Which of the following vaccines should not be administered to this patient at this point of time?

Measles, mumps, and rubella vaccine is a live virus vaccine so avoided in transplantation patients with history of GVHD It can be safely given after 24 months if the patient does not have GVHD Patients should be revaccinated against: After 1 year of allogeneic stem cell transplantation After 2 years of allogeneic stem cell transplantation Diphtheria-tetanus 23-Valent pneumococcal polysaccharide Poliomyelitis injection Haemophilus Measles, mumps, and rubella Varicella-zoster
