ABSTRACT
The present work was designed to investigate the immune response of goats to the concomitant immunization with PPR and bivalent FMD (type A and O) vaccines. The study included four groups of local breed goats, where the first received modified live PPR virus vaccine; the second received inactivated bivalent FMD virus vaccine; and the third group received simultaneous vaccination with PPR and FMD vaccines. A separate group was left non-vaccinated and served as control. All animals remained clinically normal throughout the whole experiment period. A satisfactory humoral immune response to both virus vaccines in vaccinated animals was identified by SNT and ELISA. It was found that there is no difference in the immune response among different vaccinated groups and there is no drawbacks noticed from combination of the two vaccines in the field.
