Avian Encephalomyelitis Vaccine Indications For Use

The Avian Encephalomyelitis vaccine made by using the chicken embryo propagated strains of Avian Encephalomyelitis has been developed for use in chickens aged 8 weeks or older.


This product is not recommended for use in unhealthy or diseased chickens, and chickens which are not maintained under good environmental or sanitary conditions.


The vaccinated chickens should not be placed on contaminated premises. Exposure should be avoided immediately following vaccination. Immunity has been shown in studies to develop at 21 days post vaccination. All susceptible chickens on the same premises should be vaccinated at the same time. If this is not possible, then strict isolation and separate caretakers should be employed for non-vaccinated chickens. Efforts should be made to reduce stress conditions at the time of vaccine administration. Do not mix with other products, except as specified on the label. In case of human exposure, contact a physician. Use entire contents when opened.
