Notably, while baseline antibody levels among children in this trial were about 10-fold to 50-fold lower than pre-immunization levels in adults at this same site, children achieved post-immunization AMA1 antibody levels that were at least as high as those seen in vaccinated adults [17], [20].

While it is not possible to compare antibody levels measured in this trial with those seen in trials of other AMA1 vaccines, based on the relative fold - rise and duration of antibody responses this profile compares favorably with much lower and shorter - lived increases in antibody levels observed in Malian children immunized with AMA1 - C1, an AMA1 vaccine adjuvanted with aluminum hydroxide [19], which provided no measurable protection in a recently reported Phase 2 trial at another site in Mali.
