About this study

Official title: Protective Mechanisms Against a Pandemic Respiratory Virus: B- Cell, T-cell, and General Immune Response to Seasonal Influenza Vaccine. Year 2, 2010

This study will investigate response to influenza vaccines in monozygotic and dizygotic twins of different ages.

Read the detailed description

The investigators plan to study the response to influenza vaccines much more broadly and deeply across different age groups and with different vaccine formulations and to probe the influence of genetics on these responses using monozygotic and dizygotic twins. On an investigational basis, investigators plan to compare various immunological responses, identify age-specific biomarkers or clusters of markers, quantify the frequency of influenza-specific T-cells pre- and post-vaccination, and determine the effective breadth of T-cell repertoire to an influenza vaccine within an individual as a function of age and to what degree this is genetically determined.

Twin Groups A-E will receive a single administration of the 2010-2011 formulation of seasonal trivalent inactivated influenza vaccine (TIV). Group F, elderly monozygotic twin participants, will be randomly assigned to receive a single dose of inactivated vaccine, either the usual dose or the High-Dose TIV. Blood samples to conduct the assays described will be taken at pre-immunization, Days 7-10 and 28 post-immunization. Each twin is counted as a single participant. All reporting numbers reflect the number of participants, not the number of twin pairs.

What is being measured

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

  1. Number of Individual Twins Who Received Influenza Vaccine

    All numbers reported are the number of participants, not the number of twin pairs. Each member of a twin was counted individually as a participant.

    Measured: Day 0 to 28

Secondary outcomes (1)
  1. Number of Individual Twins With Related Adverse Events

    Measured: Day 0 to 28 post-immunization

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing High Dose Fluzone® (intramuscular) and Fluzone® (intramuscular) in people with Influenza, run by Stanford University.

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 5 inclusion and 23 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 21 Aug 2017. Status can change between updates, so confirm with the study contact before making plans.

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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 21 Aug 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Individual Twins Who Received Influenza Vaccine (time frame: Day 0 to 28). 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 NCT03022396, which also lists 8 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 21 Aug 2017.
