From: A CpG oligodeoxynucleotide enhances the immune response to rabies vaccination in mice
RVNA response induced by reduced injections of HDCV-CpG. Balb/c mice (n = 10) were immunized i.m. with HDCV for 5 injections and HDCV plus CpG for 5, 4, 3 and 2 injections. Serum samples were collected on D35. RFFIT was used to detect RVNA in the sera of mice. The antibody titer was expressed in international units per milliliter (IU/ml), calculated in comparison with the national reference standard serum
