Canine distemper virus (CDV) neutralizing antibody (NT) titer was examined against the sera from 7 giant pandas aged between 8 to 21 years housed at Chengdu Research Base of Giant Panda Breeding,China.Anti-CDV NT titer against the Onderstepoort strain showed a wide range from × 2 to×256 (median=16),even though the ani-mals had been receiving an attenuated live vaccine made from an anonymous domestic CDV strain twice a year since 2003.A single administration of attenuated morbillivirus antigen often be enough to give corresponding host a steady immunogenicity.Anti-CDV-NT variation in the giant panda suggests some deficiency in the relationship between the vaccine and the host.
