Figure 1From: Anti-idiotypic antibodies reduce efficacy of the attenuated vaccine against highly pathogenic PRRSV challengeRectal temperature (°C) changes in piglets after HP-PRRSV infection. Group 1 to 4 piglets were given Mab2-5G2, aAb2s, 7H12 and normal swine IgG on 0 DPI, respectively, vaccinated on 14 and 28 DPI and challenged with HP-PRRSV on 0 DPC. Group 5 piglets were challenged with HP-PRRSV only and Group 6 piglets received PBS. Each point represents the mean (±S.D) generated from all piglets in each group on each DPC.Back to article page
