Report: Mistakes in medical studies have skyrocketed since 2001

According to an investigation published by the Wall Street Journal, fifteen times more scientific papers were retracted from medical journals last year than in 2001.

Today on American Morning, Elizabeth Cohen, senior medical correspondent, breaks down how these types of mistakes get made and explains what the retractions mean for the average American.
