PREVEXXION RN Concentrate and Solvent for Suspension for Injection

Vaccinate healthy animals only.

Special precautions for safe use in the target species:
The vaccine virus spreads; care should be taken to prevent such spread in multi-age
sites.
A good immune response is reliant on the reaction of an immunogenic agent and a fully
competent immune system. Immunogenicity of the vaccine antigen will be reduced by
poor storage or inappropriate administration.
Immunocompetence of the animal may be compromised by a variety of factors including
poor health, nutritional status, genetic factors, concurrent drug therapy and stress.
Under certain conditions, for example extreme disease pressure and variant challenge,
fully immune birds may succumb to disease. Therefore, successful vaccination may not
be synonymous with full protection in the face of a disease challenge.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals:
The operator should be aware of the general precautions to be taken when handling
liquid nitrogen and/or material at very low temperature. Ampoules may explode on
sudden temperature changes; therefore, the operator should protect himself with gloves
and a visor. When removing an ampoule from a cane hold the palm of a gloved hand
away from body and face.
First aid treatment of frost bite injuries:
°C  1 ºC or use body heat. There will be considerable pain during warming, but this is
normal. Do not rub affected area, seek medical advice.
After handling vaccine operators should wash and disinfect hands with an approved
disinfectant.
CAUTION: The ampoules have been known to explode on exposure to sudden
temperature changes. Do not thaw in hot water or ice-cold water. Thaw the ampoules in
clean water at 25 °C – 27 °C.
