Active immunotherapy of pulmonary metastases established for 3 days. BALB/c mice were inoculated with 5×105 CT26.CL25 tumor cells. Three, or 3 and 10 days after tumor inoculation, mice were inoculated with 5×105 p.f.u. i.v. of the designated virus and checked daily for survival. Results shown are from a single experiment, although data is shown in three panels for clarity. Shown are mice receiving two immunizations, 3 and 10 days after tumor inoculation in (A) and (B). Mice receiving a single immunization 3 days after tumor inoculation are shown in C). An independent repeat experiment showed similar results
