Abstract
The results of six vaccination trials carried out with a formalin inactivated oil adjuvant Egg Drop Syndrome 76 (EDS 76) vaccine prepared from strain BC14 are presented. The trials carried out in breeding and laying flocks of fowls always included vaccinated and unvaccinated birds. The birds were vaccinated once during the rearing period by intramuscular injection. Field infection with EDS 76 virus was confirmed by the sero‐logical conversion to EDS antibody positive in the unvaccinated birds. In the unvaccinated birds field challenge was followed by typical EDS 76 symptoms, whereas the vaccinated birds were protected and layed normally throughout the trials.Keywords
