Phase 1 Evaluation of the Safety and Immunogenicity of a Replication-Competent Adenovirus Serotype 4-vectored H5N1 Influenza Candidate Vaccine - Ad4-H5-Vtn
The purpose of this study is to compare the safety and immunogenicity over a 9-month period of five different dosages of Ad4-H5-Vtn in volunteers (Vaccinees) who receive three doses of the study vaccine or placebo. In addition, transmission of Ad4-H5-Vtn will be evaluated in all Household Contacts residing with the vaccinated volunteers. Vaccinees also may participate in a substudy in which they receive a booster vaccination with the licensed Influenza Virus Vaccine, H5N1 (Sanofi Pasteur).
