content of one ampoule prepared according to the leaflet’s instructions into the container which has previously been used to prepare Hatchpak IB H120 Neo.
5. The reconstituted vaccine prepared according to the instructions is ready for use. It should be used immediately after preparation and therefore the tablets should only be removed from blisters when needed.
Posology: One administration from day-old, via the respiratory route (spray application).
Method of administration:
- The vaccine is intended for mass vaccination of chicks in the hatchery, the vaccine solution should be applied as a coarse spray whilst the chicks are in their chick boxes.
- Spray the vaccine solution above the birds using a sprayer that enables production of drops of 100 µm or more that cover the chicks with the vaccine, so the vaccine is administered directly to their eye and the droplets pearls that shine on the down will encourage them to pick them off of each other and from the surface of the box.
- For effective vaccine distribution, make sure that birds are closely confined together during spraying. During and after vaccination ventilation should be switched off in order to avoid turbulences.
Overdose
No side effects other than those listed in “Adverse reactions” have been observed following the administration of more than 10 times the recommended dose of vaccine.
Withdrawal periods
Zero days.
