Distribution of variant-specific antibody responders for MSP-1
at baseline. All responders (black columns), adults (grey columns) and children (white columns) frequencies are displayed for either MSP-119 variants (panel A) or MSP-142 variants (panel B). Note that MSP-142 QTSR was not tested, thus the maximum number of antigens participants could respond to is three. No statistical difference between frequency of adult and children was detected for any group.
