Characterization of the intra‐tumoral infiltrates at day 11 post‐vaccination, that is, during the tumor regression phase, showed: (i) a large increase in the percentage of CD45+ hematopoietic cells (Fig 3A), and (ii) a significant increase in the percentages of CD8+ T cells within the CD45+ population, and (iii) a significant decrease in the percentages of CD4+ T cells within the CD45+ population (Fig 3B). The gene discussed is CD8A; the disease is neoplasm.
