Results from an Influenza A H1N1 challenge experiment in ferrets.

Values for five symptom indicators and an overall sickness index are presented for each of 21 animals, distributed in 5 experimental groups, coded as 1,2,3,4,and C. Groups 1 to 4 were administered with different doses of HA63–286-RBD, in one or two immunizations (as indicated in column Dose I and Dose II). Group C was the negative control (non-vaccinated). Symbols were assigned based on magnitude deviation with respect to the average value for that particular indicator: no symbol for values lower than average; (†) for values around mean value; and (‡ and value in bold) for values significantly above the average.
