Table 1.

Survival and morbidity of BALB/c mice immunized with the DNA vaccines pE1D2 and pcTPANS1 after lethal challenge with DENV2.

Experimental group	Survival	Morbidity	Degree of morbidity
pE1D2	19 (95%)	3 (15%)	0 ± 0.9
pcTPANS1	17 (85%)	4 (20%)	0 ± 1.5
pcTPA	6 (30%)	18 (90%)	3 ± 1.5
DENV2 (non-immunized)	4 (20%)	18 (90%)	4 ± 1.3

Survival and morbidity, followed 21 days after virus challenge, were represented as the absolute number of individual events in the experimental group (n = 20) and the percentage it represents (in parentheses). The degree of morbidity was represented as the median ± standard deviation of the mean.
