A University of Minnesota infectious disease expert is questioning the effectiveness of the current flu vaccine.
Doctor Michael Osterholm is concerned because the current flu shot is only 62 percent effective. He is proposing a vaccine that would work for five to ten years.
"I think one of the things that surprises people when they learn about the current flu vaccine, is that the material we use to immunize is a 1940's antigen. Imagine today in 2013 car putting a 1940's transmission on it," said Dr. Osterholm.
The price tag of developing the a new vaccine is the biggest hurdle. Osterholm says it could run upward of $1 billion.
