IgG titer to HCR/A and BA15. (A) The HCR/A or BA15 was administered to mice (0.1μg/head) in an initial intramuscular injection (0 days) and in two subsequent boosts (14 and 28 days). The results showed that IgG titer of BA15 was markedly higher than that of HCR/A. (B)The HCR/A or BA15 was administered to mice (10 μg/head) in an initial intramuscular injection (0 days) and in two subsequent boosts (14 and 28 days).IgG titer was analyzed until 15 weeks. IgG titer of BA15 was higher than that of HCR/A during 15 weeks.
