The purpose of this study is to compare the immunogenicity and reactogenicity of self-administered intradermal influenza vaccine (Intanza)to nurse-administered.
Full Title of Study: “A Randomized Controlled Trial To Compare The Immunogenicity Of Self-Administered And Nurse-Administered Intradermal Influenza Vaccine”
- Study Type: Interventional
- Study Design
- Allocation: Randomized
- Intervention Model: Parallel Assignment
- Primary Purpose: Prevention
- Masking: Single (Outcomes Assessor)
- Study Primary Completion Date: January 2011
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.
- Biological: Intanza
- 0.1 mL of Intanza intradermally at visit # 1
- Biological: Intanza
- 0.1 mL of Intanza intradermally at visit #1
Arms, Groups and Cohorts
- Active Comparator: Intanza – self-administered
- Self-administered intradermal influenza vaccine
- Active Comparator: Intanza – nurse-administered
- Nurse-administered intradermal influenza vaccine
Clinical Trial Outcome Measures
- 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).
- 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.
- 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.
Participating in This Clinical Trial
