The flu shot, it might be said, is the black sheep of the vaccine family. In good years, people ignore it because they think the flu is no big deal. In bad years -- like this one -- they complain that it doesn't work well enough. But the biggest problem, says Dr. Gregory Poland, a leading vaccine researcher, is that scientists are still scrambling to understand the elusive virus and come up with a better alternative…"Like every single man-made product, influenza vaccine is imperfect,'' said Poland, head of the Vaccine Research Group at the Mayo Clinic. "But I liken it to seat belts. Who would want to be in a crash without a seat belt?"
