Simultaneous vaccination of cattle against foot-and-mouth disease and rinderpest

A total of 118 local cattle in the Sultanate of Oman were divided into three groups, one which received a trivalent inactivated foot-and-mouth disease vaccine, another which received attenuated tissue culture rinderpest vaccine and a third which received both vaccines simultaneously at separate sites on opposite sides of the neck. The serological response to vaccination was monitored at day 0, 21 and 42 in virus neutralisation tests. The simultaneous administration of the two vaccines produced no ill effects and the serological responses did not differ significantly from the response to either vaccine given separately.
