Study to Compare Self-administered and Nurse-administered Intradermal Influenza Vaccine

June 14, 2011 updated by: Dalhousie University

A Randomized Controlled Trial To Compare The Immunogenicity Of Self-Administered And Nurse-Administered Intradermal Influenza Vaccine

The purpose of this study is to compare the immunogenicity and reactogenicity of self-administered intradermal influenza vaccine (Intanza)to nurse-administered.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

Participants will be randomized at visit one to either receive self-administered or nurse-administered intradermal influenza vaccine (Intanza). A blood sample will be taken prior to vaccination and 21 days post-vaccination. Participants will record information in a memory aid for 7 days including daily temperatures, solicited, unsolicited and general reactions. They will be called on study Day 8 to collect this information. Participants will return 21-24 days later for follow-up serology and review of adverse events.

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

18 years to 60 years (Adult)

Accepts Healthy Volunteers

Yes

Inclusion Criteria:

  • Medically stable persons between age of 18-60
  • Available during the trial period and for follow-up
  • Able to read, understand, and sign informed consent

Exclusion Criteria:

  • Use of experimental vaccines within the month prior to study entry, or expected use of experimental or licensed vaccines or blood/blood products during the duration of the study.
  • Receipt of immunoglobulin or other blood product within 3 months prior to enrollment

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
Immunogenicity
Time Frame: 21 days post-vaccination
That the immunogenicity of self-administered intradermal 2010/11 seasonal influenza vaccine (Intanza) is non-inferior to that of nurse administered intradermal 2010/11 seasonal influenza vaccine. Specifically, that ratio of increase in geometric mean titres between day 0 and day 21 post-vaccination are greater than 2/3 (i.e. GMT (IDS)/GMT (IDN) > 0.65).
21 days 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
Reactogenicity
Time Frame: 7 days post-vaccination
The reactogenicity of self-administered intradermal 2010/11 seasonal influenza vaccine (Intanza) is not significantly greater than that of nurse administered intradermal 2010/11 seasonal influenza vaccine.
7 days post-vaccination
Observational
Time Frame: at vaccination
85% or more of healthy adults can self-administer Intanza successfully; that is, they are willing to self-administer vaccine and successfully administer it, as judged by observation by a trained nurse.
