Postvaccination data. (a) Quantification of vaccine strain genome load by qRT–PCR in the serum of vaccinated pigs (mean + SD; 16 pigs per group). In the graph, * indicates that the V + ID group is significantly different from the V+ IM group at D13 PV with p < 0.05. (b) Detection of PRRSV IgG antibodies by ELISA in the serum of vaccinated pigs (mean + SD; 16 pigs per group). Count of interferon gamma-secreting cells (IFNg-SCs) responding to in vitro vaccine strain stimulation among PBMCs purified from blood (c) or among cells isolated from the BAL (d) of vaccinated and unvaccinated pigs (8 vaccinated pigs per group and 4 unvaccinated pigs at D13 PV, 12 pigs per group at D26 PV). On boxplots, different letters above the bars indicate that the groups are significantly different from each other with p < 0.05
