Study Summary
The purpose of this research study is to compare how the body reacts to different strengths of a new H5N1 flu vaccine. Researchers will also look at how antibodies are made after subjects receive the H5N1 flu vaccine. Participants will include at least 240 healthy males and females, aged 65 and older. The vaccine is given as an injection or shot in the arm. Subjects will receive 3 doses of vaccine at Day 0, Month 1 and Month 6.
