Active substance
ATC code
Species
Chickens.
Indications
For the active immunisation of chicks from 1 day of age to reduce intestinal lesions and oocysts output associated with coccidiosis caused by Eimeria acervulina, Eimeria maxima, Eimeria mitis, Eimeria praecox and Eimeria tenella and to reduce clinical signs (diarrhoea) associated with Eimeria acervulina, Eimeria maxima and Eimeria tenella.
Onset of immunity: 14 days post-vaccination.
Duration of immunity: 63 days post-vaccination in an environment that permits oocysts recycling.
Dose to be administered and administration route
Oral use.
The method of administration is by coarse spray.
Vaccination schedule:
One dose of vaccine (0.007 ml) from 1 day of age.
Administration:
The method of administration is by coarse spray by using a suitable device (volume delivered: 28 ml/100 chicks, droplet size: 200 – 250 µm and working pressure: 1.5 to 3 bars).
Before starting to prepare the spray solution, ensure there is a clean container with sufficient capacity for preparing the diluted vaccine suspension available. Dilute the vaccine with the relevant volumes of the solvent (HIPRAMUNE T or HIPRACELL) and water, as shown in the following table:

Shake the solvent (HIPRAMUNE T or HIPRACELL) vial. Dilute the content of the vial with clean, room temperature water into an appropriate container.
Shake the vaccine (EVANT) vial and dilute the contents of it into the solvent and water solution. A purplish suspension is obtained after dilution.
Fill the reservoir of the spraying device with all the vaccine suspension prepared. Maintain the diluted vaccine suspension in continuous homogenisation by using a magnetic stirrer while the vaccine is being administered via coarse spray to the chicks.
To improve the uniformity of thevaccination, maintain the chicks inside the transportation box for at least 1 hour in order to let them ingest all the vaccine droplets.
After this time, place the chicks carefully into the litter and continue with regular management practices.
The device should be cleaned after each use. See the manufacturer’s instructions to ensure proper disinfection and maintenance of the device.
Adverse reactions
None.
