Brief Summary
RATIONALE: Studying immune response to flu vaccine in patients who have undergone a stem cell transplant may help doctors plan the best treatment. PURPOSE: This clinical trial is studying flu vaccine to see how well it works in preventing infection in patients who have undergone a stem cell transplant and in healthy volunteers.

Outcome Measures
Primary Outcomes (1)
Humoral and cellular memory immune responses in patients and healthy volunteers
At Day 0 and 30, 90 and 180 days after vaccine in healthy participants and also at 360 days in transplant patients . 4-5 times in the first 2 years after transplant for transplant patients not vaccinated. One time in normal participants not vaccinated.
Secondary Outcomes (4)
Incidence rate of influenza or respiratory incidence in patients after vaccination
1 year after vaccination or two years after transplant if not vaccinated.
Impact of graft-vs-host disease on immune reconstitution and vaccine response
1 year after vaccination or two years after transplant if not vaccinated.
Impact of age ≥ 60 years on immune reconstitution of after vaccination
1 year after vaccination or two years after transplant if not vaccinated.
Differences between antibody and cytokine (CD8 and CD4) response
180 days after vaccine in healthy participants. 360 days after vaccine in transplant patients. 2 years after transplant for transplant patients not vaccinated. One time in normal participants not vaccinated.
Study Arms (2)
Flu vaccine
Patients and normal volunteers who have received a flu vaccine
Non-vaccine
Patients and normal volunteers who have not received the flu vaccine
Interventions
Patients or normal volunteers who will be vaccinated against the flu.
This test will determine the level of antibodies in participants who have been vaccinated against the flu and those who have not been vaccinated against the flu.
This test will count the number of T cells (the cells that kill the flu virus) in participants who have been vaccinated against the flu and those who have not been vaccinated against the flu.
Eligibility Criteria
