Immunogenicity and Safety Study of a Booster Vaccination With a Recombinant H5N1 Influenza HA Vaccine in Primed Adults

February 7, 2011 updated by: UMN Pharma Inc.

A Multicenter, Open-Label Study to Assess the Immunogenicity and Safety of a Booster Vaccination With a Recombinant H5N1 Influenza HA Vaccine in Healthy Young Adults Primed With a Two-Vaccination of a Recombinant H5N1 Influenza HA Vaccine

The study is designed to assess the immunogenicity and safety of one booster vaccination with 45 μg of a recombinant H5N1 influenza (A/Indonesia/05/2005) HA vaccine in healthy young adults, previously primed with a two-vaccination of 3 different doses of a recombinant H5N1 influenza (A/Vietnam/1203/2004) HA vaccine in a priming study (JPIP501-01a, NCT00980447).
