CCL2 and infection: In particular, proteins that are associated with the T cell (CXCL9 and CXCL10) and antibody responses (INF-γ, MCP1, L10, PDL1, CXCL10, ADA, and CXCL11) after infection were also associated with the T cell and antibody responses after vaccination, highlighting important similarities between infection- and vaccine-induced immunity.
