About this study

Background:

  • The Center for Human Immunology, Autoimmunity, and Inflammatory Diseases is conducting research investigating how the swine flu (H1N1) vaccine affects the immune system. The exposure to the new swine flu vaccine gives us a rare opportunity to learn about how the human immune system responds to a new vaccine.
  • Researchers are interested in collecting blood samples from individuals who have received the vaccine. Participants will be selected from a group of healthy volunteers who will be receiving the H1N1 vaccine because it is mandatory for their work at the National Institutes of Health. This protocol will be one of the first studies to characterize the human innate immune response to H1N1 vaccine.

Objectives:

  • To collect blood samples for research purposes before and after participants receive a standard non-research vaccination against swine flu (H1N1).

Eligibility:

  • Healthy individuals 18 years of age and older who are employees of the National Institutes of Health.
  • Individuals who have had confirmed cases of influenza in the past year are not eligible to participate.

Design:

  • Participants will be admitted for a 36-hour inpatient stay, during which blood samples will be taken frequently. Participants will have a standard intravenous catheter (similar to the one used for intravenous infusions) put in place to avoid multiple needle sticks.
  • Participants will be assigned into one of two groups; the two groups differ in the timing of blood draws but not in the overall amount of blood drawn.
  • Group 1: Blood samples 30 minutes before and immediately before vaccination. Additional samples will be taken 2, 4, 6, 8, 10, 12, 14, 16, 18, 24, 30, and 36 hours after vaccination.
  • Group 2: Blood samples 30 minutes before and immediately before vaccination. Additional samples will be taken over the following 36 hours, with exact timing to be determined based on the findings from group 1.
  • All participants will provide blood samples 7 days after being released from the inpatient stay.
  • Because of the amount of blood being drawn for research, participants should not donate blood or take part in any other protocols that collect blood while participating in this study.
Read the detailed description

Seasonal influenza is a major health problem whose impact is typically reduced by vaccination. The H1N1 (swine flu) influenza virus is an emerging pathogen which has the potential to cause devastating morbidity and mortality in the coming months. In June 2009, the World Health Organization declared the H1N1 outbreak to be a global pandemic. At present there are limited data on the early non-specific (innate) immune responses in adult recipients of the H1N1 vaccine.

Therefore the Center for Human Immunology, Autoimmunity, and Inflammatory Diseases proposes this protocol designed to investigate the early innate immune response. Healthy adult subjects (NIH employees) will be admitted as inpatients to receive the FDA-licensed H1N1 vaccine followed by serial blood draws. These samples will be used to perform comprehensive and detailed analyses of the innate immune system s response to vaccination. To our knowledge, this protocol will be the first study to characterize the human innate immune response to H1N1 vaccine. This information may be useful in designing newer, more effective vaccines to prevent the spread of H1N1.

The primary objective is to collect blood to be used strictly for laboratory studies designed to characterize the innate immune response to H1N1 vaccine. Samples will be collected from healthy adult volunteers (NIH employees) at baseline and serially during the first 36 hours after vaccination with the H1N1 vaccine.

Questions about this trial

What is this clinical trial studying?

An observational study of Healthy Volunteers, run by National Heart, Lung, and Blood Institute (NHLBI) 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 4 inclusion and 6 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 6 Oct 2017. 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?

Results of research laboratory assessments.. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00995527, which also lists 3 linked publications.

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 6 Oct 2017.
