Overlap and allele specificity of AMA1-specific invasion-inhibitory antibodies. a Overlap in AMA1-specific invasion-inhibitory activity for the three AMA1 alleles with the highest prevalence of inhibitory antibodies. Numbers of PNG individuals whose serum showed specific inhibition of each line are shown. b Proportion of PNG samples (n = 98 or 99) showing specific inhibition of genetically engineered P. falciparum expressing one allele of AMA1 that also inhibited growth of lines expressing other AMA1 alleles.
