Overview of double-blind study of local and systemic tolerance and immunogenicity following subcutaneous (SC) and intramuscular (IM) injection of inactivated anti-leptospiral vaccine in healthy volunteers in four randomised parallel groups (SC vaccine, IM vaccine, SC placebo, and IM placebo). D, day; W, week; M, month.

Kinetics of anti-Leptospira interrogans serogroup Icterohaemorrhagiae antibody responses (IgG, IgM and agglutinating antibodies) following successive injections of anti-leptospire vaccine. Volunteers were injected subcutaneously or intramuscularly with inactivated and purified leptospires (2 × 108 L. interogans serogroup Icterohaemorrhagiae) or placebo: day 0, day 14, month 6 and month 30 (vertical arrows). Specific IgM (upper panel) and IgG (middle panel), measured by ELISA, are expressed as mean OD450 nm values relative to cut-off values of and 0.071, respectively. Agglutinating antibodies were measured using the microscopic agglutination test (MAT; lower panel) and their cut-off level was taken to be 1:20, with a reciprocal titre ≥20 being considered positive. (*p <0.05, SC vs. IM routes). SC, subcutaneous; IM, intramuscular; OD, optical density.
