<qa>  What is the name of the T cells that will be thawed and injectedThe marrow donors T cells will be thawed and injected through an intravenous line for a period of 10 minutes. The subject may be premedicated with diphenhydramine Benadryl and acetaminophen Tylenol. We would give one dose of the cells on or after day 45 following transplant if the subject agreed and was well enough. If the EBV DNA levels remain high or the subject has persistent disease, she may be eligible to receive up to 5 additional injections of T cells at the original dose at monthly intervals. After the subject has received the T cells, she will be contacted by the research nurse or another member of the study team weekly for 6 weeks, then once every three months for a year so that we can check on hisher progress.
