Frequency of type 1 (A) and type 2 (B) PRRSV-specific IFN-γ-SC/106PBMC. Sows that received PRRSV vaccine followed by type 1 PRRSV challenge (group 1, □); sows that received PRRSV vaccine followed by type 2 PRRSV challenge (group 2, ■); non-vaccinated sows challenged with type 1 PRRSV (group 3, ○); non-vaccinated sows challenged with type 2 PRRSV (group 4, ●); and sows that received PRRSV vaccine (group 5, △).*Significant (P < 0.05) difference between group 1 and group 3. †Significant (P < 0.05) difference between group 2 and group 4.
