Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 64 years
  • All sexes
  • Healthy volunteers accepted
  • Adult

Study population: healthy adults male and female ages 18-64 years, participating in another clinical trial (DMID Protocol 04-062)

Who may be able to join

  • All subjects who are eligible and enrolled in 04-062 and have agreed to the extra blood draws for this substudy will be considered for enrollment if they will be receiving 15 micorgrams of the H5N1 vaccine without an adjuvant or with 15 micrograms of the H5N1 vaccine with alum or MF59 adjuvant. Subjects will not be recruited outside the main vaccine trial.
  • Subjects who understand and sign the consent form for this study.
  • Subjects who meet pre-screening qualifications will be eligible for the initial pre-vaccination blood draw.

Who cannot join

  • 1. All subjects who are ineligible for the main monovalent subvirion H5 vaccine trials will not be eligible for the CMI sub-study.

About this study

Official title: T and B Cell Immune Responses to Influenza A/H5N1 Vaccine

The purpose of this substudy study is to evaluate the types of cells involved in fighting infection to the A/H5N1 (avian flu virus) vaccine. A maximum of 30 healthy adults ages 18-64 years, enrolled at Stanford University Hospital and participating in another clinical trial (DMID Protocol 04-062) will be enrolled into this substudy to collect additional samples of blood for testing before and approximately one week after each vaccination.

Read the detailed description

A human vaccination trial involving influenza A/H5N1 vaccine with different adjuvants is being conducted in a healthy adult population aged 18-64 years (DMID 04-062) to test the safety, reactogenicity, and immunogenicity of monovalent inactivated influenza A/H5N1 vaccine when given with either alone (no adjuvant), or given along with either alum or MF59. Two doses of the vaccine/adjuvent will be administered day 0 and day 28. This study is linked to DMID protocol 04-062. This protocol is a substudy to collect additional blood samples to specifically evaluate the cell-mediated immune responses generated from the vaccine. Primary goals of this study are 1) to establish reproducible, functional cell-mediate immune response assays to evaluate the magnitude and functional capacity of B cells, NK cells and T cells responding to monovalent subvirion H5 influenza vaccine 2) to evaluate the percent of subjects demonstrating B cell, NK cell, CD8+ and/or CD4+ response. The secondary goal of this study is to examine and compare the adjuvant effect of Alum or MF59 compared to no adjuvant on cell mediated immune responses.

Questions about this trial

What is this clinical trial studying?

An observational study of Influenza, run by National Institute of Allergy and Infectious Diseases (NIAID) 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 3 inclusion and 1 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 16 Aug 2013. 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.

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 16 Aug 2013; AzTrials last refreshed its copy on 7 Nov 2026.
