The administration of booster immunisations should be started no earlier than 6 months after completion of chemotherapy treatment for leukaemia, lymphoma or solid tumour.
Children treated with High Dose Chemotherapy, followed by Autologous or Allogeneic Haematopoietic Stem Cell Transplant (HSCT) will receive a comprehensive revaccination programme at 12 months post transplant, which reflects their more profound immune suppression.
Important Note: the current unit policy is not to measure functional antibody status in children after completion of standard dose chemotherapy.
