Fig.Ā 2From: Acquired immune responses to three malaria vaccine candidates and their relationship to invasion inhibition in two populations naturally exposed to malariaPrevalence of antibodies in plasma samples from the Ghanaian and Malagasy study population recognizing antigens a AMA1, b MSP1-19, c MSP3 and d 3D7 lysate stratified by country and gender. The antibody titers of the plasma samples were determined by ELISA. Positive reactivity was defined as reactivity higher than the respective negative control plus two times the value of the standard deviation of the negative control. Differences in the antibody prevalence were estimated by the Fisherās exact test and in case of statistical significance corresponding p values are givenBack to article page
