Studied was a freeze-dried vaccine against fowl pox, which was produced with the pigeon type of the New Jersey strain and was considered an innocuous and immunogenic biopreparation for birds of all ages. There were neither complications after vaccination via the wing web or through rubbing the leg nor any drop in egg laying. The vaccine stored at 4 degrees C retained its immunogenic properties in the course of one year (the period of observation).
