Non-survivors produced more CD4+ T-cell IL-10 in response to both Epstein-Barr Nuclear Antigen-1 (EBNA-1) (p = 0·026) and the malaria antigen Plasmodium falciparum Schizont Egress Antigen-1 (p = 0·0158) compared to survivors, and were concurrently deficient in (EBNA-1)-specific CD8+ T-cell derived IFN-γ production (p = 0·002). This evidence concerns the gene CD8A and malaria.
