Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Subjects who previously participated in study FID29 will be invited to participate in this revaccination study. They will be assigned to 1 of 3 groups based on the group they were previously randomized to and the vaccine received in study FID29.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

65 years and older (Older Adult)

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Participants Reporting Solicited Injection Site and Systemic Reactions After Fluzone Intradermal or Fluzone Intramuscular or Fluzone High-dose Vaccine Injection
Time Frame: Days 0 through 7 post vaccination
Solicited injection site reactions: Pain, Erythema (redness), Swelling, Induration, Ecchymosis, Pruritus. Solicited systemic reactions: Fever, (Temperature), Headache, Malaise, Myalgia, and Shivering.
Days 0 through 7 post vaccination

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Geometric Mean Titers (GMTs) Before and After Vaccination With Fluzone Intradermal or Fluzone Intramuscular or Fluzone High-dose Vaccine Injection
Time Frame: Day 0 and Day 28 post-vaccination
Serum antibody titers for the influenza vaccine serogroups A/H1N1, A/H3N2, and B were assessed by the hemagglutinin inhibition (HAI) assay.
Day 0 and Day 28 post-vaccination
Percentage of Participants Who Achieved Seroprotection Post-Vaccination With Fluzone Intradermal or Fluzone Intramuscular or Fluzone High-dose Vaccine
Time Frame: Days 0 and 28 post-vaccination
Seroprotection was defined as hemagglutinin inhibition (HAI) titer ≥ 1:40 at Day 28.
Days 0 and 28 post-vaccination
Percentage of Participants Who Achieved Seroconversion Post-Vaccination With Fluzone Intradermal or Fluzone Intramuscular or Fluzone High-dose Vaccine
Time Frame: Day 28 post vaccination
Seroconversion was defined as either a pre-vaccination hemagglutinin inhibition (HAI) titer < 1:10 and a post-vaccination titer ≥ 1:40 or a pre- vaccination titer ≥ 1:10 and a minimum 4 fold increase at 28 days post vaccination.
Day 28 post vaccination

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
