Figure 5. Temperature over time in Septavacc and control ponies.

Mean rectal temperature was monitored from three days pre-challenge (day 85). Average values and SEM are shown. The insert shows number of days each pony was considered pyrexic, i.e. with a temperature exceeding 39.0°C. P-value in insert: **p = 0.01. Non-vaccinated (open symbols) (n = 7) and Septavacc vaccinated (closed symbols) (n = 7).
