IL10 and malaria: The total IL10 response and frequency of IFNγ/IL10 coproducing cells, but not IL10 single-producing cells, were weakly associated with malaria incidence in the preceding year (rho = 0.14, p = 0.02, rho = 0.16, p = 0.01 and rho = 0.026, p = 0.67, respectively), consistent with prior reports (8).
