<qa>  How many teaspoonfuls of blood will be taken after the injections?We will continue to follow the subject in the BMT clinic after the injections. To learn more about the way the T cells are working, an extra 40 mls about 8 teaspoonfuls of blood will be taken pre-infusion, 4 hours after the infusion, 3-4 days post infusion optional and at 1, 2, 4 and 6 weeks after the T cell infusions, and then at 3, 6, 9, and 12 months post infusion. The blood should come from the central intravenous line, and should not require extra needle sticks.
