Challenge with P. yoelii-infected erythrocytes following immunization. Mice were immunized with the IMX108 fusion protein (red lines) (six mice) or with MSP1₁₉ alone (blue lines) (six mice) or were not immunized (black lines) (two mice). Following a challenge infection with 5,000 infected erythrocytes, the parasitemia percentage was determined daily.
