Revaccination With Subunit Influenza A/Vietnam/1203/2004 (H5N1) Vaccine
A Phase 1 study testing Influenza A/Vietnam/1203/2004 (H5N1; sanofi pasteur) in people with Influenza, run by National Institute of Allergy and Infectious Diseases (NIAID) at 1 site in United States.
Trial summary
The purpose of this study is to determine whether having received an H5 vaccine in the past primes the immune system to respond rapidly to another dose of H5 vaccine. One hundred seventeen participants in a previous vaccine study (involving the A/Hong/Kong/97 virus) during the fall of 1998 at the University of… Read more about this study

About this study
Official title: Revaccination of Healthy Subjects With Intramuscular Inactivated Subunit Influenza A/Vietnam/1203/2004 (H5N1) Vaccine Representing a Drifted Variant
The purpose of this study is to determine whether having received an H5 vaccine in the past primes the immune system to respond rapidly to another dose of H5 vaccine. One hundred seventeen participants in a previous vaccine study (involving the A/Hong/Kong/97 virus) during the fall of 1998 at the University of Rochester will be eligible to enroll in this study. Participation in this study will up to 64 days and will involve donation of small samples of blood 7, 28, and 56 days after vaccination.
Read the detailed description
This is an open label, phase I evaluation of a single dose of an investigational inactivated, subunit influenza A/Vietnam/1203/2004 (H5N1) vaccine in subjects who were previously vaccinated with a vaccine made from an antigenically distinct variant of H5N1. The study is designed to determine whether immunization with an antigenic variant can prime for responses to a single dose of vaccine representing the current pandemic threat. The primary objective is to determine the ability of a priming dose of rec H5 HA 1997 vaccine administered 7 years previously to result in booster responses to an inactivated subunit influenza A/Vietnam/1203/2004 (H5N1) vaccine. The secondary objectives are to 1) determine the safety of a booster dose of intramuscular inactivated subunit influenza A/Vietnam/1203/2004 (H5N1) vaccine in healthy adults, previously vaccinated with rec H5 HA 1997 vaccine and 2) evaluate the relationship between priming, levels of antigen-specific memory B and T cells , and the response to reactivation. The study will be performed at a single site, and will enroll as many previously vaccinated subjects as are available and eligible, up to a maximum of 117. Subjects will receive a single intramuscular dose of 90 mcg of the inactivated subunit influenza A/Vietnam/1203/2004 (H5N1) vaccine. Blood for assessment of antibody responses will be obtained before and at time points after vaccination. Subjects participating in the optional sub study will also have blood obtained for enumeration of memory B and T cells. Subjects will be followed for solicited adverse events for 7 days by memory aids and for 56 days for unsolicited adverse events. This study is linked to DMID protocol 08-0059.

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 14 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 12 Aug 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.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00240903, which also lists 1 linked publication.
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 12 Aug 2011.
