Brief Summary: This study will compare the safety and immunogenicity of three different dose levels of an experimental recombinant influenza HA protein vaccine to a standard inactivated influenza vaccine in heallthy elderly subjects ages 65-80 Blood and nasal secretions for assessment of antibody responses will be obtained from all subjects prior to and one month after vaccination
Detailed Description: Approximately 400 healthy ambulatory adults ages 65-80 will be randomized into one of four study groups to receive a single immunization of a licensed trivalent inactivated influenza vaccine or one of three dose levels of an investigatioanl trivalent recombinant influenza HA protein vaccine The study will be conducted in 2 stages In the first stage 80 subjects will be randomized 20 per group and receive one vaccination on Day 0 Safety will be evaluated after Stage 1 subjects have completed a 7 day follow-up Enrollment of Stage 2 subjects will begin after the safety data for Stage 1 has been reviewed In Stage 2 320 subjects will be randomized 80 per group and receive one vaccination on Day 0 Blood and nasal secretions will be collected prior to an approximately one month after vaccination to assess antibody responses
