Cellular and Humoral Immune Response to Primary and Secondary Immunization With Subvirion H5N1 Vaccines

Completed · Phase 1

Conditions studied: Influenza

In brief

The purpose of the study is to evaluate safety and compare how the body reacts to 2 different strengths of the Clade (specific type of H5N1 virus) 2 H5N1 flu vaccine when given as a single vaccination with a high dose (90 mcg) or low dose (15 mcg) to volunteers who have received at least 2 doses of the Clade 1 H5N1 vaccine, in a previous National Institute of Health study or who have never received a H5N1 vaccine (naïve). Previously vaccinated subjects (in studies 04-0063, 05-0090, 05-0127) will receive either 15 or 90 mcg of H5N1 vaccine. Multiply boosted volunteers who participated study 05-0043 and received Clade 1 and 3 vaccines, will receive the same dose (15mcg). Vaccine naïve subjects will receive 2 doses of vaccine (15 or 90 mcg) separated by 28 days. Blood samples will be collected. 115 volunteers age 18-64 may participate in study related procedures for approximately 7 months.
