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 8 to 100 years
  • All sexes
  • Healthy volunteers accepted
  • Child, Adult, Older adult

Who may be able to join

  • Healthy, ambulatory 8-17 year old identical twins, 8-30 year old non-twins, or 70-100 year old elderly non-twin adults.
  • Willing to complete the informed consent process.
  • Availability for follow-up for the planned duration of the study at least 28 days after immunization.
  • Acceptable medical history by medical history and vital signs.

Who cannot join

  • Prior vaccination with seasonal TIV or LAIV or H1N1.
  • Prior off-study vaccination with the current seasonal TIV or LAIV
  • Allergy to egg or egg products, or to vaccine components
  • Life-threatening reactions to previous influenza vaccinations
  • Asthma or history of wheezing
  • Active systemic or serious concurrent illness, including febrile illness on the day of vaccination
Show all 26Show fewer
  • History of immunodeficiency (including HIV infection)
  • Known or suspected impairment of immunologic function, including, but not limited to, clinically significant liver disease, diabetes mellitus treated with insulin, moderate to severe renal disease, or any other chronic disorder which, in the opinion of the investigator, might jeopardize volunteer safety or compliance with the protocol.
  • Blood pressure >150 systolic or >95 diastolic at first study visit
  • Hospitalization in the past year for congestive heart failure or emphysema.
  • Chronic Hepatitis B or C.
  • Recent or current use of immunosuppressive medication, including systemic glucocorticoids (corticosteroid nasal sprays and topical steroids are permissible in all groups; inhaled steroid use is not permissible except for non-LAIV Group C only). Use of oral steroids (<20mg prednisone-equivalent/day) may be acceptable for volunteers 70-100 yrs of age after review by the investigator.
  • Participants in close contact with anyone who has a severely weakened immune system should not receive LAIV (Groups A and B only)
  • Malignancy, other than squamous cell or basal cell skin cancer (includes solid tumors such as breast cancer or prostate cancer with recurrence in the past year, and any hematologic cancer such as leukemia).
  • Autoimmune disease (including rheumatoid arthritis treated with immunosuppressive medication such as Plaquenil, methotrexate, prednisone, Enbrel) which, in the opinion of the investigator, might jeopardize volunteer safety or compliance with the protocol.
  • History of blood dyscrasias, renal disease, or hemoglobinopathies requiring regular medical follow up or hospitalization during the preceding year
  • Use of any anti-coagulation medication such as Coumadin or Lovenox, or anti-platelet agents such as aspirin (except up to 325 mg. per day), Plavix, or Aggrenox must be reviewed by investigator to determine if this would affect the volunteer's safety.
  • Receipt of blood or blood products within the past 6 months
  • Medical or psychiatric condition or occupational responsibilities that preclude participant compliance with the protocol
  • Inactivated vaccine 14 days prior to vaccination

  • Donation of the equivalent of a unit of blood within 6 weeks prior to enrollment
  • Any condition which, in the opinion of the investigator, might interfere with volunteer safety, study objectives or the ability of the participant to understand or comply with the study protocol.

About this study

Official title: Protective Mechanisms Against a Pandemic Respiratory Virus. Project 1: B-cell Immunity to Influenza. Technical Development Project 1: Measuring the Immunome: Genomic Approaches to B-cell Repertoire - Years 2 (2010) & 3 (2011)

In this exploratory study, investigators will be looking at immune response differences between age groups and between the two different influenza vaccines given to identical twins, vaccine-naive young adults and elderly participants.

Read the detailed description

This is an exploratory study of healthy children and adults who are given either standard trivalent, inactivated influenza vaccine (TIV) or live, attenuated influenza vaccine (LAIV). There are no exclusions for gender, ethnicity or race. Following confirmation of written informed consent, baseline blood samples will be drawn from all study participants prior to immunization. The volunteers enrolled in any the three groups (A,B,C) cannot have been immunized with previous year's seasonal influenza vaccine. The identical twins in Groups A will be randomized to each receive a different vaccine (TIV or LAIV) than their twin. The non-twin children in Group B will also be randomly assigned to receive either TIV or LAIV. Non-twin elderly adults in Group C will be given standard TIV. All participants will receive a single dose of their assigned influenza vaccine, either by intramuscular (IM) injection (TIV) or intranasal application (LAIV).

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Fluzone and FluMist 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 4 inclusion and 26 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 Jun 2018. 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 9 Mar 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 Participants 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 NCT03020498, which also lists 4 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 Jun 2018.
