Abstract:
Criteria for the selection of vaccines against Newcastle disease are presented. Questions related to safety and potency are considered. Intramuscular vaccination of 23 young storks with an inactivated vaccine is described. All storks tolerated the vaccination without recognizable undesired side-effects. The young storks reacted with the production of serum antibodies three weeks post vaccination. No data is yet available on the duration of the persistence of humoral antibodies. The vaccinated mature storks were free of detectable antibodies at the day of vaccination and five months later.
