Description détaillée
This is a prospective observational study. This study will not dictate vaccine administration, nor the vaccine product to be used. It will collect data in St Jude patients who will receive the vaccine as part of their clinical care per institutional guidelines. Research participants will receive two doses of inactivated H1N1 swine-origin monovalent influenza vaccine administered 28 days apart as part of clinical care. Each dose contains 15 mcg of hemagglutinin antigen (HA).Follow-up visits will be scheduled 28 days after each dose and at day 208+/- 14 days for blood work. The day of administration of the first vaccine dose is counted as day 0. At each of these visits, blood will be collected to assess for immunogenicity. Research participants will be given a diary card to record symptoms for 28 days . They will be asked to bring this diary back at the next visit. Other vaccine-related adverse events will also be collected by retrospective chart review.
Children and young adults between the ages of 6 months and 21 years and 13 kg or greater in body weight who have an underlying diagnosis of cancer, HIV, sickle cell disease or receipt of a stem cell transplant more than a year prior to study entry and who will receive inactivated H1N1 swine-origin monovalent influenza vaccine in the winter/fall of 2009-2010 as part of their routine clinical care.

H1N1 pandemic influenza vaccine recipient
Children and young adults between the ages of 6 months and 21 years and 13 kg or greater in body weight with underlying conditions of cancer, HIV, sickle cell disease or receipt of a stem cell transplant more than a year prior to study entry and who will receive inactivated H1N1 swine-origin monovalent influenza vaccine in the winter/fall of 2009-2010 as part of their routine clinical care.Target total accrual of up to 400 children and young adults stratified based on their underlying diagnosis as follows: 150 children or young adults with cancer, 100 with human immunodeficiency virus (HIV), 100 with sickle cell disease, and 50 with receipt of a stem cell transplant more than a year prior to study entry.
