Curiously, the IgG, IgG3 and IgA response to spike protein showed significant correlation to D614G-RBD specific CD19+, CD19+CD20+ and IgD- B cell responses only in the convalescent males who do not develop PCC at 3 months post infection expected (Supplementary Figure S5B, blue asterisks). The gene discussed is CD79A; the disease is infection.
