The VNAb titres of groups indicated with (a) or (b) differ statistically at α=0·05. The titres are noted for day 0 (naive sera), day 7 (7 days after primary vaccination) and day 21 (7 days after booster vaccinations) and are expressed as log base 10 of the geometric mean titres (with the range of the values provided in parentheses). The number of surviving animals per group is also indicated in parentheses.
