Table 1 Overview of the design of the three experiments
Experiment number | No of groups (number of pigs per group) | Purpose | Experiment duration following exposure to MU1 (days) | Virulent challenge strains |
|---|---|---|---|---|
1 | 2 (10) | Assess comparative virulence of MU1 | 49 | NSW54 |
2 | 3 (12) | Assess virulence of MU1 AND Assess protection conferred by MU1 | 73 | WA1, BW1, Vic2, NSW5, Q10 (“cocktail”) |
3 | 2 (12) | Assess protection conferred by MU1 and duration | 132 (for vaccinates), 117 for positive controls | WA1, BW1, Vic2, NSW5, Q10 (“cocktail”) |
