A new study found that the effects of the flu shot are diminished in overweight people.

According to the International Journal of Obesity, U.S. scientists tested blood samples from immunized people of various weights over a one year period.

They found overweight people were unable to maintain the same anti-body response as thinner people during the year after getting a flu shot.
