The results of this experiment indicate that ewes should be vaccinated
3 to 4 wk prior to parturition and that there is no benefit of
vaccinating lambs prior to 6 wk of age. Further studies are needed
to recommend an adequate immunization schedule for lambs after
weaning or whether fast growing lambs from vaccinated ewes need
to be immunized.
