Vaccination of cattle with live and inactivated rabies vaccines: a study of antibody response

The authors vaccinated 152 cattle divided into three groups against rabies. The first group received the ERA strain and the second group an inactivated vaccine. The third group received the inactivated vaccine on two occasions with an interval of 60 days between the two doses. Their antibody response was surveyed with the fluorescent foci-inhibition test carried out on blood samples collected during a 10-month period. All animals developed an almost identical antibody response. However, at the sixth and tenth months, there was a higher number of seropositive animals in the groups vaccinated with the killed vaccine.
