Poulvac ILT — SPC Details

Source: VMD Summary of Product Characteristics (SPC). Last updated 27 Mar 2026.

For the prevention of mortality and clinical signs due to infection with avian infectious
laryngotracheitis virus. Onset of immunity is 14 days post vaccination. Duration of
immunity has not been assessed, however, experience from field use indicates that
once vaccinated birds remain immune to avian infectious laryngotracheitis virus
infection during entire laying period.

Revised: May 2025
AN: 00173/2025

Vaccine is administered to chickens from 4 weeks of age by eye drop.
1000 doses of freeze dried vaccine must be completely dissolved in 30 ml of the
sterile diluent provided and a drop of dispenser calibrated to deliver at least three
hundredth of a millilitre per drop must be used.

AN: 00173/2025
Remove the rubber stopper from the vaccine vial and add sterile diluent to half fill the
vial. Replace the rubber stopper and shake gently so that all the vaccine material is
completely dissolved.
Pour the dissolved vaccine into the remaining sterile diluent and shake again until
completely mixed. The sterile diluent should be at room temperature when used.
Fit the drop dispenser on the bottle. Hold the bird so that one eye is pointed upwards
and allow one drop of vaccine to fall into the eye.
Contact with the disinfectant makes the vaccine ineffective.
Protect the reconstituted vaccine from heat or direct sunlight.

Do not vaccinate diseased birds (except in case of an emergency vaccination).

About four days after vaccination, redness and some swelling of the conjunctiva, or
laboured breathing may be seen. Under good hygienic conditions, this reaction will
not last longer than three days.

In order to prevent spread of vaccine strain from vaccinated flocks to non-vaccinated
flocks, all non-vaccinated birds present on the farm must be vaccinated at the same
time.
