Associations between IgG antibody ELISA responses against two alleles of MSP1₁₉ and AMA1.

<p>Associations are reported between anti-MSP1₁₉ or anti-AMA1 total IgG ELISA titer readouts between two allelic variants of each antigen – ETSR (3D7) and QKNG (K1/Wellcome) for MSP1₁₉, and 3D7 and FVO for AMA1. Responses were assessed following vaccination only, vaccination + CHMI, CHMI only (control volunteers) and in naturally-exposed Kenyan adults (as described in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0107903#pone-0107903-g001" target="_blank">Figure 1B, D</a>). In all cases, Spearman’s rank correlation coefficient and <i>P</i> value are shown. n.d. = not done (too few positive responders). *Relevant data were pooled for analysis from vaccinees receiving either a single vaccine or co-administered vaccines (as described in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0107903#pone-0107903-t001" target="_blank">Table 1</a>).</p><p>Associations between IgG antibody ELISA responses against two alleles of MSP1₁₉ and AMA1.
