Figure 1.

Median of total daily clinical scores in calves before and after BRSV challenge approximately 11 weeks after parenteral vaccination at 3 to 9 d of age with a commercial combination modified-live virus vaccine containing BRSV, or a control-vaccine. The total daily clinical score for each calf was computed from the addition of each parameter evaluated using the clinical scoring guidelines. From these values a median was calculated for each study day for both the control group and the vaccinated group. Error bars represent minimum and maximum total clinical scores recorded for each day.
