	Low dose	High dose
Sporozoites (liver-stage parasites)	Mosquito bite or 100 sporozoites iv: no pre-erythrocytic immunity (Figure 3A/B)	10,000 sporozoites iv: pre-erythrocytic immunity (Figure 3B)
Blood-stage parasites	Blood-stage infection curtailed by chloroquine: partial blood-stage immunity (Figure 4)	Fulminant, self-cured blood-stage infection: blood-stage immunity (Spence et al., 2013); pre-erythrocytic immunity (Figure 6)
