From: Memory T cell proliferative responses and IFN-γ productivity sustain long-lasting efficacy of a Cap-based PCV2 vaccine upon PCV2 natural infection and associated disease

Figure 7

PCV2-specific ELISPOT positivity upon PCV2 natural exposure. Percentages of responsive animals evaluated upon definition of a cut-off value of 40 IFN-γ SC/106 PBMC in PCV2-vaccinated (PCV2-vac) and unvaccinated (C) pigs in the post-exposure (PE) period to PCV2 natural infection (15-26 weeks of age). PCV2-vac pigs were vaccinated at 3 weeks of age using a PCV2a Cap protein-based subunit vaccine. PBMC were ex vivo re-stimulated for 20 h with 0.25 MOI of a whole PCV2b strain. (*): statistically significant difference between groups (p < 0.05).
