Rapid Evaluation of Pandemic H1N1 Influenza Vaccine in Aboriginal Children and Adults

April 8, 2015 updated by: David Scheifele

PCIRN Evaluation of Pandemic H1N12009 Influenza Vaccine in Aboriginal Children and Adults

The purpose of this study is to assess the safety and effectiveness (immune response) to a licensed H1N12009 influenza vaccine in aboriginal children and adults. The study will enroll 200 healthy adults (ages 20-59 years) and 75 healthy children (ages 6-35 months). Adults will receive one dose of a licensed H1N1 vaccine and children will receive two doses of a licensed H1N1 vaccine approximately 3 weeks apart. Study procedures include: medical history, blood samples and completing a memory aid. Participants will be involved in study related procedures for approximately 3 weeks (adults) or 6 weeks (children).

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

Detailed Description

During the first wave of the H1N12009 pandemic in Canada, persons of aboriginal background were more often hospitalized with severe infections than were other Canadians. Among First Nations members the hospitalization rate was 5 times higher than the national average. Common risk factors were young age (children and younger adults) and underlying health conditions. A high proportion of aboriginal adults have health conditions that predispose to adverse influenza outcomes, including diabetes, asthma, obesity and smoking-related lung diseases.

Aboriginals could benefit substantially from timely, effective vaccination against pandemic influenza and are expected to be among the first Canadians to be offered vaccine when available. The vaccine dosing recommendation will be based on limited studies in the general population, leaving open the question of whether aboriginals will respond satisfactorily to the recommended dosing. Unique social and biological factors among aboriginals could affect their responses to vaccination, reducing protection or increasing adverse effects. Thus it would be optimal to evaluate the safety and immunogenicity of the pandemic vaccine among the earliest aboriginal recipients, to inform the subsequent vaccination of other aboriginal groups.

The objectives of this study are two-fold:

  1. To evaluate the safety and immunogenicity of H1N12009 influenza vaccine in a convenience sample of children and adults of aboriginal background (First Nations, Metis and Inuit) with emphasis on subgroups at greatest risk of severe disease.
  2. To complete this evaluation soon after the pandemic vaccines become available so as to inform the subsequent use of the vaccines in the aboriginal population.

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.

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
Time Frame
Occurrence of adverse events (AEs) for days 0-6 after each vaccination
Time Frame: Day 7 and Day 21 post vaccination
Day 7 and Day 21 post vaccination
Occurrence of serious adverse events (SAEs) and other significant health events up to 21 days after each vaccination
Time Frame: Day 7 and Day 21 post vaccination
Day 7 and Day 21 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
Time Frame
Comparison of baseline and post-immunization antibody titres
Time Frame: Day 21 (adults) and Day 42 (children)
Day 21 (adults) and Day 42 (children)
