Abstract

Captive Eld's deer (Rucervus eldi thamin) were evaluated for the presence of rabies virus-neutralizing antibodies using a rapid fluorescent focus inhibition after vaccination with either a live canarypox-vectored recombinant rabies vaccine or a killed monovalent rabies vaccine. Twelve deer were vaccinated with 1.0 ml of killed, adjuvanted, monovalent rabies vaccine at 5-33 mo of age then annually thereafter, and 14 deer were vaccinated with 1.0 ml nonadjuvanted, live canarypox-vectored rabies vaccine at 3-15 mo of age then annually thereafter. Banked serum was available or collected prospectively from deer at 6 mo and 1 yr after initial vaccination, then collected annually. Rabies virus-neutralizing antibodies considered adequate (>0.5 IU/ml) were present in 20/34 samples vaccinated with canarypox-vectored rabies vaccine and in 12/14 samples vaccinated with killed adjuvanted rabies vaccine. Poor seroconversion was noted in deer less than 6 mo of age vaccinated with the canarypox-vectored rabies vaccine.
