Anti-HBsAg serum IgG and subclass titers detected by ELISA in BALB/c mice immunized with HBsAg, encapsulated/adsorbed in mesoporous SBA-15 or adsorbed in Al(OH)3 by subcutaneous (SC) or oral (OR) routes. The titers were detected 7, 14 and 30 days after the booster. A group of animals immunized with rHBsAg was used as a reference for the unpaired Student t test analysis, *p < 0.05; ⋯ p < 0.001. Antibody titers at days 7, 14 and 30 after the booster were also used as a reference for the unpaired Student t test analysis, °p < 0.05 [reproduced from the work by Scaramuzzi et al., 2011)]. |
