Flow cytometric analysis of central and effector memory of CD8+T cells in malaria-naïve donors (n = 12) andP. vivax-infected donors (n = 17). A. Central memory (CD8+CD45RO+CCR7+/CD62L+). B. Effector memory (CD8+CD45RO+CCR7−/CD62L−). Mann–Whitney test was used for comparison and the results were expressed as the median with interquartile range. P values are indicated in the graphs.
