Its administration was carried out by intramuscular route because this is the one proposed for use in humans. 0.3 mL of the vaccine or its components was administered to a total of 20 animals per group (10 per each sex). These animals were daily observed and, water and food intake was measured on alternate days determining their body weight with week intervals. The anatomopathological analysis of animals was included at the end of the study. No animal died during the assay or clinical symptoms were observed either. No statistically significant differences (p>0,1) were detected regarding water-food intake and body weight. In the anatomopathological study, macrophagic granulomatous lesions were observed in the rats treated with the vaccine or placebo; this finding is characteristic of vaccines adjuvated with aluminum hydroxide.
