This study was undertaken in 2013 and 2014 to investigate the seroprevalence of
antibodies against foot-and-mouth disease vaccine (FMDV) in yaks, being core
member of Bovidae living in the high-altitude mountains of China and adjacent
countries. Results showed that serotype O FMDV elicited relatively higher antibody
levels than Asia-1 in yaks. Either O or Asia-1 vaccine induced greater immunity in
yaks in 2014 than that in 2013
