Responses to the Plowright Rinderpest vaccine by 43 calves and 70 adult cattle in Uganda in 1990, through the production of IgG antibodies, were monitored for 4 weeks using the ELISA assay. 80% of the calves were seronegative before vaccination of which 32% remained seronegative and 68% subsequently seroconverted at 2 weeks postvaccination. 20% of the calves were seropositive before vaccination but registered a decline during the 2nd and 4th weeks postvaccination. 50% of adult Ankole cattle seroconverted after 3 weeks postvaccination, while the other 50% of them, which were seropositive before vaccination, showed a decline in seronegative levels during the first 2 weeks postvaccination, but increased again at the 4th week. 90% of Friesian adult cattle were seronegative before vaccination; however, they all seroconverted within the 2nd week of postvaccination. The other 10% remained seropositive, with a slight decline of antibody levels during the 4 weeks after vaccination.
