CHAPEL HILL, N.C., Oct. 26 (UPI) -- The influenza vaccine may not be as effective for those who are obese as it is for others, University of North Carolina at Chapel Hill researchers suggest.
The findings, published online in the International Journal of Obesity, provide evidence explaining a phenomenon first noticed during the 2009 H1N1 flu outbreak -- obesity is associated with an impaired immune response to the influenza vaccination in humans.
