In Step 4, you will receive the vaccine with KLH. It will be given under the skin immediately after you get the infusion of donor cells, and again 4 and 8 weeks after the lymphocyte infusion. After each vaccine, you will receive an injection of a medication called sargramostim (GM-CSF) that helps the body's response to the vaccine. GM-CSF is given under the skin near the site of the vaccination every day for 4 days, starting the day of the vaccination.
