Protection from macroscopic (a) and microscopic (b) metastases in wild-type normal BALB/c females following surgical tumor resection (day 15) and immunization with (CpG + EMT6) in mice receiving ongoing infusion (at 72 h intervals) with anti-CD200 mAb. Controls received no additional treatment, or isotype control, Ig. Mice were sacrificed at 50 days post initial tumor inoculation. Data represent mean ± SD for group (numbers to side of each bar show survivors for group). *^,**p < 0.05 (p < 0.01) compared with control; nd non-detectable
