NCT02894840

Brief Summary

The study is aim to evaluate the safety and immunogenicity of one dose (15 μg HA per strain per dose) of the GPO seasonal trivalent inactivated split virion influenza vaccine (Tri Fluvac) in healthy adults aged 18 to 49 years over 90 days post-injection.

Outcome Measures

Primary Outcomes (1)

  • Number of Participants With Adverse Events

    All Adverse Events during 90 days will be analysed in terms of percentage and relationship to study vaccine

    90 days

Secondary Outcomes (3)

  • Number (Percentage) of Participants With Achieving Seroconversions or Significant Increase in Antihemagglutinin Antibody Titer.

    90 days

  • Geometric Mean of Immune Response at Every Time of Assessment

    90 days

  • Geometric Mean of Immune Response Increase > 2.5 From Baseline of H1N1,H3N2 and B/Brisbane/60/2008 Antibody Titer

    90 days

Study Arms (2)

an inactivated influenza vaccine

ACTIVE COMPARATOR

20 volunteers in phase I study and 200 volunteers in phase II study will receive a single dose of 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 administered via the intramuscular route; the preferred injection site will be the deltoid of the non-dominant arm.

Biological: an inactivated influenza vaccine
