Figure 2. The kinetics of the memory B cell response to polysaccharide-containing vaccines in primed and unprimed individuals. Data taken from studies reporting on at least one additional time point other than baseline and 1 mo post-vaccination.^5-8 Values are plotted as a percentage of the maximum response within the observed time period and then smoothed (see Figure legend 1; for the “unprimed” group data points were directly connected as smoothing in a similar way was not possible) across all 5 studies represented by the lines for vaccine primed and unprimed individuals, respectively.
