This study shows that HbAS children develop a larger memory CD8+ T cell compartment than HbAA children, and associates this compartment with better control of subsequent onset of infection and parasite density. Our data suggest that central memory CD8+ T cells may play an important role in the relative protection against malaria experienced by HbAS individuals, and further work to investigate this is warranted.
