  • Written informed consent (and assent, if applicable) obtained;
  • Potential research participant received or will receive H1N1 swine-origin monovalent influenza vaccine within 24 hours of study entry.

Who cannot join

  • Proven history, by RT-PCR, of H1N1 swine-origin influenza infection prior to study entry;

About this study

This study will evaluate the immunogenicity and safety of inactivated H1N1 swine-origin monovalent influenza vaccine in immunocompromised children and young adults.

Read the detailed description

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.

Study groupRoleWhat they receive
H1N1 pandemic influenza vaccine recipientChildren 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. This study will document Seroprotection (a post-vaccine antibody response ≥ an HI titer of 1:40).

    Measured: 1.5 years

Secondary outcomes (1)
  1. This study will document seroconversion rates (a 4-fold or greater rise in HI titer comparing pre- and post-vaccine sera).

    Measured: 1.5 years

Questions about this trial

What is this clinical trial studying?

An observational study of H1N1 Pandemic Flu, run by St. Jude Children's Research Hospital at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 7 Oct 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

This study will document Seroprotection (a post-vaccine antibody response ≥ an HI titer of 1:40). (time frame: 1.5 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Oct 2011.
