About this study
Official title: T and B Cell Immune Responses to Influenza A/H5N1 Vaccine
The purpose of this substudy study is to evaluate the types of cells involved in fighting infection to the A/H5N1 (avian flu virus) vaccine. A maximum of 30 healthy adults ages 18-64 years, enrolled at Stanford University Hospital and participating in another clinical trial (DMID Protocol 04-062) will be enrolled into this substudy to collect additional samples of blood for testing before and approximately one week after each vaccination.
Read the detailed description
A human vaccination trial involving influenza A/H5N1 vaccine with different adjuvants is being conducted in a healthy adult population aged 18-64 years (DMID 04-062) to test the safety, reactogenicity, and immunogenicity of monovalent inactivated influenza A/H5N1 vaccine when given with either alone (no adjuvant), or given along with either alum or MF59. Two doses of the vaccine/adjuvent will be administered day 0 and day 28. This study is linked to DMID protocol 04-062. This protocol is a substudy to collect additional blood samples to specifically evaluate the cell-mediated immune responses generated from the vaccine. Primary goals of this study are 1) to establish reproducible, functional cell-mediate immune response assays to evaluate the magnitude and functional capacity of B cells, NK cells and T cells responding to monovalent subvirion H5 influenza vaccine 2) to evaluate the percent of subjects demonstrating B cell, NK cell, CD8+ and/or CD4+ response. The secondary goal of this study is to examine and compare the adjuvant effect of Alum or MF59 compared to no adjuvant on cell mediated immune responses.
