Reporting adverse events is important. It allows continuous safety monitoring of a
veterinary medicinal product. Reports should be sent, preferably via a veterinarian, to
either the marketing authorisation holder or the national competent authority via the
national reporting system. See section “Contact details” of the package leaflet.

Vaccinate healthy animals only.

Special precautions for use in animals
As this is a live vaccine, the vaccine strain is excreted from vaccinated birds and may
spread to turkeys. Safety trials have shown that the strain is safe for turkeys.
However, precautionary measures have to be followed in order to avoid direct or
indirect contact between vaccinated chickens and turkeys.
During subcutaneous vaccination, care should be taken to prevent damage of the
blood vessels in the neck of the chickens.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals
The handling of liquid nitrogen should take place in a well-ventilated area.
Innovax-ILT is a virus suspension packed in glass ampoules and stored in liquid
nitrogen. Before withdrawing ampoules from the liquid nitrogen canister, protective
equipment consisting of gloves, long sleeves and a facemask and goggles should be
worn. In case of an accident to prevent serious wounds by either the liquid nitrogen
or the ampoules when removing an ampoule from the canister, hold palm of gloved
hand away from body and face. Care should be exercised to prevent contaminating
your hands, eyes and clothing with the ampoule content. CAUTION: Ampoules have
been known to explode on sudden temperature changes. Do not thaw in hot or ice-
cold water. For this reason, thaw the ampoules in clean water at 25 °C – 27 °C. In
case of accidental self-injection, seek medical advice immediately and show the
package leaflet or the label to the physician.
