The allogeneic breast tumor cell vaccine consists of two types of breast tumor cells developed from the tumor cells of patients with breast cancer. The human granulocyte-macrophage colony-stimulating factor (GM-CSF) gene was used to genetically modify the breast tumor cells to secrete GM-CSF. GM-CSF is a substance made by the body that helps the immune system recognize a tumor and destroy it. The vaccine cells were irradiated to prevent them from growing or dividing. The cells themselves are not radioactive. The cells are stored frozen until the day of vaccination. The total number of cells in each vaccine will be 500,000,000, divided into twelve injections given in the thighs and arms. The choice of twelve injections for each vaccine is based on the volume of the vaccine and a finding that the body has a better chance to respond to the vaccine if it is injected into a number of different areas.
