Vaccination parameters. A) RRSV-specific antibody titres in serum on days 21 (1 week post-vaccination, left panel) and 28 (2 weeks post-vaccination, right panel), determined by ELISA and expressed as ratio of sample/positive control (S/P). Each symbol represents one animal; median with interquartile range are displayed as horizontal lines; threshold (S/P = 0.4) is indicated with a dashed line. B Percentage of animals tested positive for PRRSV-2 genomes by RT-PCR. C Average numbers of PRRSV genome copies in lung by qRT-PCR, normalised to expression of reference gene RPL32 (mean ± SD). Statistically significant differences (Kruskal–Wallis test, p < 0.05) are indicated using an asterisk
