          -  Subject receiving radiotherapy alone as treatment for his/her haematologic malignancy.

             during the study period. However, the investigational use of a registered product to
             treat the subject's underlying disease, is allowed.

             dose of study vaccine/placebo.

          -  Planned administration during the study of a HZ or varicella vaccine (including an
