201 blood samples were collected by cluster sampling from 7-11 years old children and measles antibody titer was measured by hemagglutination inhibition test. despite testing all the sera, the results were analysed on the 139 samples that had documented vaccination records and no history of measles. among 139 children 44 had received 2 doses of vaccine one dose before 12 and one after 15 months...

After infection of the upper respiratory tract with foot-and-mouth disease (FMD) virus in immunized cattle, a drop in specific serum-neutralizing antibody activity was observed. Vaccinated cattle with high preexposure serum antibody titers had a precipitous drop for the first 4 days after virus exposure, followed by a rise in titer. This drop was also seen in passively immunized cattle with hig...

An inactivated trivalent fowl cholera vaccine consisted of serotypes 1, 3 and 4 Pasteurella multocida strains was prepared. The vaccine provided 70-100% protection against challenge with homologous starins. ELISA assay showed a considerable increase in antibody titer after towice vaccination of 8 weeks chickens. It was found that the trivalent vaccine can induce immunogenic response in vaccinat...
