Intersecting Venn diagram showing the abundance of DEGs. The number of genes differentially expressed at three different time points (6, 24 and 72 hpv) of PRRSV vaccination compared to the control (before vaccination). The numbers in overlapping area(s) represent the differential expression of genes shared among the time points
