Monkey Response

• Host Strain: S. sciureus
• Vaccination Protocol: Monkeys were immunized on days 0, 21, and 42 with 120/~g of protein in PBS/0.1% SDS. Each dose consisted of 1.5ml
  emulsified with Freund's complete adjuvant for the first immunization and Freund's incomplete adjuvant for the others, injected subcutaneously on multiple sites in the back. Control monkeys received the same treatment but without parasite proteins (Bonnefoy et al., 1994).
• Challenge Protocol: All monkeys were challenged on day 56 by intravenous injection of 5 x 10^7 FUP/SP-infected monkey erythrocytes (Bonnefoy et al., 1994).
• Efficacy: The three control monkeys showed a rapid rise of parasitaemia with a prepatent period of 2 days and required drug treatment within 7 days to prevent fatal outcome. Three immunized monkeys developed a reduced parasitaemia with a prepatent period of 2 to 6 days with a maximum peak of parasitaemia of 5-11.6% that dropped spontaneously. The two other immunized monkeys developed parasitaemia similar to the controls and were drug-cured at day 7 (Bonnefoy et al., 1994).
