Safety and Immunogenicity of GPO Seasonal Trivalent Inactivated Influenza Vaccine in Healthy Thai Adults
A Phase I/II Randomized Double Blind Controlled Study to Evaluate the Safety and Immunogenicity of GPO Seasonal Trivalent Inactivated Split Virion Influenza Vaccine in Healthy Thai Adults Aged Between 18 Years to 49 Years
연구 개요
상세 설명
This is a double blind randomized study consisting of two phases - Phase I and Phase II. The same vaccine, a seasonal trivalent inactivated split virion influenza vaccine [A/California/7/2009, reassortant virus NYMC X-181 (H1N1), A/Victoria/210/2009, reassortant virus NYMC X-187 (H3N2), and B/Brisbane/60/2008, reassortant virus NYMC BX-35 virus strains] will be given in both Phase I and Phase II of the study.
The vaccine will be administered via the intramuscular route; the preferred injection site will be the deltoid of the non-dominant arm. After vaccination volunteers will remain at the clinic for at least 30 minutes to observe for any reactogenicity after immunization. Total follow-up is 90 days.
Blood specimens will be collected on Day 0 prior to vaccination, Day 21, Day 60, and day 90.

Number (Percentage) of Participants With Achieving Seroconversions or Significant Increase in Antihemagglutinin Antibody Titer.
기간: 90 days
|
Seroconversion is defined as a 4-fold rise in HAI titer in post-immunization serum relative to pre-immunization serum, or if pre-immunization serum had an undetectable titer (<1:10), attainment of a post-immunization titer of ≥1:40.

Geometric Mean of Immune Response at Every Time of Assessment
기간: 90 days

The analysis was performed only as intention-to-treat (ITT).
The antibody titer values were transformed into log10 titers for calculation of the GMT at every time of assessment (Days 0,21, 60 and 90)
