Abstract
The ability of potato-derived major surface antigen of hepatitis B virus (P-HBsAg) to elicit antibody responses to different dosages of P-HBsAg ranging from 0.02 to 30 μg administered orally in mice was examined. All immunized groups produced specific serum IgG and fecal IgA antibodies against P-HBsAg, even at low levels (<5 μg), after administration of a 0.5-μg yeast-derived HBsAg (Y-HBsAg; LG Life Sciences, Republic of Korea) booster.
