The protective efficacy against challenge by the bites of mosquitoes infected with PfCSP-Tc/Pb parasites

Vaccine	Dose	No. of uninfected mice/total no. (%)
PBS	4	0/10 (0)
WT-AcNPV	4	0/10 (0)
BDES-PfCSP1-gp64	4	1/10 (10)
BDES-sPfCSP2-Spier	4	3/10 (30)a
BDES-sPfCSP2-Spider	4	6/10 (60)b

Mice were screened for PfCSP-Tc/Pb blood-stage infections by microscopic examination of Giemsa-stained thin smears of tail blood after challenge infections. Protection is defined as the complete absence of blood-stage parasitemia on day 14 post-challenge

^{a, b}Each group of immunized mice were compared with the nonimmunized group (PBS) to test for statistically significant differences using Fisher’s exact probability test. ^a p < 0.05; ^b p < 0.01
