yMSP119-specific antibody titers as measured by ELISA for mice immunized with yMSP119 (closed symbols) and PBS (open symbols) in FA and subsequently challenged with P. yoelii YM. Mice were immunized on day 0 with 20 μg of yMSP119 in CFA and then given booster doses of 20 μg of yMSP119 in IFA on days 21, 42, and 56. A final booster dose of 20 μg of yMSP119 in PBS was given on day 63. Mice were challenged i.v. on day 70 with 104 P. yoelii parasitized red blood cells (indicated by arrows). Day 70 on these graphs is equivalent to day 0 in Fig. 1. Symbols depict antibody titer in individual mice.
