Study Overview
Brief Summary
This research is being done to understand the effects of certain types of bone marrow transplant (BMT) on the immune system. Your doctors are planning a BMT, using one of your family members as the bone marrow donor, for your cancer. Part of that BMT involves a chemotherapy drug, called Cyclophosphamide (Cytoxan), given after the transplant. This research is being done to understand the effects of Cyclophosphamide on the immune system.
Detailed Description
The research will involve giving your donor a vaccine against a certain infection, before the bone marrow donation: either a vaccine against hepatitis (the hepatitis A vaccine), or a vaccine against pneumonia (Prevnar). You will then get both of these vaccines following your transplant. By studying how much these vaccines may improve your immune system, we hope to better understand the effects of the BMT with Cyclophosphamide on the immune cells.
Prevnar is a pneumococcal vaccine (pneumococcus is a bacteria that can cause pneumonia and other infections). It is approved by the Food and Drug Administration (FDA) for the prevention of infections in children. It is not usually given to adults. Hepatitis A vaccine is approved by the FDA for the prevention of hepatitis A (a liver infection) in children and adults.
The vaccines are not approved for bone marrow donors or for vaccinating adults after BMT (using these vaccines in this research is investigational). The FDA is allowing the use of these vaccines in this research study.
Certain people getting BMT followed by Cyclophosphamide may join, if their donors might also join. Your bone marrow donor must take part in this study, in order for you to continue on this study

- •Donors inclusion:
- •Donor age > 18 years.
Exclusion Criteria

Outcomes
Primary Outcomes
T-cell Immunity Augmentation
Time Frame: up to 6 months
Number of participants in which patient-donor pairs were not pre-immune to hepatitis A or CRM197, show augmented T-cell immunity when the vaccine is also given to the bone marrow donor.
Secondary Outcomes
- Recipient Vaccine-specific T-cell Response Post-transplant, Before Vaccination(up to 6 months)
- Recipient Vaccine-specific T-cell Response After Post-transplantation Vaccine(up to 6 months)
